Title:
DISPLAY SUBSTRATE AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/225966
Kind Code:
A1
Abstract:
A display substrate, comprising a base, a scanning signal line, a plurality of first pixel circuits and a plurality of first light-emitting devices. The plurality of first pixel circuits are arranged on the base, and are located in a functional device arrangement region. At least one first pixel circuit comprises a first transistor and a driving transistor, wherein a control electrode of the first transistor is electrically connected to the scanning signal line; a first electrode of the first transistor is electrically connected to a second electrode of the driving transistor; and a second electrode of the first transistor is electrically connected to a control electrode of the driving transistor. The plurality of first light-emitting devices are arranged on the sides of the plurality of first pixel circuits that are away from the base. The first light-emitting device comprises a first electrode. The plurality of first light-emitting devices comprise a first-color light-emitting device, and the plurality of first pixel circuits comprise a first-color pixel circuit, which is electrically connected to the first-color light-emitting device. The orthographic projection of a channel region of the first transistor of the first-color pixel circuit on the base at least partially overlaps the orthographic projection of the first electrode of the first-color light-emitting device on the base.
