Unevenly, asymmetric；Also, the center of blue subpixels 12 to the center of green sub-pixels 11 distance and red sub-pixel 13
Center to the center of green sub-pixels 11 distance it is inconsistent；Therefore it is easy to produce the problems such as distribution of color is unbalanced.In addition,
The size of blue subpixels 12 is larger, and manufacture difficulty is smaller；And the size of red sub-pixel 13 and green sub-pixels 11 is smaller, system
It is larger to make difficulty.
The utility model embodiment provides a kind of pixel arrangement structure, display base plate and display device.The pixel arrangement knot
Structure passes through multiple minimum repetitive units for being arranged in array along line direction and column direction；Each minimum repetitive unit includes the first color
Sub-pixel, the second color sub-pixels and third color sub-pixels, the center of the first color sub-pixels and the second color sub-pixels
First line at center extends in a first direction, and the second of the center at the center and third color sub-pixels of the first color sub-pixels

The center of second colors sub-pixel and the center of third color sub-pixels are more symmetrical relative to the center of the first color sub-pixels, therefore
The symmetry of the pixel arrangement structure is more preferable, and display effect can be improved.
With reference to the accompanying drawing to pixel arrangement structure provided by the embodiment of the utility model, display base plate and display device into
Row explanation.
An embodiment of the present invention provides a kind of pixel arrangement structure.Fig. 3 A is to be mentioned according to an embodiment of the present invention
A kind of schematic diagram of the pixel arrangement structure supplied.As shown in Figure 3A, which includes being in along line direction and column direction
Multiple minimum repetitive units 110 of array arrangement.Each minimum repetitive unit 110 includes the first color sub-pixels 111, the second color
Sub-pixel 112 and third color sub-pixels 113；The center at the center of the first color sub-pixels 111 and the second color sub-pixels 112
The first line 121 extend in a first direction, the center of the first color sub-pixels 111 and the center of third color sub-pixels 113
The second line 122 extend in a second direction, first direction is perpendicular to second direction.It should be noted that the first above-mentioned face
The center at the center of sub-pixels, the center of the second color sub-pixels and third color sub-pixels refer to the first color sub-pixels,
The geometric center of second color sub-pixels and third color sub-pixels.In addition, above-mentioned line direction and column direction are that matrix is shown
Defined line direction and column direction.It is worth noting that, single along multiple minimum repetitions that line direction and column direction are arranged in array
Member can formation rule rectangle, other shapes can also be formed, this is not restricted for the utility model embodiment.
In pixel arrangement structure provided in this embodiment, the pixel arrangement structure is by by the first color sub-pixels,
Second colors sub-pixel and third color sub-pixels are arranged in both direction (first direction and second direction), so that
It only arranges in a pixel unit on one direction or second direction two sub-pixels, to can be improved using the pixel arrangement structure
Resolution ratio, and then can provide and a kind of there is true high-resolution display device.In addition, due to the first color sub-pixels
First line at center and the center of the second color sub-pixels extends in a first direction, the center of the first color sub-pixels and third
Second line at the center of color sub-pixels extends in a second direction, and first direction is perpendicular to second direction, therefore the second face
The center of sub-pixels and the center of third color sub-pixels are more symmetrical relative to the center of the first color sub-pixels, therefore the picture
The symmetry of plain arrangement architecture is more preferable, and display effect can be improved.
For example, in some instances, the above-mentioned translatable repeated arrangement of minimum repetitive unit is to form a complete picture
Plain arrangement architecture.It should be noted that not including the subelement of translatable repeated arrangement in minimum repetitive unit.In addition, at this
In utility model embodiment, above-mentioned minimum repetitive unit is a pixel, that is to say, that the first color sub-pixels, the second face
Sub-pixels and third color sub-pixels form a pixel.Significantly, since the manufacture craft of OLED product needs

