Fig. 1 is a schematic structural diagram of a camera module according to an exemplary embodiment, and fig. 2 is a partial enlarged view of fig. 1, and an embodiment of the present disclosure provides a camera module 100 including: a display module 11, a backlight module 12, and a camera 13; the backlight assembly 12 and the camera 13 are positioned at the rear of the display assembly 11, the backlight assembly 12 is provided with an accommodating opening, and the front end of the camera 13 extends into the accommodating opening; be provided with shading glue film 14 between backlight unit 12 and the display module 11, backlight unit 12's rear is connected with support back frame 15, supports back frame 15 and to holding the trompil internal bending and form first extension face 151, and the laminating of first extension face 151 part is on the preceding terminal surface of camera 13, and shading glue film 14 bonds between first extension face 151 and display module 11.

Since the camera 13 is generally cylindrical, the accommodating opening formed in the backlight assembly 12 is a circular hole, and the diameter of the accommodating opening is slightly larger than that of the camera 13, so as to accommodate the camera 13. The lens of the camera 13 is disposed toward the display module 11, that is, the front end surface of the camera 13 is the plane where the lens is located, and in order to avoid interference between the camera 13 and the display module 11, a certain gap should be disposed between the front end surface of the camera 13 and the display module 11.

The backlight assembly 12 has a backlight source, a light guide plate, and the like, and is used for providing backlight, and in order to prevent light of the backlight assembly 12 from entering into a viewing angle region of the camera 13, a light-shielding adhesive layer 14 is provided for sealing and shielding light. In the related art, a rubber frame is generally disposed on the back supporting frame, the rubber frame is disposed between the backlight assembly and the back supporting frame, and the light-shielding rubber layer is adhered to the rubber frame, so that the light-shielding rubber layer plays a role of blocking the backlight assembly 12 and the camera 13.

The back support frame 15 is used for supporting and connecting the backlight assembly 12, and has a certain structural strength, and in order to avoid the increase of the volume and the visual black edge of the camera module 100, the back support frame 15 is generally made of a metal frame with high structural strength and a small volume, and optionally, the back support frame 15 is an iron frame.

In the embodiment of the present disclosure, a rubber frame is not required to be disposed, and the light-shielding rubber layer 14 is adhered to the supporting back frame 15, wherein one end of the supporting back frame 15 is fixedly connected to the rear of the backlight assembly 12, the other end of the supporting back frame 15 extends into the accommodating opening formed in the backlight assembly 12, and forms a first extending surface 151 attached to the front end surface of the camera 13, and the light-shielding rubber layer 14 is adhered to the first extending surface 151, and has the same adhering area and adhering effect as those of the related art.

The camera module 12 provided by the embodiment of the present disclosure bends to extend into the accommodating opening of the backlight assembly 12 through the support back frame 15, so that the first extending surface 151 of the support back frame 15 is attached to the front end surface of the camera 13, and the light-shielding adhesive layer 14 is adhered to the first extending surface 151, thereby effectively blocking the backlight assembly 12 and the camera 13, and having a good sealing and light-shielding effect. Moreover, compared with the related art, the design of the glue-free frame provided by the embodiment of the disclosure can effectively reduce the visual black edge of the camera module 12, and improve the user experience.

On the basis of the above embodiment, in this embodiment, the supporting back frame 15 further includes a second extending surface 152 and a third extending surface 153, the second extending surface 152 is fixedly connected with the backlight assembly 12, and the third extending surface 153 is used for connecting the first extending surface 151 and the second extending surface 152 and is located between the camera 13 and the backlight assembly 12.

The supporting back frame 15 is used for supporting the backlight assembly 12, and includes a second extending surface 152 fixedly connected to the backlight assembly 12, an extending direction of the second extending surface 152 is consistent with a plane where the backlight assembly 12 and the display assembly 11 are located, and the second extending surface 152 is a plane and is closely attached to the backlight assembly 12.

As can be seen from the above embodiments, the first extending surface 151 of the supporting back frame 15 is attached to the front end surface of the camera 13, and the front end surface of the camera 13 is parallel to the plane where the display module 11 and the backlight module 12 are located, so the second extending surface 152 and the first extending surface 151 are arranged in parallel.

In order to connect the first extending surface 151 and the second extending surface 152, so that the supporting back frame 15 forms an integral structure, a third extending surface 153 is further provided, and the shape of the third extending surface 153 is not limited, and the third extending surface may be a plane or a curved surface, and the extending direction thereof is not limited, so that the third extending surface does not interfere with the camera 13 and the backlight assembly 12.

In one possible embodiment, the third extending surface 153 is perpendicular to the plane of the display module 11. Since the second extension surface 152 and the first extension surface 151 are disposed in parallel, the third extension surface 153 is perpendicular to the first extension surface 151 and the second extension surface 152.

At this time, the cross section of the back support frame 12 is a zigzag line. The back frame 15 isolates the camera 13 from the backlight assembly 12, and the light-shielding adhesive layer 14 further shields light. As will be appreciated, since the camera head 13 is cylindrical as a whole, the back frame 15 is an annular cylindrical structure as a whole.

