Title:
LIGHT-EMITTING DIODE DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/035401
Kind Code:
A1
Abstract:
A light-emitting diode display panel and a manufacturing method therefor, and an organic light-emitting diode display apparatus. The light-emitting diode display panel comprises: a base substrate (600), a plurality of sub-pixels located on the base substrate (600), a color resist layer, and a light blocking structure. The base substrate (600) comprises a display region (101) and a peripheral region (102); the plurality of sub-pixels are located in the display region (101); and the light blocking structure is located in the peripheral region (102), and is of an annular structure surrounding the plurality of sub-pixels. The light blocking structure comprises a first light blocking structure (220) and a second light blocking structure (320); the second light blocking structure (320) is located on one side, away from the base substrate (600), of the first light blocking structure (220); a second orthographic projection, on the base substrate (600), of the second light blocking structure (320) is located in a first orthographic projection, on the base substrate (600), of the first light blocking structure (220), and the first orthographic projection and the second orthographic projection do not completely overlap. A size relationship between the second light blocking structure (320) and the first light blocking structure (220) is adjusted to form a stepped structure, so as to improve the uniformity of the color resist layer formed in the display region (101) to prevent a phenomenon of non-uniform display.
