Title:
DISPLAY SUBSTRATE, MANUFACTURING METHOD THEREFOR, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/142055
Kind Code:
A1
Abstract:
Provided in the present disclosure are a display substrate, a manufacturing method therefor, and a display apparatus. The display substrate comprises a substrate, a plurality of sub-pixels, a plurality of gate lines, and a plurality of first compensation gate patterns, the plurality of sub-pixels, the plurality of gate lines, and the plurality of first compensation gate patterns being arranged on the substrate. Each sub-pixel comprises a sub-pixel driving circuit, which comprises a compensation transistor. Each compensation transistor comprises a second compensation gate pattern, each first compensation gate pattern being located between the corresponding second compensation gate pattern and the substrate. The first compensation gate patterns are coupled to a direct-current signal output end. Each second compensation gate pattern is coupled to the corresponding gate line. Each compensation transistor comprises a compensation active layer, which is located between the corresponding first compensation gate pattern and the corresponding second compensation gate pattern and comprises a compensation channel part. The orthographic projection of each first compensation gate pattern on the substrate at least overlaps the orthographic projection of the corresponding compensation channel part on the substrate. The orthographic projection of each second compensation gate pattern on the substrate covers the orthographic projection of the corresponding compensation channel part on the substrate.
