Abstract

The embodiment of the invention discloses a display panel and a display device, a display area of the display panel is provided with a camera shooting area and a non-camera shooting area, and in the display area, the light emitting side of the display panel is provided with an optical coupling layer; and the thickness of the optical coupling layer in the camera shooting area is greater than that of the optical coupling layer in the non-camera shooting area, so that the brightness attenuation of the display area is consistent. According to the display panel and the display device, the brightness attenuation difference between the non-camera shooting area and the camera shooting area can be relieved, and the visual angle difference is reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] The camera technology under the screen is a major technological hotspot in the display of mobile phones in the future. Under-screen camera technology refers to hiding the camera under a certain area of ​​the display screen (hereinafter referred to as the area of ​​the camera). The role of the transparent area, the non-camera area (the area of ​​the display screen other than 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 problems. [0003] For example, in order to realize the under-screen camera technology, the pixel design of the camera area is different from that of the non-camera area. This difference often results in changes in the viewing angle characteristics of the screen...
