Abstract

The embodiment of the present application discloses a display panel and a display device, wherein a display area of ​​the display panel has an imaging area and a non-photographic area, and in the display area, a light coupling layer is provided on the light-emitting side of the display panel; wherein The thickness of the light coupling layer in the imaging area is greater than the thickness of the light coupling layer in the non-imaging area, so that the luminance attenuation of the display area is uniform. The display panel and the display device of the present application can alleviate the difference in luminance attenuation between the non-photographic area and the imaging area, so that the difference in viewing angle can be reduced.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] Under-screen camera technology is a major technology hotspot for future mobile phone displays. Under-screen camera technology refers to hiding the camera under a certain area of ​​the display screen (hereinafter referred to as the camera area). The role of the transparent area, the non-camera area (the area of ​​the display screen except the camera area) can be displayed normally. The realization of this technology can greatly increase the screen ratio, but at the same time, there are also great technical difficulties. [0003] For example, in order to realize the under-screen camera technology, the pixel design of the camera area is different from the pixel design of the non-camera area. This difference often results in a change in the viewing angle characteristics of the screen. For example,...
