To exit.
Japanese Patent No. 3096613

  However, in the configuration of Patent Document 1, since the display elements for the first image and the display elements for the second image are connected to a common scanning line and are alternately arranged in the horizontal direction, the period during which each scanning line is selected In the (horizontal scanning period), it is necessary to supply a signal corresponding to each pixel of the first image and a signal corresponding to each pixel of the second image to each of the plurality of pixels in the selected row in parallel. Therefore, there is a problem that processing and a circuit for synthesizing the first image and the second image are complicated. In view of the above circumstances, an object of the present invention is to simplify the configuration and processing for displaying a plurality of images in different directions.

  In order to solve the above problems, a display device according to the present invention includes a plurality of scanning lines extending in a first direction, a plurality of signal lines extending in a second direction intersecting the first direction, and a plurality of signal lines. A plurality of element rows in which a plurality of display elements corresponding to each of the signal lines are arranged in the first direction, and a plurality of first display elements among the plurality of display elements. A first state in which the display light of each of the plurality of second display elements travels in the same direction, display light of each of the plurality of first display elements, and display light of each of the plurality of second display elements And a plurality of scanning lines that belong to each of two or more element rows and correspond to separate signal lines. When the above first display elements belong to each of a plurality of first scanning lines connected to each of the two or more element rows Two or more second display elements corresponding to the monitor separate signal lines and a plurality of second scan lines connected to each. The display device of the present invention is used in various electronic devices.

  In the above configuration, only the first display element of the plurality of display elements is connected to the first scanning line, and only the second display element of the plurality of display elements is connected to the second scanning line. Even when separate images are displayed on the first display element and the second display element, a signal supplied to each signal line when the first scanning line is selected is generated according to the common image, A signal supplied to each signal line when two scanning lines are selected can be generated according to a common image. Therefore, a complicated process or circuit for synthesizing the image displayed by the first display element and the image displayed by the second display element is not required. Further, it is possible to select an operation for displaying one image in the same direction and an operation for displaying a plurality of images in another direction according to the state of the light control body.

  Note that the display light of the first display element is a concept that includes both light emitted from the first display element to the observation side and light irradiated from the illumination device to the first display element. Therefore, the light control body may be arranged on either the observation side (front side) with respect to the element part and the back side (for example, a gap between the element part and the illumination device) with respect to the element part. The same applies to the display light of the second display element.

  In a specific aspect of the present invention, the first display elements and the second display elements are alternately arranged along each of the first direction and the second direction. According to the above aspect, the display light of the first display element and the display light of the second display element can be reliably and evenly separated in different directions.

When the light control body is in the second state, the polarity of the applied voltage in each of the plurality of display elements is the same scan. Each display element corresponding to each signal line connected to the line is opposite in polarity and is inverted in units of the first display element and the second display element adjacent in the second direction. A data voltage specifying the applied voltage of the display element is output to each signal line for each selection period. ; And a signal line driver circuit. In the above aspect, since the display element in which the applied voltage is set to positive polarity and the display element in which the applied voltage is set to negative polarity are arranged in a dispersed manner, an image is displayed. Accordingly, even if the gradation of the display element is different, the gradation of the image can be made uniform. In addition, since the polarity of the applied voltage is reversed in units of the first display element and the second display element that are adjacent in the second direction, the configuration in which the applied voltage has the opposite polarity for all the display elements that are adjacent in the second direction. Compared with, the power consumed in the drive circuit is reduced. Furthermore, since the period of inversion of the polarity of the data voltage only changes between when the light control body is in the first state and when it is in the second state, the processing and configuration in the signal line driver circuit is simplified. There is an advantage.

  In the display device according to the second aspect of the present invention, the plurality of display elements are divided into a plurality of element groups in units of a predetermined number corresponding to a plurality of display colors, and each of the plurality of first scanning lines and the plurality of display elements are divided.

The polarity of the voltage is the same for a predetermined number of display elements belonging to the same element group, the opposite polarity is set for each element group connected to the same scanning line in the first direction, and the second direction. In the display elements adjacent to each other, the polarities of the applied voltages in each of the plurality of display elements are set to the predetermined number of display elements belonging to the same element group when the light control body is in the second state. Are connected to the same scanning line in the first direction. A data voltage that specifies an applied voltage of each display element is selected for a selection period so that each element group in contact has a reverse polarity and is inverted in units of the first display element and the second display element adjacent in the second direction. And a signal line driving circuit for outputting to each signal line. In the above aspect, the applied voltage of each display element is set to the same polarity in the same element group, so that the gradation relationship of each display color is accurately set. In addition, since an element group in which the applied voltage of each display element is set to positive polarity and an element group in which the applied voltage of each display element is set to negative polarity are arranged in a dispersed manner, an image is displayed. Even when the gray level of the display element varies depending on the polarity of the voltage, the gray level of the image can be made uniform. Further, since the polarity of the applied voltage is reversed in units of the first display element and the second display element that are adjacent in the second direction, the configuration in which the applied voltage has a reverse polarity for all the display elements that are adjacent in the second direction. Compared with, the power consumed in the drive circuit is reduced. Further, since the period of inversion of the polarity of the data voltage only changes between when the light control body is in the first state and when it is in the second state, the processing and configuration in the signal line driver circuit is simplified. There is an advantage.

