Document Type and Number:
WIPO Patent Application WO/2022/205405
Kind Code:
A1
Abstract:
The present disclosure provides a display substrate and a preparation method therefor. The display substrate comprises a base substrate and a pixel circuit layer which is formed on the base substrate; the pixel circuit layer comprises a plurality of pixel driving circuits, and the plurality of pixel driving circuits are arranged in an array along a first direction and a second direction, the first direction being perpendicular to the second direction; the base substrate is provided with grooves extending along the first direction, the grooves having bottom surfaces and side surfaces; a surface of the base substrate comprises the bottom surfaces and the side surfaces of the grooves, and top surfaces between adjacent grooves; the bottom surfaces of the grooves are substantively parallel to the top surfaces between the adjacent grooves; a first angle is formed between the side surfaces of the grooves and the bottom surfaces of the grooves and the top surface between adjacent grooves; and a part of each pixel driving circuit is formed on the side surfaces of the grooves.
