DISPLAY SUBSTRATE, DISPLAY APPARATUS, AND DRIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/279328
Kind Code:
A1
Abstract:
Embodiments of the present disclosure provide a display substrate and a display apparatus. The display substrate comprises: a base substrate; a plurality of pixels located on the base substrate, the pixels each comprising a light-emitting element and a pixel driving circuit, and the pixel driving circuits each comprising a light-emitting control circuit and a light-emitting driving circuit; and light-emitting control lines and first power lines, which are located on the base substrate, the light-emitting control lines and the first power lines being electrically connected to light-emitting control circuits, the light-emitting control lines being used to provide light-emitting control signals, and the first power lines being used to provide a first voltage. Light-emitting control circuits of a plurality of pixels located in two adjacent rows share the same light-emitting control line. The light-emitting control circuits each comprise a light-emitting control transistor; the light-emitting control transistors each comprise a gate, a first electrode, and a second electrode; the gate of each light-emitting control transistor is electrically connected to a light-emitting control line; one among the first electrode and the second electrode of each light-emitting control transistor is connected to a first power line; and the first power lines and the light-emitting control lines extend in parallel.