<A: First Embodiment>
FIG. 1 is a plan view of a display device according to a first embodiment of the present invention. As shown in FIG. 1, the display device 100 includes a display body 10 and a light control body 80. The display body 10 is a liquid crystal display panel in which liquid crystal is sealed in a gap between two substrates facing each other at a predetermined interval. The light control body 80 is a plate-like member disposed on the observation side (image output side) of the display body 10. In addition, although the illuminating device (backlight) which illuminates the display body 10 is actually arrange | positioned in the back side (the opposite side to the light control body 80 on both sides of the display body 10) of the display body 10, in FIG. The illustration is omitted for convenience.

  FIG. 2 is a block diagram showing an electrical configuration of the display body 10. As shown in FIGS. 1 and 2, the display body 10 includes an element portion Q in which a plurality of display elements E (E1, E2) are arranged in a planar shape. Each of the plurality of display elements E is a liquid crystal element in which a liquid crystal is interposed in the gap between each electrode (pixel electrode and counter electrode) facing each other, and a gradation (transmission of irradiation light from the illumination device) according to an applied voltage. Rate) changes.

  As shown in FIG. 2, in the element portion Q, 2m scanning lines 12 (12A, 12B) extending in the X direction and n signal lines 14 extending in the Y direction intersecting the X direction. Are formed (m and n are natural numbers). The plurality of display elements E are arranged in a matrix in the X direction and the Y direction corresponding to each intersection of the scanning line 12 and the signal line 14. That is, in the element portion Q, a plurality of sets R (hereinafter referred to as “element rows”) in which n display elements E corresponding to the signal lines 14 are arranged in the X direction are juxtaposed in the Y direction. In practice, a transistor having a gate connected to the scanning line 12 is interposed between the display element E and the signal line 14, but the transistor is not shown in FIGS. 1 and 2 for convenience.

  As shown in FIG. 2, the plurality of display elements E are classified into a first display element E1 and a second display element E2. In FIG. 2 and subsequent drawings, only the first display element E1 is hatched for the sake of convenience in order to distinguish the first display element E1 from the second display element E2. The first display elements E1 and the second display elements E2 are alternately arranged along each of the X direction and the Y direction. That is, in the element portion Q, the odd-numbered display elements E in the odd-numbered element rows R (m) and the even-numbered display elements E in the even-numbered element rows R are the first display elements. E1 and the second display element E2 includes the even-numbered display elements E in the odd-numbered element rows R and the odd-numbered display elements E in the even-numbered element rows R in the element portion Q. is there.

  The operation mode of the display device 100 is selectively controlled to either the first mode or the second mode. The first mode is an operation mode in which a single image G0 is displayed using both the first display elements E1 and the second display elements E2. On the other hand, the second mode is an operation mode in which the display of the first image GA by each first display element E1 and the display of the second image GB by each second display element E2 are executed in parallel. The first image GA and the second image GB are stereoscopic images having parallax with each other, for example.

  The light control body 80 in FIG. 1 is an optical body that variably controls the direction of light emitted from each display element E. The light control body 80 of this embodiment is controlled to the first state in the first mode and is controlled to the second state in the second mode. The first state is a state in which light emitted from each first display element E1 and light emitted from each second display element E2 travel in the same direction. On the other hand, in the second state, the emitted light from each first display element E1 travels in a predetermined direction (hereinafter referred to as “first display direction”), and the emitted light from each second display element E2 is first displayed. This is a state of traveling in a direction different from the direction (hereinafter referred to as “second display direction”). For example, when a display body displays a stereoscopic image having parallax with each other (more specifically, a left-eye image is displayed on each first display element E1 and a right-eye image is displayed on a second display element E2. The first display direction corresponds to the direction of the left eye of the observer, and the second display direction corresponds to the direction of the right eye of the observer.

  As shown in FIG. 1, the light control body 80 of this embodiment includes a plate-like element in which first regions 81 and second regions 82 corresponding to the display elements E are alternately arranged along the X direction and the Y direction. It is. Each first region 81 is controlled to either a state of transmitting the irradiation light or a state of blocking the irradiation light. Each second region 82 is a region through which irradiation light is transmitted. As the light control body 80 described above, for example, a liquid crystal barrier in which a liquid crystal element in which liquid crystal is interposed in a gap between opposing electrodes is arranged in the first region 81 is suitable. In the first state (first mode), both the first regions 81 and the second regions 82 are controlled to be translucent. Therefore, the emitted light from each first display element E1 and the emitted light from each second display element E2 travel in the same direction. On the other hand, in the second state (second mode), as shown in FIG. 1, each first region 81 is controlled to be light-shielding, and each second region 82 is maintained to be translucent. Therefore, the emitted light from the first display element E 1 passes through the second regions 82 of the light control body 80 and travels in the first display direction, and the emitted light from the second display element E 2 is transmitted to each of the light control bodies 80. The light passes through the second region 82 and proceeds in the second display direction.