Pixel arrangement structure provided by the embodiment of the utility model can substantially reduce the system of the OLED product using the pixel arrangement structure
Make cost, and improves the resolution ratio of the OLED product using the pixel arrangement structure.
For example, in some instances, the first color sub-pixels are green sub-pixels, the second color sub-pixels are the sub- picture of blue
Element, third color sub-pixels are red sub-pixel.Since human eye is more sensitive to green, when three sub- pictures of eye-observation RGB
It, can be using green sub-pixels as the center of pixel when the pixel of element composition.Therefore, when the center of green sub-pixels and red sub- picture
First line at the center of element extends in a first direction, second line at the center at the center and blue subpixels of green sub-pixels
Extend in a second direction, and when first direction is perpendicular to second direction, the center of red sub-pixel and the center of blue subpixels
Center relative to green sub-pixels is more symmetrical, so that red sub-pixel and blue subpixels be made to be distributed relative to green sub-pixels
It is more evenly distributed, display effect is more preferable.
For example, in some instances, as shown in Figure 3A, the length of the second color sub-pixels 112 in a second direction is greater than
The length of first color sub-pixels 111 in a second direction, the length of third color sub-pixels 113 in a first direction are greater than the
The length of one color sub-pixels 111 in a first direction.Fig. 3 B is another picture provided according to an embodiment of the present invention
The schematic diagram of plain arrangement architecture.Pixel arrangement structure shown in Fig. 3 B is identical as Fig. 3 A, in order to clearly show that shown in Fig. 3 B
The label of each structure in pixel arrangement structure is omitted in the positional relationship of each structure in pixel arrangement structure, Fig. 3 B.Such as figure
Shown in 3B, the first color sub-pixels are greater than in a second direction by the length of the second color sub-pixels of setting in a second direction

For example, in some instances, as shown in Figure 3A and Figure 3B, first direction is parallel with line direction, second direction and column
Direction is parallel.That is, first line at the center of the first color sub-pixels 111 and the center of the second color sub-pixels 112
121 extend along line direction, second line 122 at the center at the center and third color sub-pixels 113 of the first color sub-pixels 111
Extend along column direction.
For example, in some instances, as shown in Figure 3B, the length L2 of the length L1 of the first line 121 and the second line 122
It is equal.The distance between the center of first color sub-pixels and the center of the second color sub-pixels and the first color sub- picture as a result,
The distance between the plain center at center and third sub-pixel is equal.To can further improve the second color sub-pixels and third
Symmetry of the color sub-pixels about the first color sub-pixels, to improve the display effect of the pixel arrangement structure.It needs
Bright, when the equal length of the length of the first line and the second line, the second color sub-pixels and size or area can be with
The size or area of third color sub-pixels are different.For example, the second color sub-pixels width in a first direction and third face
The width of sub-pixels in a second direction can be adjusted as needed, to provide size or different the second color of area
Sub-pixel and third color sub-pixels.
For example, when the first color sub-pixels are green sub-pixels, the second color sub-pixels are red sub-pixel, third color
When sub-pixel is blue subpixels, since human eye is more sensitive to green, human eye can be using green sub-pixels as the center of pixel；
Therefore, when first line at the center of green sub-pixels and the center of red sub-pixel extends in a first direction, green sub-pixels
Center and second lines at center of blue subpixels extend in a second direction, and when first direction is perpendicular to second direction,
It can further improve red sub-pixel and blue by the way that the length of the length of the first line and the second line is configured identical

It is vertical with the second line 122, the 4th symmetry axis and third symmetry axis be mutually perpendicular to and with the second line 122 on the same line.
For example, in some instances, as shown in figs.3 a and 3b, the second color sub-pixels 112 are close to third color sub-pixels
113 while with third color sub-pixels 113 close to the second color sub-pixels 112 while be parallel to each other.Second color sub-pixels 112
Close to the first color sub-pixels 111 while with the first color sub-pixels 111 close to second color sub-pixels 112 while mutually put down
Row, third color sub-pixels 113 are close to the side of the first color sub-pixels 111 and the first color sub-pixels 111 close to third color
The side of sub-pixel 113 is parallel to each other.Can further improve as a result, in the case where craft precision is certain second color sub-pixels and
The area of third color sub-pixels, to can further improve the pixel arrangement structure to the producing level in space.
For example, in some instances, as shown in figs.3 a and 3b, the shape of the first color sub-pixels 111 can be square.When
So, the utility model embodiment includes but is not limited to this, and it is fillet that the shape of the first color sub-pixels, which can be square each apex angle,

For example, in some instances, as shown in figs.3 a and 3b, the first color sub-pixels 111, the second color sub-pixels 112
The shortest distance between third color sub-pixels 113 is equal.That is, the first color sub-pixels 111 and the second color
The shortest distance, the first color sub-pixels 111 between pixel 112 and the shortest distance between third color sub-pixels 113 and
The shortest distance between second colors sub-pixel 112 and third color sub-pixels 113 is equal, so as to maximally utilise technique
Precision.
For example, in some instances, as shown in figs.3 a and 3b, the shape and third color of the second color sub-pixels 112
The shape of pixel 113 is identical, and the shape of the second color sub-pixels 112 and the shape of third color sub-pixels 113 are about the first face
