Title:
DISPLAY SUBSTRATE, DISPLAY APPARATUS, AND DRIVING METHOD FOR DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/222446
Kind Code:
A1
Abstract:
Provided in the present disclosure are a display substrate, a display apparatus, and a driving method for a display apparatus. The display substrate comprises a base, a driving circuit layer, which is formed on the base, a light-emitting unit, which is located on the side of the driving circuit layer that is away from the base, and a light transmission layer, which is located on the side of the light-emitting unit that is away from the base, wherein the light-emitting unit comprises a first electrode layer, a light-emitting layer and a second electrode layer, which are successively arranged in a stacked manner; the second electrode layer comprises a plurality of second electrode patterns, which are independent of one another and are arranged in an insulated manner; and at least some of the second electrode patterns are connected to different common voltage ends. In the embodiments of the present disclosure, second electrode patterns, which are independent of one another and are arranged in an insulated manner, are provided, such that common voltages corresponding to different light-emitting units can be controlled according to requirements, and thus the control over the proportions of different color rays in the light-emitting units at different positions is realized, thereby facilitating the improvement of a display effect.
