Abstract

The disclosure provides a pixel structure, an array substrate and a display device. The pixel structure includes a reflection cup structure. Wherein, the pixel structure also includes a reflective island structure. The reflective island structure is protruded from the bottom of the reflective cup structure and located in the pixel opening of the reflective cup structure. Wherein, the side wall of the reflective island structure is spaced apart from the cup wall of the reflective cup structure. The present disclosure reduces the area of ​​the bottom of the reflective cup structure by adding a reflective island structure in the original pixel opening, that is, reduces 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. This can reduce the propagation loss from the waveguide to the reflective surface, and effectively improve the extraction efficiency of the reflective 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...