  As shown in FIG. 2, the 2m scanning lines 12 are divided into m first scanning lines 12A and m second scanning lines 12B. The first scanning lines 12A and the second scanning lines 12B are alternately arranged in the Y direction (that is, the second scanning lines 12B are located in the gaps between the adjacent first scanning lines 12A). The first scanning line 12A includes n first display elements E1 belonging to two element rows R adjacent in the Y direction and connected to separate signal lines 14 (that is, having different positions in the X direction). Connected. In other words, in the first scanning line 12A, the odd-numbered first display element E1 in the odd-numbered element row R and the even-numbered first display element E1 in the even-numbered element row R are shared. Connected. Further, n second display elements E2 belonging to two element rows R adjacent in the Y direction and connected to separate signal lines 14 are connected to the second scanning line 12B. That is, the second display element E2 in the even-numbered column in the odd-numbered element row R and the second display element E2 in the odd-numbered column in the even-numbered element row R are commonly connected to the second scanning line 12B. Is done. As described above, only the plurality of first display elements E1 are connected to the first scanning line 12A, and only the plurality of second display elements E2 are connected to the second scanning line 12B.

  FIG. 3 is a timing chart for explaining the operation of the display device 100. As shown in FIG. 3, the scanning line drive circuit 32 scans Y (YA [1] to YA [m], YB [1] to be output to each scanning line 12 in both the first mode and the second mode. ] To YB [m]) are set to active levels in a predetermined order, so that each of the 2m scanning lines 12 is selected for each selection period (horizontal scanning period) H within each unit period (vertical scanning period) F. Select sequentially. The scanning signals YA [1] to YA [m] are output to the first scanning lines 12A, and the scanning signals YB [1] to YB [m] are output to the second scanning lines 12B. The scanning line driving circuit 32 of this embodiment sequentially selects each of the 2m scanning lines 12 in the order of arrangement along the Y direction. Since the first scanning lines 12A and the second scanning lines 12B are alternately arranged along the Y direction, the scanning line driving circuit 32 has the first scanning lines 12A and the second scanning lines 12B as shown in FIG. Are alternately selected every selection period H.

  The control circuit 40 in FIG. 2 controls the scanning line driving circuit 32 and the signal line driving circuit 34. For example, the control circuit 40 outputs a synchronization signal and a control signal to the scanning line driving circuit 32 and the signal line driving circuit 34, and outputs a mode designation signal MOD and gradation data D to the signal line driving circuit 34. The mode designation signal MOD is a signal indicating the operation mode (first mode or second mode) selected by the control circuit 40. In the first mode, the gradation data D designates the gradation of each pixel of the image G0. In the second mode, the gradation data D specifies the gradation of each pixel in each of the first image GA and the second image GB.

  The signal line drive circuit 34 in FIG. 2 outputs data voltages X [1] to X [n] specifying the applied voltage of each display element E to the n signal lines 14 in parallel for each selection period H. . The data voltage X [j] output to the signal line 14 in the j-th column (j = 1 to n) in the selection period H in which the scanning line 12 in the i-th row (i = 1 to 2 m) is selected is The display element E in the j-th column belonging to the i-th row is set to a voltage value corresponding to the gradation specified by the gradation data D. A specific operation of the signal line drive circuit 34 will be described below with reference to FIGS. 4 and 5 together with FIG. FIG. 4 is a conceptual diagram showing the contents of display in the first mode, and FIG. 5 is a conceptual diagram showing the contents of display in the second mode.

  When the mode designation signal MOD supplied from the control circuit 40 indicates the first mode, the signal line drive circuit 34 displays the image in the selection period H in which the scanning lines 12 (12A, 12B) are selected as shown in FIG. Data voltages X [1] to X [n] corresponding to the gradation data D of G0 are generated and output to each signal line 14. Therefore, as shown in FIG. 4, the gradation of all the display elements E (first display element E1 and second display element E2) of the element portion Q is set according to the gradation data D of the image G0. Since the light control body 80 in the first mode is in the first state in which both the first region 81 and the second region 82 are set to be translucent, each observer is positioned in a different direction with respect to the display pair 10. Visually recognizes the common image G0.

  On the other hand, when the mode designation signal MOD indicates the second mode, the signal line driving circuit 34, as shown in FIG. 3, the gradation data of the first image GA during the selection period H in which the first scanning line 12A is selected. Data voltages X [1] to X [n] corresponding to D are generated and output to each signal line 14, and in the selection period H in which the second scanning line 12B is selected, the gradation data D of the second image GB. The data voltages X [1] to X [n] corresponding to are generated and output to each signal line 14.

  Since only the plurality of first display elements E1 are connected to the first scanning line 12A, in the selection period H in which the first scanning line 12A is selected in the second mode, n connected to the first scanning line 12A. The applied voltage of each of the first display elements E1 is set according to the data voltages X [1] to X [n] (according to the gradation data D of the first image GA). Similarly, in the selection period H in which the second scanning line 12B is selected, the applied voltages of the n second display elements E2 connected to the second scanning line 12B are the data voltages X [1] to X [n]. (According to the gradation data D of the second image GB). Accordingly, in the second mode, as shown in FIG. 5, the first image GA is displayed on the first display element E1, and the second image GB is displayed on the second display element E2.

