Abstract

The invention provides a pixel structure, an array substrate and a display device. The pixel structure comprises a reflection cup structure. The pixel structure further comprises a reflection island structure. The reflection island structure is arranged at the cup bottom of a reflection cup structure in a protruding mode and located in a pixel opening of the reflection cup structure. A side wall of the reflection island structure is separated from the cup wall of the reflection cup structure. According to the invention, the reflection island structure is added in the original pixel opening; the area of the bottom of the reflection cup structure is reduced, i.e., reducing the area of the light-emitting area of the pixel structure, thereby increasing the perimeter area ratio of the light-emitting area of the pixel structure, reducing the transmission loss of waveguide transmission to a reflection surface, and effectively improving the extraction efficiency of the reflection cup structure.

Description

technical field [0001] The present disclosure relates to the technical field of semiconductor displays, and in particular to a pixel structure, an array substrate and a display device. Background technique [0002] The reflective cup structure is widely used as a common design form of the pixel structure in the existing display devices. Due to the limitation of the process, the extraction efficiency of the reflective cup structure of the existing pixel structure is low. Contents of the invention [0003] A main purpose of the present disclosure is to overcome at least one defect of the above-mentioned prior art, and provide a pixel structure with a relatively large perimeter area of ​​the light emitting region. [0004] Another main purpose of the present disclosure is to overcome at least one defect of the above-mentioned prior art, and provide an array substrate having the above-mentioned pixel structure. [0005] Another main purpose of the present disclosure is to ov...