Referring to fig. 2, the third extending surface 153 and the camera 13 have a first avoidance gap a with a certain width therebetween. In order to avoid interference between the side surface of the camera 13 and the supporting back frame 12, a first avoidance gap a should be provided between the camera 13 and the third extending surface 153, the width of the first avoidance gap a is generally within 0.5 mm, and the specific value is determined according to factors such as the actual size of the camera 13 and the thickness of the supporting back frame 12.

Further, the width of the first extending surface 151 is greater than the width of the first avoiding gap a, and is greater than the minimum required width of the light-shielding adhesive layer 14 adhered to the first extending surface 151.

As can be seen from fig. 1 and 2, since the first extending surface 151 and the third extending surface 153 are perpendicular to each other and the first extending surface 151 needs to be attached to the front end surface of the camera 13 by a predetermined length, the width of the first extending surface 151 is larger than the width of the first relief gap a. Meanwhile, in order to avoid the first extended surface 151 from affecting the angle of view of the camera 13, the width of the first extended surface 151 cannot be too large.

In order to ensure the light shielding effect of the light shielding adhesive layer 14 and prevent light leakage, the width of the light shielding adhesive layer 14 adhered to the first extension surface 151 has a minimum required value, and the minimum required width is generally 0.4 mm. The light-shielding adhesive layer 14 may cover the whole area of the first extending surface 151, or leave a certain width margin, and therefore, the width of the first extending surface 151 should be larger than the minimum required width of the light-shielding adhesive layer 14 adhered on the first extending surface 151.

In one possible embodiment, the backlight assembly 12 includes: a light guide plate 121; a second avoiding gap B having a certain width is formed between the third extending surface 153 and the light guide plate 121, and the width of the second extending surface 152 is equal to the sum of the width of the second avoiding gap B and the width of the light guide plate 121. The backlight assembly 12 is used to provide a light source for the display assembly 11, and the backlight assembly 12 generally includes a backlight source, and light emitted from the backlight source is a linear light source, and needs to be converted into a surface light source by the light guide plate 121 to provide uniform light for the display assembly 11.

In order to avoid that the third extending surface 153 of the supporting back frame 15 is too close to the light guide plate 121, which affects the light emitting effect of the light guide plate 121, and even causes interference damage to the light guide plate 121, in this embodiment, a second avoiding gap B is provided between the third extending surface 153 and the light guide plate 121, the width of the second avoiding gap B is generally less than 0.5 mm, and the specific value is determined according to the actual width dimension of the light guide plate 121 and the thickness of the supporting back frame 15.

As can be seen from fig. 1 and 2, since the second extending surface 152 and the third extending surface 153 are perpendicular to each other, the width of the second extending surface 152 is equal to the sum of the width of the second escape gap B and the width of the light guide plate 121.

To sum up, in this embodiment, the size of the visual black border of the camera module 100 is equal to, first dodge clearance a, second dodge clearance B, support the thickness (the thickness of the third extension face 153) of back of the body frame 14 and the width sum of light guide plate 121, compare in the prior art and set up the scheme of gluing the frame between light guide plate 121 and support back of the body frame 15, the design of the frame that does not have of adoption in this embodiment, the visual black border that the width size of gluing the frame caused has been reduced, therefore the size of the visual black border that can significantly reduce, visual effect and experience have been improved.

Light emitted from the backlight source of the backlight module 12 enters the light guide plate 121 through the light incident surface on one side of the light guide plate 121, is reflected and diffused by the reflection sheet 122 and the diffusion sheet 125, then exits from the light exiting surface of the light guide plate 121, and finally forms a surface light source through the upper brightness enhancement film 123 and the lower brightness enhancement film 124 to be provided to the display module 11.

The light guide plate 121, the reflective sheet 122, the upper brightness enhancement film 123, the lower brightness enhancement film 124 and the diffusion sheet 125 are stacked and closely attached to each other, thereby forming the whole backlight assembly 12. The width dimensions of the reflective sheet 122, the upper brightness enhancement film 123, the lower brightness enhancement film 124 and the diffusion sheet 125 are similar to the width dimension of the light guide plate 121, so as to ensure that the backlight assembly 12 does not interfere with the third extending surface 153 of the supporting back frame 15.

Further, the display assembly 11 includes a cover glass 111 and a liquid crystal display panel, the cover glass 111 is bonded to the liquid crystal display panel; the liquid crystal display panel includes an upper polarizer 112, a color filter substrate 113, an array substrate 114, and a lower polarizer 115, which are sequentially stacked.

The cover glass 111 plays a role in protecting the liquid crystal display panel, and the liquid crystal display panel is used for realizing liquid crystal display. Since the cover glass 111 and the liquid crystal display panel are transparent structures, the image pickup function of the camera 13 is not affected. In order to avoid the influence of the upper polarizer 112 and the lower polarizer 115 on the light rays taken by the camera 13, circular openings are required to be formed in the upper polarizer 112 and the lower polarizer 115 within the field angle range of the camera 13.