  The light control body 80 in the second mode is in the second state in which the first region 81 is controlled to be light-shielding and the second region 82 is controlled to be light-transmitting. FIG. 6 shows an image (part (A)) output in the first display direction and an image (part (B)) output in the second display direction in the f-th unit period F in the second mode. It is a schematic diagram shown. As shown in the part (A) of FIG. 6, the display light from the first display element E1 is emitted in the first display direction, so that the first image GA is output in the first display direction. ), The display light from the second display element E2 is emitted in the second display direction, so that the second image GB is output in the second display direction.

  As described above, in the present embodiment, only the first display element E1 is connected to the first scanning line 12A and only the second display element E2 is connected to the second scanning line 12B. The data voltages X [1] to X [n] output to the signal lines 14 are generated from the gradation data D of the common image (GA, GB). Therefore, there is an advantage that complicated processing and configuration of synthesizing the gradation data D of the first image GA and the gradation data D of the second image GB for each selection period H are unnecessary.

  In addition to the above operation, the signal line drive circuit 34 has a predetermined reference voltage (for example, the counter electrode) so that the applied voltage of each display element E changes from one of the positive polarity and the negative polarity to the other in a predetermined cycle. The polarity of the data voltages X [1] to X [n] with respect to the voltage) is selected. Hereinafter, the display of an image by the element unit Q and the polarity of the voltage applied to the display element E (the condition of the polarity of the data voltage X) will be described with reference to FIGS. FIG. 3 shows the polarities (+, −) of the data voltage X [j] in the jth column and the data voltage X [j + 1] in the (j + 1) th column. . 4 and 5 illustrate the polarity (+, −) of the voltage applied to each display element E in each of the f-th unit period F and the (f + 1) -th unit period F. Yes.

  In both the first mode and the second mode, the signal line drive circuit 34 inverts the polarity of the data voltage X [j] supplied to one display element E every unit period F as shown in FIG. Let Therefore, as shown in FIGS. 4 and 5, each display element is divided into the f-th unit period F (part (A)) and the (f + 1) -th unit period F (part (B)). The polarity of the applied voltage of E is reversed.

  Further, in any of the first mode and the second mode, the signal line driving circuit 34 outputs data to be output in one selection period H to each signal line 14 adjacent in the X direction, as shown in FIG. The voltage X (X [j], X [j + 1]) is set to a reverse polarity. Therefore, as shown in FIG. 4 and FIG. 5, among the n first display elements E1 connected to the same first scanning line 12A, each odd-numbered first display element E1 and each even-numbered first display element E1. The applied voltage is opposite to that of the display element E1. Similarly, among the n second display elements E2 connected to the same second scanning line 12B, the applied voltages are reversed between the second display elements E2 in the odd rows and the second display elements E2 in the even rows. Polarity.

  When the first mode is instructed, the signal line drive circuit 34 inverts the polarity of the data voltage X every selection period H as shown in FIG. In this embodiment, since the first scanning line 12A and the second scanning line 12B are alternately selected every selection period H, the data voltage X [j] is one of the first scanning line 12A and the second scanning line 12B. Is set to a positive polarity in the selection period H in which is selected, and is set to a negative polarity in the selection period H in which the other of the first scanning line 12A and the second scanning line 12B is selected. Therefore, paying attention to the 2m display elements E connected to the same signal line 14, as shown in FIG. 4, the polarity of the applied voltage is different between the first display element E1 and the second display element E2 adjacent in the Y direction. Invert.

  On the other hand, when the second mode is instructed, the signal line drive circuit 34, as shown in FIG. 3, has two selection periods H (the selection period H of the first scanning line 12A and the second scanning line 12B). The polarity of the data voltage X is inverted in units of the selection period H). For example, the data voltage X [j] is set to positive polarity in two selection periods H in which each of the scanning signal YA [1] and the scanning signal YB [1] is at a high level, and the scanning signal YA [2] and In two selection periods H in which each of the scanning signals YB [2] is at a high level, the data voltage X [j] is inverted to a negative polarity. Accordingly, as shown in FIG. 5, when attention is paid to the 2m display elements E connected to the same signal line 14, two display elements E (the first display element E1 and the second display element E2) adjacent in the Y direction. ), The polarity of the applied voltage is reversed.

  Even when the same gradation is designated by the gradation data D, the actual gradation of the display element E may differ depending on the polarity of the applied voltage. Therefore, in the second mode, if the applied voltages of all the first display elements E1 (or all the second display elements E2) within the unit period F have the same polarity, the same over a plurality of unit periods F. Even when the gradation is specified, there is a problem that the gradation of the first display element E1 fluctuates for every unit period F (and flicker becomes apparent). In the present embodiment, since the first display element E1 having a positive applied voltage and the first display element E1 having a negative applied voltage are mixed within one unit period F, the applied voltage corresponds to the polarity of the applied voltage. There is an advantage that the difference in gradation is averaged in the element portion Q and is hardly perceived by an observer.

