Document Type and Number:
WIPO Patent Application WO/2023/137780
Kind Code:
A1
Abstract:
A display backplane and a display apparatus. The display backplane comprises a plurality of light-emitting sub-regions (1011), at least two light-emitting elements (12) being provided in each light-emitting sub-region (1011). A first light guide component (14) is arranged in each light-emitting sub-region (1011) and is located between the at least two light-emitting elements (12); the side of the first light guide component (14) close to each light-emitting element is provided with a second light reflection surface; and the orthographic projection, on the substrate (11), of the portion on the side of the first light guide component (14) away from the substrate falls in the coverage of the orthographic projection, on the substrate (11), of the portion on the side of the first light guide component (14) close to the substrate. The display backplane can increase the light-emitting intensity between the light-emitting elements (12) and thus relieve a problem of nonuniform display of a display backplane.
