Problems solved by technology

[0002] At present, since polarizers will significantly reduce the light output rate of transparent display devices, generally speaking, transparent display devices will not have polarizers. However, since transparent display devices do not include polarizers, the reflectivity of transparent display devices to ambient light Higher, higher reflectivity to ambient light will lead to lower contrast when transparent display devices display
[0003] Therefore, it is necessary to propose a technical solution to solve the problem of reduced contrast caused by the high reflectivity of the transparent display device to ambient light

Abstract

The invention discloses a display device which is provided with a display light-transmitting area, the display light-transmitting area comprises a plurality of light-transmitting areas and a plurality of light-emitting areas, and the light-emitting areas and the light-transmitting areas are arranged at intervals. The pixel array layer is arranged on the substrate, and the pixel array layer comprises a metal structure located in the area, except the multiple light-transmitting areas, in the display light-transmitting area; the light absorption layer is arranged on the side, away from the substrate, of the pixel array layer, and the light absorption layer comprises a first opening which penetrates through the light absorption layer in the thickness direction of the display device and is overlapped with the light transmitting area; the second opening penetrates through the light absorption layer in the thickness direction of the display device and is overlapped with the light emitting region; and a light absorbing structure overlapping at least a portion of the metal structure.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display device. Background technique [0002] At present, since the polarizer will significantly reduce the light extraction rate of the transparent display device, in general, the transparent display device will not have the polarizer. However, since the transparent display device does not include the polarizer, the reflectivity of the transparent display device to ambient light is caused. The higher the reflectivity of ambient light, the lower the contrast ratio of the transparent display device. [0003] Therefore, it is necessary to propose a technical solution to solve the problem of reduced contrast ratio caused by the high reflectivity of the transparent display device to ambient light. SUMMARY OF THE INVENTION [0004] The purpose of the present application is to provide a display device to reduce the reflectivity of the display device to ambient ligh...
