Title:
DISPLAY SUBSTRATE AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/207480
Kind Code:
A9
Abstract:
A display substrate and a display device. The display substrate comprises a base substrate (100) and multiple pixels (200) located on the base substrate (100). Each pixel (200) comprises multiple sub-pixels (20), the multiple sub-pixels (20) comprising a first color sub-pixel (210), a second color sub-pixel (220), and a third color sub-pixel (230). A light-emitting area (020) of one pixel (200) is located in a virtual graph (300). Light-emitting areas (020) of different pixels (200) are located in different virtual graphs (300). Adjacent virtual graphs (300) where light-emitting areas (020) of adjacent pixels (200) are located do not overlap with each other. The virtual graph (300) comprises a circle or an oval, the ratio of the long axis to the short axis of the oval being 1.3 to 1.01. In each of the at least one pixel (200), the light-emitting area of the second color sub-pixel (220) surrounds at least part of the light-emitting area of the first color sub-pixel (210). According to the embodiments of the present disclosure, the light-emitting area of each pixel is arranged in the circle- or oval-shaped virtual graph to reduce the graininess and jaggedness of display and mitigate color cast.
