Under such setting, the first area is a specific area on the display screen 100 dedicated to capturing images, while the second area is all used for displaying the screen of the electronic device. Certainly, the embodiment of the present application does not limit the layout manner of the first area and the second area, and optionally, the first area may be disposed on the edge of the second area. Meanwhile, the embodiment of the present application does not limit the specific area proportions of the first area and the second area on the display screen 100 .

In the embodiment of the present application, a first accommodating cavity C1 is configured in the display screen 100 , and the first accommodating cavity C1 can provide an accommodating space. The first accommodating cavity C1 is set corresponding to the first area, so that external light can be projected to the first accommodating cavity C1 after entering the display screen 100 through the first area. Optionally, the first region may be arranged opposite to the first accommodating cavity C1 . This kind of structural layout is relatively simple, easy to process, and facilitates direct projection of external light into the first accommodating cavity C1 . In another embodiment, the first accommodating cavity C1 may not be directly opposite to the first area. At this time, the electronic device may further include an optical path adjustment device, which can project light after passing through the first area of the display screen 100. To the optical path adjustment component, the optical path of the light is adjusted by the optical path adjustment component, and projected to the first accommodating cavity C1.

After the light passes through the lens module 210 , it can be projected onto the photosensitive element 220 , and the photosensitive element 220 processes the image.

It should be understood that, in electronic devices of the related art, the camera assembly 200 is stacked with the display screen 100, while the lens module 210 of the camera assembly 200 in the embodiment of the present application is integrated inside the display screen 100, and the display screen The space originally occupied by 100 has been reused, so that the overall space occupied by the camera assembly 200 and the display screen 100 can be undoubtedly reduced, thereby reducing the thickness parameters of the electronic device.

Wherein, the photosensitive element 220 can be selected as CCD (Charge Coupled Device, charge coupled device) or CMOS (Complementary Metal Oxide Semiconductor, complementary metal oxide semiconductor), and the embodiment of the present application does not limit its specific type.

It can be known from the above description that in the embodiment of the present application, the camera assembly 200 is set corresponding to the first area on the display screen 100 for the camera assembly 200 to collect image information. By constructing the first accommodating cavity C1 in the display screen 100, and setting the first accommodating cavity C1 corresponding to the first area, and setting the lens module 210 of the camera assembly 200 in the first accommodating cavity C1, here Under such a structural layout, the lens module 210 is equivalent to being integrated inside the display screen 100, thereby avoiding the complete overlapping of the camera assembly 200 and the display screen 100, thereby achieving the effect of reducing the thickness of the electronic device.

In the embodiment of the present application, there are various configurations of the first accommodating cavity C1, which are not limited in the embodiment of the present application.

As shown in Figure 1, in the first electronic device provided by the embodiment of the present application, the display screen 100 may include a cover plate 110, a polarizer 120, and a substrate 130 arranged in sequence, and the first accommodating cavity C1 may pass through the polarizer 120.

The polarizer 120 can play a polarizing role, which changes the polarization direction of the light, thereby ensuring that the display screen 100 can be developed to realize the display function. Under such a structural layout, the first accommodating cavity C1 is opened in the polarizer 120, that is, the polarizer 120 provides an accommodating space for the lens module 210, so that the lens module 210 is integrated inside the display screen 100, and further Realize the thinning of electronic equipment.

In the related art, the pole screen solution includes a multi-layer structure such as a cover plate 110, an adhesive layer, an upper glass layer, and a lower glass layer.
