detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

The terminal device 10 includes, but is not limited to, electronic terminals such as mobile phones and tablet computers. As shown in FIG. 1 , a terminal device 10 includes a housing 11 , and a motherboard and a display module are accommodated in the housing 11 . Wherein, the shell 11 may be a part of the shell of the terminal device 10, such as a rear shell. The display module is used to present images, and may also have a touch function. The display module includes a display screen 12 . The display screen 12 includes, but is not limited to, a liquid crystal display screen, an organic light-emitting diode display screen, or an electronic ink screen and other display elements with electronic display functions. The display screen 12 includes an effective display area A, and the effective display area A is the area where the display screen 12 can display pictures. The area within the dashed box in FIG. 1 is the effective display area A.

A receiving hole (to be described below) is provided in the effective display area A, and the camera assembly 13 is received in the receiving hole. Both the display screen 12 and the camera assembly 13 are electrically connected to the main board.

In the prior art, the camera assembly is arranged outside the effective display area of the display screen. This design reduces the proportion of the effective display area to the display area, that is, reduces the screen-to-body ratio and weakens the user experience; in order to arrange the camera components, the non-display area on the display screen except the effective display area needs to be reserved. Enough structure space, after the size of these non-display areas increases, it will be unfavorable for human hands to hold. However, in the solution of this embodiment, the camera assembly is directly arranged in the effective display area, without reserving an additional non-display area for the camera assembly, so that the size of the effective display area can be enlarged, thereby increasing the screen-to-body ratio of the display screen; On the other hand, since the size of the non-display area can be reduced, the total size of the display screen can be effectively reduced, making it easy for users to hold and improve user experience; the camera assembly can be housed in the storage hole, and the inside of the display screen can be utilized The structural space does not increase the thickness of the display screen, so that the overall thickness of the terminal equipment will not be increased.

In this embodiment, the display module may also include functional devices with other functions. The functional device is a single component or a combination of components used to realize specific functions, such as audio input and output, image acquisition, distance sensing, light intensity sensing and other functions. For example, the functional device may be an earpiece assembly using bone conduction technology, and the earpiece assembly is arranged under the display screen 12 and located in the effective display area A. The use of the bone conduction earpiece does not need to open a sound hole in the effective display area A, so that the image display in the effective display area A is not affected while sound conduction is realized.

FIG. 2 is intended to illustrate the multi-layer structure of the display screen 12 , and the assembly relationship of the display screen 12 , the main board 14 , and the housing 11 . As shown in 2, the display screen 12 includes a plurality of stacked functional layers, such as the functional layer 122 to the functional layer 126, and the functional layers 122 to 126 work together to form an effective display area A.

The functional layers 122 to 126 are all accommodated in the housing 11 , and some of the functional layers 122 to 126 are electrically connected to the main board 14 . Functional layer 122～functional layer 126 shown in Fig. 2 are all on the main board 14, and this is only a kind of illustration; According to the actual situation, the relative installation position of main board 14 relative to functional layer 122～functional layer 126 can be adjusted, in order to suit Meet the structural design requirements of the terminal device 10. The number of functional layers can be set according to actual needs, and is not limited to that shown in FIG. 2 .

Specifically, the functional layer is a film-shaped or plate-shaped structure including various electronic components, mechanical components, and/or optical components to realize specific circuit functions. When the display screen 12 is a liquid crystal display screen, the functional layer also includes a liquid crystal layer.

One end of the receiving hole 122h passes through the first polarizing layer 122 in a direction away from the other functional layers, that is, in a direction away from the thin film transistor array layer 123 , the liquid crystal layer 124 , the color filter unit array layer 125 and the second polarizing layer 126 . The receiving hole 122h may pass through the entire first polarizing layer 122 , or may only pass through a part of the first polarizing layer 122 . In the latter case, one end (the lower end in FIG. 3 ) of the receiving hole 122h is located within the surface (the lower surface in FIG. 3 ) of the first polarizing layer 122 . The receiving hole 122h is not limited to be a circular hole, a rectangular hole or other suitable shapes. The camera assembly 13 is accommodated in the receiving hole 122h, and can be electrically connected to the main board 14 through a certain functional layer in the display screen 12 . For example, the electrodes on the thin film transistor array layer 123 under the first polarizing layer 122 are connected to the main board 14 . In this embodiment, only one functional layer of the first polarizing layer 122 is provided with the receiving hole, and one end of the receiving hole penetrates to the outer surface of the display screen 12, that is, the receiving hole penetrates through the first polarizing layer.

One end of the opening 124h passes through the thin film transistor array layer 123 and the first polarizing layer 122 , and the opposite end is connected to the isolation tube 1241 and communicated with it. In this embodiment, the opening 124h and the inner hole of the isolation tube 1241 jointly form the receiving hole of the camera module 13, which is equivalent to the three functional layers of the first polarizing layer 122, the thin film transistor array layer 123 and the liquid crystal layer 124. There is the receiving hole, and one end of the receiving hole penetrates to the outer surface of the display screen 12 .

However, the difference is that the opposite ends of the isolation cylinder 1241 are communicated with openings 126h. One of the openings 126h passes through the TFT array layer 123 and the first polarizing layer 122 , and the other opening 126h passes through the color filter unit array layer 125 and the second polarizing layer 126 . The two openings 126h and the inner hole of the isolation cylinder 1241 jointly form the receiving hole. In this embodiment, the five functional layers corresponding to the first polarizing layer 122, the thin film transistor array layer 123, the liquid crystal layer 124, the color filter unit array layer 125 and the second polarizing layer 126 are all provided with the accommodation holes, and Both ends of the receiving hole penetrate to the outer surface of the display screen 12 .