  In the first mode, the polarity of the data voltage X (X [j], X [j + 1]) set so as to have a reverse polarity in each signal line 14 adjacent in the X direction is selected every selection period H. Invert to. On the other hand, in the second mode, the polarity of the data voltage X (X [j], X [j + 1]) set to have the opposite polarity in each signal line 14 adjacent in the X direction is selected to be two. The period H is reversed as a unit. That is, in the present embodiment, the period for inverting the polarity of the data voltage X only changes between the first mode (selection period H) and the second mode (two selection periods H), and is arranged in the X direction. The polarity arrangement of the data voltage X supplied to each signal line 14 is common to the first mode and the second mode. Therefore, a configuration in which the data voltage X is generated by the signal line driving circuit 34 as compared with a configuration in which the number of signal lines 14 serving as a unit for inverting the polarity of the data voltage X is different between the first mode and the second mode. There is an advantage that the processing is simplified.

<B: Second Embodiment>
Next, a second embodiment of the present invention will be described. In addition, about the element in which an effect | action and a function are equivalent to 1st Embodiment in each following form, the same code | symbol as the above is attached | subjected and each detailed description is abbreviate | omitted suitably.

  FIG. 7 is a block diagram showing an electrical configuration of the display body 10 according to the second embodiment of the present invention. As shown in FIG. 7, each display element E in the element portion Q corresponds to one of a plurality of display colors (red (R), green (G), blue (B)). That is, the display element E corresponding to red emits color light having a wavelength corresponding to red to the observation side, the green display element E emits green color light, and the blue display element E emits blue color light. Each display element E in the (3k-2) th column corresponds to red, each display element E in the (3k-1) th column corresponds to green, and each display element E in the 3kth column is blue. Corresponding (k is a natural number). Accordingly, 2m display elements E arranged in the Y direction correspond to the same color (stripe arrangement). However, the arrangement of the display colors can be arbitrarily changed.

  Similar to the first and second embodiments, each of the m first scanning lines 12A out of the 2m scanning lines 12 includes n first display elements E1 belonging to two element rows R. The n second display elements E2 belonging to the two element rows R are connected to each of the m second scanning lines 12B. As shown in FIG. 7, the n display elements E connected to the common scanning line 12 include three display elements E connected to the three adjacent signal lines 14 (that is, red, green, and blue). Are divided into element groups P in units of three display elements E) corresponding to. By controlling the gradation of each of the three display elements E in each element group P for each element group P, an image of a plurality of colors is displayed on the element portion Q.

  The signal line driving circuit 34 includes a plurality (n / 3) of distribution circuits 35 arranged for every three adjacent signal lines 14 (that is, for each element group P arranged in the X direction). As shown in FIG. 8, the distribution circuit 35 (demultiplexer) includes an input point N and three switches SW (SWR, SWG, SWB). The input signal N is supplied with the original signal S0. The original signal S0 is a one-system voltage signal that designates the gray scales (applied voltages) of the three display elements E belonging to one element group P by time division. The distribution circuit 35 distributes the original signal S0 into three systems by sequentially turning on each of the three switches SW (SWR, SWG, SWB). The signal line drive circuit 34 generates three systems of data voltages X corresponding to one element group P based on each of the three systems of signals distributed by the distribution circuit 35 and outputs the generated data voltages X to the signal lines 14.

  FIG. 9 is a timing chart showing the operation of the display device 100. 10 and 11 show the content of the image displayed on the element portion Q and the applied voltage of each display element E for each of the f-th unit period F and the (f + 1) -th unit period F. It is a conceptual diagram which shows polarity (+,-) of. 10 corresponds to the state in the first mode, and FIG. 11 corresponds to the state in the second mode. As shown in FIG. 9, in both the first mode and the second mode, the scanning line driving circuit 32 arranges the 2m scanning lines 12 in the order of arrangement (that is, the first scanning line 12A and the second scanning line 12B). The operation of selecting (alternately) is the same as in the first embodiment.

  On the other hand, the signal line driving circuit 34 designates the gradation (applied voltage) of the n display elements E connected to the scanning line 12 in the selection period H in which the i-th scanning line 12 is selected. The n data voltages X [1] to X [n] are generated according to the operation of each distribution circuit 35 and output to each signal line 14. The symbol “_R” shown in FIG. 9 for the data voltage X means a voltage value corresponding to the gradation of the red pixel in the image (G0, GA, GB). Similarly, the symbol “_G” means a voltage value corresponding to the gradation of the green pixel, and the symbol “_B” means a voltage value corresponding to the gradation of the blue pixel.

  The relationship between the operation mode selected by the control circuit 40 and the display contents in the element part Q is the same as in the first embodiment. That is, as shown in FIG. 9, the data voltages X [1] to X [n] in the first mode are generated according to the gradation data D of the image G0. Therefore, all the display elements E in the element part Q display the image G0. On the other hand, as shown in FIG. 9, the data voltages X [1] to X [n] in the second mode are generated according to the gradation data D of the first image GA in the selection period H of the first scanning line 12A. Then, it is generated according to the gradation data D of the second image GB in the selection period H of the second scanning line 12B. Accordingly, the first image GA is displayed on the first display element E1, and the second image GB is displayed on the second display element E2.

