The screen camera technology can realize full screen display on the premise of not damaging the integrity of a screen. The screen display area is divided into two parts: a conventional display area and an off-screen camera area. When the camera is closed, the camera area under the screen is used for displaying pictures, and full screen display is realized. And when the camera is started, the camera shooting function is realized. The under-screen camera area is different from a conventional display area, and the adopted liquid crystal type belongs to scattering liquid crystal and can perform transparent display. Under normal conditions, light passing through the liquid crystal layer is scattered by the liquid crystal layer, and the light passing through the display is reduced, so that the display is in a scattered fog state. Haze is an important parameter for measuring the transparency characteristic of transparent or semitransparent materials, and generally, the larger the optical path, the more obvious the effect of scattering light by liquid crystal, and the better the haze effect. The conversion of the scattered fog state and the transmitted transparent state can be realized through controlling the voltage. When the camera area under the screen is used for displaying pictures, the larger the contrast ratio between the transparent state and the fog state is, the better the display effect is. The haze is adjusted by controlling the transmittance of light rays in the foggy state of the camera area under the screen, the contrast is adjusted, and a better display effect of a picture can be realized.
However, the thickness of the liquid crystal layer in the under-screen camera area of the existing display panel is about three microns, and the haze is poor, so that the contrast is poor, and the display effect of the picture is also poor.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Referring to fig. 1, a display panel 100 is provided in a first embodiment of the present invention, and includes a display area 11 and an off-screen camera area 12. The display area 11 is a conventional display area 111, the under-screen camera area 12 is a transparent display area, and a camera hole 121 is formed in the middle of the under-screen camera area 12.
Referring to fig. 2, which is a cross-sectional view of the display panel 100 at a-a in fig. 1, the display panel 100 includes an array substrate 10, a liquid crystal layer 20, and a color film substrate 30. The liquid crystal layer 20 is arranged on the array substrate 10; the thickness of the liquid crystal layer 20 in the under-screen camera area 12 is 4um to 5um, preferably 5 um; the color film substrate 30 is disposed on the liquid crystal layer 20 and opposite to the array substrate 10.
The liquid crystal layer 20 in the display region 11 uses a conventional liquid crystal; the liquid crystal layer 20 in the under-screen camera area 12 uses scattering liquid crystal, and when light passes through the liquid crystal layer 20, the light is scattered by the liquid crystal layer 20, and the transmitted light is reduced, so that the under-screen camera area 12 is in a scattering fog state. The thickness of the liquid crystal layer 20 in the display area 11 is about three micrometers, and if the structure of the array substrate 10 in the under-screen camera area 12 is not changed, the thickness of the under-screen camera area 12 is also about three micrometers, which makes it difficult to increase the haze. Haze is an important parameter for measuring the transparency characteristic of transparent or semitransparent materials, and generally, the larger the optical path, the more obvious the effect of scattering light by liquid crystal, and the better the haze effect. In order to increase the haze effect of the liquid crystal layer 20 in the scattering state in the under-screen camera area 12, the grooves 31 are arranged to increase the optical path length to increase the scattering degree, so as to increase the haze effect, thereby improving the contrast of the under-screen camera area 12 and enhancing the image display effect of the under-screen camera area 12.
Referring to fig. 2, in the present embodiment, the display panel 100 further includes a camera sensor 40, and the camera sensor 40 is disposed corresponding to the off-screen camera area 12. When the camera sensor 40 is turned off, the under-screen camera area 12 is used for displaying pictures, so that full-screen display is realized; when the camera sensor 40 is turned on, the under-screen camera area 12 is in a transparent display mode, so that a camera shooting function is realized.
The display panel 100 of the present invention is suitable for various occasions and can be combined with various devices and structures, and the display panel 100 may be a mobile terminal, such as a mobile phone, an intelligent wearable device, or a fixed terminal (PC), or other devices with a display function, such as a tablet PC, a television, a display window, etc. It is to be understood that the display panel 100 of the present invention is provided with other devices, structures, etc. not shown in this specification in order to realize functions.
Referring to fig. 3, the array substrate 10 includes a substrate 1, a driving circuit layer 2, a planarization layer 3, a common electrode layer 4, an insulating layer 5, and a pixel electrode layer 6, which are sequentially stacked from bottom to top. Specifically, the driving circuit layer 2 is provided on the substrate 1; the flat layer 3 is arranged on the driving circuit layer 2; the flat layer 3 is provided with a groove 31 in the under-screen camera area 12; the common electrode layer 4 is arranged on the flat layer 3; the insulating layer 5 is arranged on the common electrode layer 4; the pixel electrode layer 6 is disposed on the insulating layer 5.
In this embodiment, the groove 31 is formed in the flat layer 3 located in the under-screen camera area 12, so that the thickness of the liquid crystal layer of the display panel formed by the array substrate 10 in the under-screen camera area 12 is increased from about three micrometers to about five micrometers, the optical path of light passing through the liquid crystal layer is increased, and the light scattering effect is improved; haze is an important parameter for measuring the transparent characteristic of a transparent or semitransparent material, and generally, the larger the optical path is, the more obvious the effect of scattering light by liquid crystal is, and the better the haze effect is; in the embodiment, the optical path of the light passing through the liquid crystal layer is increased, so that the haze of the liquid crystal layer is increased, and the technical problem that the haze of the under-screen camera area 12 is low is solved, so that the contrast of the under-screen camera area 12 is improved, and the picture display effect of the under-screen camera area 12 is enhanced.
In this embodiment, the distribution range of the grooves 31 is the same as the distribution range of the under-screen camera area 12. Namely, the groove 31 is a groove in the lower camera area 12, which is obtained by removing the whole of the planarization layer 3, compared with the whole of the array substrate 10, so that the thickness of the lower camera area 12 can be reduced to the maximum extent compared with the thickness of the display area 11, and thus the thickness of the liquid crystal layer of the display panel formed by the array substrate 10 in the lower camera area 12 is increased.
In this embodiment, the depth of the groove 31 is equal to the thickness of the planarization layer 3. This enables the flat layer 3 to be removed entirely from the flat layer 3 in the under-screen camera area 12.
In this embodiment, the depth of the groove 31 is 1um-2 um. Typically the thickness of the flat layer 3 is 1um-2um and the depth of the recess 31 is dimensioned such that the entire flat layer 3 is removed in the under-screen camera area 12.

Namely, the groove 31 is a groove in the lower camera area 12, which is obtained by removing the whole of the planarization layer 3, compared with the whole of the array substrate 10, so that the thickness of the lower camera area 12 can be reduced to the maximum extent compared with the thickness of the display area 11, and thus the thickness of the liquid crystal layer of the display panel formed by the array substrate 10 in the lower camera area 12 is increased.
In this embodiment, the depth of the groove 31 is equal to the thickness of the flat layer 3; the depth of the groove 31 is 1um-2 um. Typically the thickness of the flat layer 3 is 1um-2um and the depth of the recess 31 is dimensioned such that the entire flat layer 3 is removed in the under-screen camera area 12.
