In order to increase the screen ratio of terminal devices, more and more terminal devices place cameras below the display screen to form an under-screen camera. In order to ensure the normal shooting of the camera, the display screen needs to have a transparent area.

Considering the shooting angle of the camera and the assembly tolerance of the display screen, the size of the transparent area opened on the display screen is larger. Obviously, the larger size of the transparent area leads to a larger non-display area of the display screen. Furthermore, it is contrary to the original intention of increasing the proportion of the screen of the terminal device to increase the proportion of the display area. In the current terminal equipment, the camera is fixed on the face shell of the housing through a camera bracket, and the light-transmitting area of the display screen is relatively large, which in turn leads to poor display performance of the terminal equipment.

Detailed ways

In order to make the objectives, technical solutions, and advantages of the present disclosure clearer, the technical solutions of the present disclosure will be described clearly and completely in conjunction with specific embodiments of the present disclosure and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present disclosure.

The technical solutions disclosed in each embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings.

Please refer to FIG. 1 to FIG. 4, an embodiment of the present disclosure discloses a terminal device. The disclosed terminal device includes a housing 100, a display screen 200 and a camera 300.

The housing 100 is a basic component of the terminal device, and the housing 100 can provide an installation foundation for other components of the terminal device. The display screen 200 is arranged on the housing 100, and the camera 300 is arranged in an inner cavity formed by the display screen 200 and the housing 100, thereby achieving installation. Generally, the display screen 200 is usually fixed to the housing 100 by bonding.

In the embodiment of the present disclosure, the housing 100 includes a face shell 110, and the display screen 200 is disposed on the face shell 110. Specifically, the display screen 200 is adhered to the face shell 110 to achieve a fixed connection with the face shell 110. .

The display screen 200 is a display component of the terminal device. In the embodiment of the present disclosure, the display screen 200 includes a light-transmitting area 200a, and the light-transmitting area 200a can provide conditions for the camera 300 to shoot.

The camera 300 is arranged opposite to the light-transmitting area 200a. In a specific work process, since the camera 300 is arranged opposite to the light-transmitting area 200a, it can sense the ambient light passing through the light-transmitting area 200a, so that the camera 300 can finally pass through the light-transmitting area 200a. Realize image shooting.

In the embodiment of the present disclosure, the camera 300 is bonded and fixed to the cover 110, so that the camera 300 is installed in the cavity formed by the housing 100 and the display screen 200. Specifically, the camera 300 may be directly connected to the face shell 110 through adhesive media such as glue dispensing or double-sided tape.

In an embodiment of the present disclosure, the display screen 200 includes a display layer 210 and a transparent cover 220 covering the display layer 210. The display layer 210 is the main part of the display screen 200, and the light-transmitting cover 220 covers the display layer 210, so as to provide protection for the display layer 210. The transparent cover 220 may be a glass cover or a resin cover. The transparent cover 220 is usually bonded and fixed to the display layer 210 through an optical adhesive layer 240.

As shown in FIG. 1, the size A of the first area of the light-transmitting area 200a can ensure that the camera 300 takes pictures under the set angle of view; the size B of the second area of the light-transmitting area 200a is the assembly error of the display screen 200, The second area is arranged around the first area, so the size of the light-transmitting area 200a is C=A+2B. We know that under the premise of setting the shooting angle of view of the camera 300, the smaller the distance D between the camera 300 and the transparent cover 220 of the display screen 200, the smaller the size A of the first area of the transparent area 200a, and vice versa. When the distance D between the camera 300 and the transparent cover 220 of the display screen 200 is greater, the size A of the first area of the transparent area 200a is larger. Since the size B of the assembly error is determined, the size of the light-transmitting area 200a depends on the size A of the first area, and indirectly depends on the distance D between the camera 300 and the light-transmitting cover 220 of the display screen 200.

Compared with the background art that the camera is fixed on the face shell through the camera bracket, in the terminal device disclosed in the embodiments of the present disclosure, the camera 300 is directly bonded to the face shell 110, thereby preventing the camera bracket from interfering with the camera 300 and transmitting light. The influence of the distance between the cover plates 220 can in turn make the distance between the camera 300 and the transparent cover plate 220 smaller. Under the premise that the shooting angle of view of the camera 300 is the same, the camera 300 needs a smaller light-transmitting area when shooting. In this case, the display screen 200 does not need to provide a larger light-transmitting area. In turn, the area of the display area of the display screen 200 can be increased, and ultimately the screen occupying ratio of the terminal device can be increased.

At the same time, the camera 300 is directly fixed on the face shell 110 by bonding. Compared with the related art where a camera bracket is also provided between the camera 300 and the face shell 110, the terminal device disclosed in the embodiment of the present disclosure is undoubtedly The assembly error of the camera 300 can be reduced, which is beneficial to achieve a more accurate installation of the camera 300.

The camera 300 includes a lens 310, and the cover 110 needs to avoid the lens 310 so as not to affect the normal shooting of the camera 300.

The camera body 320 may include a connecting surface 321 surrounding the lens 310, and the connecting surface 321 is bonded to the inner surface of the cover 110 Fixed, the connection method of this structure can make full use of the structure of the camera 300 itself, which is beneficial for the lens 310 to be closer to the transparent cover 220. Specifically, the connecting surface 321 and the surface shell 110 may be bonded by an adhesive layer 400.

The connecting surface 321 of the above structure can undoubtedly improve the stability of the connection between the camera 300 and the display screen 200, and at the same time, it is also conducive to sealing the space where the lens 310 is located through the adhesive layer 400, so as to avoid the intrusion of foreign objects in the space where the lens 310 is located. For example, dust and liquid), which can avoid the adverse effects of these foreign objects on shooting.
