Title:
DISPLAY SUBSTRATE AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/022084
Kind Code:
A1
Abstract:
A display substrate, comprising: a base, a plurality of first pixel units located on the base in a first display region, and a plurality of second pixel units located on the base in a second display region. A first light-emitting element comprised in each first pixel unit comprises a first anode, a first organic light-emitting structure, and a first cathode which are sequentially arranged in the direction away from the base. The first cathode is provided with a plurality of first openings, and the orthographic projections of the first openings on the base do not overlap the orthographic projection of a light-emitting region of the first light-emitting element on the base. A second light-emitting element comprised in each second pixel unit comprises a second anode, a second organic light-emitting structure, and a second cathode which are sequentially arranged in the direction away from the base. The sum of the areas of the light-emitting regions of the first light-emitting elements in the first display region is less than the sum of the areas of the light-emitting regions of the second light-emitting elements in the second display region.