  Next, the polarity of each data voltage X (the polarity of the voltage applied to the display element E) will be described in detail. In both the first mode and the second mode, the operation of setting the polarity of the data voltage X so that the polarity of the voltage applied to each display element E is inverted every unit period F is the same as that in the first embodiment. It is the same.

  In both the first mode and the second mode, the signal line drive circuit 34 sets the data voltage X output to each of the three signal lines 14 corresponding to one element group P to the same polarity. For example, as shown in FIG. 9, data voltages X [j] to X [X] to be supplied to the three signal lines 14 corresponding to one element group P from the jth column to the (j + 2) th column. [j + 2] has the same polarity. Therefore, as shown in FIGS. 10 and 11, the applied voltages of the three (red, green, blue) display elements E belonging to the same element group P have the same polarity.

  In both the first mode and the second mode, the signal line drive circuit 34 inverts the polarity of the data voltage X with the three signal lines 14 corresponding to one element group P as a unit. For example, as shown in FIG. 9, data voltages X [j] to X [X] to be supplied to the three signal lines 14 corresponding to one element group P from the jth column to the (j + 2) th column. [j + 2] and three signal lines 14 from the (j + 3) th column to the (j + 5) th column corresponding to the other device group P adjacent to the device group P The data voltages X [j + 3] to X [j + 5] are opposite in polarity. Therefore, as shown in FIGS. 10 and 11, the applied voltage of each display element E is opposite in polarity in two element groups P adjacent to each other in the X direction among the plurality of element groups P connected to the same scanning line 12. It becomes.

  When the first mode is instructed, the signal line drive circuit 34 inverts the polarity of the data voltage X every selection period H as shown in FIG. Therefore, paying attention to the 2m display elements E connected to the same signal line 14, as shown in FIG. 10, the polarity of the applied voltage is different between the first display element E1 and the second display element E2 adjacent in the Y direction. Invert. On the other hand, when the second mode is instructed, as shown in FIG. 9, the signal line drive circuit 34 has two selection periods H (the selection period H of the first scanning line 12A and the second scanning line 12B). The polarity of the data voltage X is inverted in units of the selection period H). Therefore, as shown in FIG. 11, when attention is paid to the 2m display elements E connected to the same signal line 14, two display elements E (first display element E1 and second display element E2) adjacent in the Y direction. ), The polarity of the applied voltage is reversed.

  FIG. 12 is a schematic diagram illustrating an image (part (A)) output in the first display direction and an image (part (B)) output in the second display direction in the f-th unit period F. is there. As shown in part (A) of FIG. 12, the first display element E1 having a positive applied voltage and the first display element E1 having a negative applied voltage are dispersedly mixed so that the first display element E1 has a positive polarity. One image GA is displayed. Similarly, the second image GB is displayed in the second direction by mixing the second display element E2 having a positive applied voltage and the second display element E2 having a negative applied voltage. Therefore, as in the first embodiment, there is an advantage that the difference in gradation of the display element E according to the polarity of the applied voltage is averaged in the element portion Q and is hardly perceived by the observer.

  Since the applied voltages of the three display elements E belonging to one element group P are set to the same polarity, compared to the case where the polarity of the applied voltage of each display element E is different in the element group P, the element group The relationship (balance) of the gradation of each display element E in P is set accurately. Therefore, it is possible to improve the color reproducibility of the image. Further, since the applied voltages of the three display elements E belonging to one element group P have the same polarity, the voltage at the input point N has the same polarity within the period in which each distribution circuit 35 distributes the original signal S0 to the three systems. Maintained. Therefore, the voltage at the input point N is compared with the case where the polarity of the voltage applied to each display element E is different within the element group P (that is, when the polarity of the original signal S0 varies within the period of distributing the original signal S0). Is suppressed (and power consumption in the signal line driver circuit 34 is reduced).

  In the second mode, the applied voltage is set to the same polarity in the first display element E1 and the second display element E2 adjacent in the Y direction. Therefore, the number of times the polarity of the data voltage X is inverted and the voltage value of the data voltage X compared to the case where the polarity of the applied voltage is inverted in all the display elements E adjacent in the Y direction (for example, the first mode). The fluctuation amount of is suppressed. Therefore, there is an advantage that power consumed in the signal line driving circuit 34 is reduced. When one of the first image GA and the second image GB is a black image and the other is a white image, the difference in applied voltage between the first display element E1 and the second display element E2 increases. Therefore, the present embodiment in which the number of inversions of the polarity of the data voltage X and the fluctuation amount of the voltage value are suppressed is particularly effective.

  In the first mode, the applied voltage of each display element E is set to have a reverse polarity in the element group P adjacent in the X direction, and the applied voltage is set to the same polarity in each display element E in the same element group P. The polarity of the data voltage X is inverted every selection period H. On the other hand, in the second mode, the applied voltage of each display element E has the opposite polarity in the element group P adjacent in the X direction, and the applied voltage has the same polarity in each display element E in the same element group P. The polarity of the set data voltage X is inverted in units of two selection periods H. That is, in the present embodiment, as in the first embodiment, the cycle of inverting the polarity of the data voltage X changes between the first mode (selection period H) and the second mode (two selection periods H). However, the polarity arrangement of the data voltage X supplied to each signal line 14 arranged in the X direction is common to the first mode and the second mode. Therefore, a configuration in which the data voltage X is generated by the signal line driving circuit 34 as compared with a configuration in which the number of signal lines 14 serving as a unit for inverting the polarity of the data voltage X is different between the first mode and the second mode. There is an advantage that the processing is simplified.

