Problems solved by technology
In the prior art, the method of reducing the pixel points of the display area or reducing the area of the display pixels is often used to increase the light transmittance of the display panel, but these two methods are difficult to reduce the area of the lower light-shielding layer, which may easily cause the light transmittance of the display panel to decrease. Insufficient, which affects the quality of light received by the camera light camera photosensitive element

The invention provides a display panel and an under-screen camera shooting display device, the display panel comprises a first display area and a photosensitive area, and the photosensitive area comprises a second display area and a light hole area; the first display area surrounds the second display area, and the second display area surrounds the light hole area; the display panel in the photosensitive area further comprises a substrate; a driving transistor layer formed on the substrate; the driving transistor layer comprises a composite insulating layer; a flat layer formed on the driving transistor layer; the light-emitting sub-pixel unit comprises a pixel definition layer; the pixel definition layer is formed on the flat layer; the composite insulating layer located in the light hole area is provided with a light hole, a part of the substrate is exposed out of the light hole, and a part of the flat layer and a part of the pixel definition layer are filled in the light hole. According to the display panel and the under-screen camera shooting display device, the area of the light shielding layer can be reduced, and high light transmittance is achieved.
Description
technical field [0001] The present application relates to the technical field of under-screen imaging, and in particular to a display panel and an under-screen imaging and display device. Background technique [0002] With the continuous advancement of technology and the continuous upgrading of mobile phones, people's requirements for mobile phone screens are also getting higher and higher. At present, most of the mobile phones on the market are hole-digging screens. However, there are many technical problems in the hole-digging screens, such as difficult packaging and cumbersome processes. Mobile phone screen manufacturers around the world are making every effort to develop full screens. This is because full screen phones can not only improve the appearance of the phone, make the phone more technological, but also accommodate a larger screen and enhance the visual experience. However, the full-screen technology still faces difficulties in the design and manufacturing proce...
