Display substrate, display panel and display device

Abstract

The invention discloses a display substrate, a display panel and a display device. The display substrate comprises a plurality of first pixel group rows and a plurality of second pixel group rows; thefirst pixel group rows and the second pixel group rows are arranged alternately; the first pixel group rows and the second pixel group rows extend in a first direction; the first pixel group row comprises a plurality of first sub-pixel groups and a plurality of second sub-pixel groups; the first sub-pixel groups and the second sub-pixel groups are alternately arranged; the second pixel group rowcomprises a plurality of third sub-pixel groups; the third sub-pixel group, the first sub-pixel group and the second sub-pixel group are arranged in a staggered manner; and the structures of the firstsub-pixel group, the second sub-pixel group and the third sub-pixel group are a first structure, a second structure or a third structure. According to the display substrate provided by the embodimentof the invention, the distance between the sub-pixel groups with the same color can be increased, the color mixing risk during evaporation is reduced, the aperture opening ratio of the display substrate is improved, and the color edge problem of the display substrate is avoided.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of display panels, and in particular, to a display substrate, a display panel, and a display device. Background technique [0002] In the field of flat panel display technology, Organic Light-Emitting Diode (OLED) has the advantages of light weight, fast response, wide viewing angle, rich colors and high brightness, low power consumption and flexibility. According to the display driving method, OLED can be divided into passive driving OLED (Passive Matrix OLED, PMOLED) and active driving OLED (Active Matrix OLED, AMOLED). Limited by the driving mode, the PMOLED has a short lifespan and cannot achieve a large area. Therefore, under the trend of increasingly pursuing large size and high resolution in the field of display panel technology, AMOLED has become an important development direction of display technology.

AI Technical Summary

Problems solved by technology

During the evaporation process of organic materials, the mask produced according to the existing pixel arrangement structure has a high risk of color mixing when evaporating pixel unit 1 due to the small distance between the openings of different masks. The aperture ratio of the obtained display panel is low, and there is a problem of color fringing