<C: Third Embodiment>
FIG. 13 is a timing chart showing the operation of the display device 100 according to the third embodiment of the present invention. As shown in FIG. 13, each of the plurality of unit periods F includes a first period T1 extending from the start point of the unit period F to a predetermined time length, and from the lapse of the first period T1 to the end point of the unit period F. It is divided (divided into two equal parts) to the second period T2. As understood from the waveforms of the scanning signals YA [1] to YA [m] and the scanning signals YB [1] to YB [m] illustrated in FIG. 13, the scanning line driving circuit 32 has the first mode and the second mode. In any of the modes, each of the m first scanning lines 12A is sequentially selected in the first period T1 of each unit period F, and m second scans are performed in the second period T2 of each unit period F. Each of the lines 12B is selected sequentially.

  When the first mode is instructed, the signal line driving circuit 34 applies the data voltages X [1] to X [n] corresponding to the gradation data D of the image G0 in each of the first period T1 and the second period T2. It outputs to each signal line 14 every selection period H. On the other hand, when the second mode is instructed, the signal line driving circuit 34 uses the data voltages X [1] to X [n] corresponding to the gradation data D of the first image GA in each selection period H of the first period T1. And the data voltages X [1] to X [n] corresponding to the gradation data D of the second image GB are output in each selection period H of the second period T2.

  In both the first mode and the second mode, the data voltage X (X [j], X [j + 1]) output to each signal line 14 adjacent in the X direction is set to a reverse polarity. In the first mode, the polarity of the data voltage X [j] is maintained at the same polarity in each selection period H in the first period T1, and is the same in each selection period H in the second period T2. And the opposite polarity is set in the first period T1 and the second period T2. In the second mode, the polarity of the data voltage X [j] is inverted every selection period H in the first period T1 and is inverted every selection period H in the second period T2. The point that the polarity of the data voltage X supplied to one display element E is reversed every unit period F is the same as in the first embodiment.

  Since the scanning line driving circuit 32 and the signal line driving circuit 34 operate as described above, paying attention to the entire unit period F, in the first mode, the voltage of the polarity shown in FIG. The image G0 is displayed on the element E1 and the second display element E2, and in the second mode, the first image GA is displayed on the first display element E1 by applying the voltage having the polarity shown in FIG. The second image GB is displayed on the display element E2. Therefore, the same operation and effect as the first embodiment are exhibited.

<D: Fourth Embodiment>
FIG. 14 is a timing chart showing the operation of the display device 100 according to the fourth embodiment of the present invention. Similarly to the third embodiment, the scanning line driving circuit 32 sequentially selects each of the m first scanning lines 12A for each selection period H in the first period T1 in each of the plurality of unit periods F. In the second period T2, each of the m second scanning lines 12B is sequentially selected every selection period H. The configuration in which each display element E of the element portion Q is divided into the element group P according to the display color is the same as in the second embodiment.

  In both the first mode and the second mode, as in the second embodiment, the data voltages X (X [j], X [j] supplied to the three signal lines 14 corresponding to one element group P are used. +1], X [j + 2]) are set to the same polarity, and the polarity of the data voltage X is inverted with the three signal lines 14 corresponding to one element group P as a unit. In the first mode, the polarity of the data voltage X [j] is maintained at the same polarity in each selection period H in the first period T1, and is the same in each selection period H in the second period T2. And the opposite polarity is set in the first period T1 and the second period T2. On the other hand, in the second mode, the polarity of the data voltage X [j] is inverted every selection period H in the first period T1 and is inverted every selection period H in the second period T2. The point that the polarity of the data voltage X supplied to one display element E is reversed every unit period F is the same as in the second embodiment.

  Since the scanning line driving circuit 32 and the signal line driving circuit 34 operate as described above, paying attention to the entire unit period F, in the first mode, the voltage of the polarity shown in FIG. The image G0 is displayed on the element E1 and the second display element E2, and in the second mode, the first image GA is displayed on the first display element E1 by applying the voltage having the polarity shown in FIG. The second image GB is displayed on the display element E2. Therefore, the same operation and effect as the second embodiment are exhibited.

<E: Modification>
Various modifications can be made to the above embodiments. Specific modifications are exemplified below. Two or more aspects may be arbitrarily selected from the following examples and combined.

(1) Modification 1
The contents of the first image GA and the second image GB are not limited to stereoscopic images. The display device 100 according to each of the above embodiments is also preferably used when providing a separate image to each of a plurality of observers who are in different directions with respect to the display device 100. For example, when the display device 100 is used for a car navigation device, various moving images provided to the observer at the passenger seat are displayed on the first display element E1 as the first image GA and provided to the driver. A route guidance image is displayed on the second display element E2 as a second image GB.

