Title:
DISPLAY SUBSTRATE AND MANUFACTURING METHOD THEREFOR, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/000459
Kind Code:
A1
Abstract:
A display substrate, comprising a display area (100) and a cathode ring area (300); and further comprising an insulation layer (15) and a light-emitting structure layer (20), which are sequentially arranged on a base (10). The light-emitting structure layer (20) comprises an anode layer, a pixel definition layer, a light-emitting layer, and a cathode (35), wherein the anode layer comprises a display anode (31A), which is located in the display area (100), and a cathode voltage line (32), which is located in the cathode ring area (300); and the cathode (35) is connected to the cathode voltage line (32), which comprises first cathode voltage lines (320) and second cathode voltage lines (321), the first cathode voltage lines (320) extending in a first direction (X), the second cathode voltage lines (321) extending in a second direction (Y), the first direction (X) being a direction parallel to an edge of the display substrate, and at least one second cathode voltage line (321) being arranged between two adjacent first cathode voltage lines (320) and being connected to the two adjacent first cathode voltage lines (320).