(2) Modification 2
In the second embodiment and the fourth embodiment, the unit period F is composed of one first period T1 and one second period T2, but the first period T1 and the second period T2 in the unit period F are The number ratio is arbitrarily changed. For example, according to the configuration in which a plurality of first periods T1 and one second period T2 are set in each unit period F, the first image GA displayed on the first display element E1 in the first period T1 is displayed. It is updated in a shorter cycle than the second image GA. Therefore, for example, by selecting a moving image with a large image change as the first image GA and selecting a still image or a moving image with a small image change as the second image GB, the first image GA is selected so that the subject changes smoothly. Compared with a configuration in which one image GA is displayed and the second image GB is updated at the same cycle as the first image GA, the operation speed required for the scanning line driving circuit 32 and the signal line driving circuit 34 is reduced. There is an advantage that.

  In the configuration in which the first period T1 for selecting each first scanning line 12A and the second period T2 for selecting each second scanning line 12B are individually set as in the second and fourth embodiments. A configuration in which the number of scanning lines 12 selected by the scanning line driving circuit 32 is different between the first period T1 and the second period T2 is also preferable. For example, only the first scanning lines 12A from the first row to the m / 2th row are selected from the m first scanning lines 12A in the first period T1, and m lines are selected in the second period T2. In the configuration for selecting each of the second scanning lines 12B, the first image GA displayed only on the upper half of the element portion Q and the second image GB displayed on the entire element portion Q are output in different directions. Is possible.

(3) Modification 3
The configuration of the light control body 80 is appropriately changed. For example, instead of the liquid crystal element of the liquid crystal barrier, an electrophoretic element that is in a translucent or light-shielded state by migration of charged particles (for example, a microcapsule in which charged particles colored in white or black are sealed together with a fluid) Is also suitable in the first region 81. In addition, a liquid crystal lens in which liquid crystal is sealed inside a translucent casing shaped into a lens shape is employed as the light control body 80. In the liquid crystal lens, by controlling the refractive index of the liquid crystal according to the applied voltage, the first state in which the emitted light from each display element E is emitted to the front of the display device 100, and the output from the first display element E1. It is possible to select one of the second state in which the emitted light and the light emitted from the second display element E2 travel in different directions. A configuration in which the light control body 80 is disposed in the gap between the display body 10 and the illumination device on the back side is also suitable. When the light control body 80 is controlled to the first state, the emitted light from the illumination device passes through each display element E and is emitted to the observation side, and when the light control body 80 is controlled to the second state, the illumination is performed. Of the light emitted from the apparatus, light that passes through the second region 82 and travels in the first display direction passes through the first display element E1, passes through the second region 82, and travels in the second display direction. The light passes through the second display element E2.

(4) Modification 4
In each of the above embodiments, one scanning line driving circuit 32 selects the m first scanning lines 12A and the m second scanning lines 12B, but the scanning line driving circuit that selects each first scanning line 12A. A configuration in which 32 and the scanning line driving circuit 32 for selecting each second scanning line 12B are separately arranged is also preferable.

(5) Modification 5
In each of the above embodiments, the uppermost element row R is composed of only n / 2 first display elements E1, and the lowermost element row R is composed of only n / 2 second display elements E2. As shown in FIG. 15, the first display element E1 and the second display element E2 are alternately arranged in the uppermost and lowermost element rows R as in the other element rows R as shown in FIG. You may let them.

(6) Modification 6
In each of the above embodiments, the signal line driving circuit 34 selectively uses the grayscale data D of all the pixels of both the first image GA and the second image GB to use the data voltages X [1] to X [n] is generated, but gradation data D corresponding to each pixel corresponding to each first display element E1 in the first image GA and each pixel corresponding to the second display element E2 in the second image GB. A configuration in which only the control circuit 40 supplies the signal line drive circuit 34 is also suitable.

(7) Modification 7
A liquid crystal element is only an example of a display element. The display element employed in the configuration in which only the plurality of first display elements E1 are connected to the first scanning line 12A and only the plurality of second display elements E2 are connected to the second scanning line 12B emits light itself. There is no distinction between the self-luminous type and the non-luminous type that changes the transmittance of external light, and the distinction between the current-driven type driven by current supply and the voltage-driven type driven by electric field (voltage) application. is there. For example, an organic EL (Electroluminescence) element, an inorganic EL element, a field electron emission element (FE (Field-Emission) element), a surface conduction electron emission element (SE (Surface conduction Electron emitter) element), a ballistic electron emission element (BS) The present invention is applied to display devices using various display elements such as (Ballistic electron Emitting) elements, LED (Light Emitting Diode) elements, electrophoretic elements, and electrochromic elements. In other words, a display element is an electro-optical element (pixel) whose gradation (optical characteristics such as transmittance and luminance) changes in accordance with an electrical action such as supply of current or application of voltage (electric field). However, the configuration in which the polarity of the applied voltage of the display element is reversed with time as exemplified in the above embodiments is a display element in which continuous application of a direct current component causes problems such as deterioration of characteristics (typical). Is particularly suitable for a liquid crystal element).
