Title:
DISPLAY SUBSTRATE AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/159422
Kind Code:
A1
Abstract:
Provided in the present disclosure are a display substrate and a display apparatus. The display substrate comprises a plurality of columns of first voltage lines and a plurality of rows and columns of pixel driving circuits, which are arranged on a base, wherein each pixel driving circuit comprises a drive transistor and a compensation transistor; an orthographic projection of a first voltage line on the base at least partially overlaps with an orthographic projection of a gate electrode of the drive transistor on the base; the gate electrode of the drive transistor is coupled to a first electrode of the compensation transistor by means of a first conductive connection portion; a second electrode of the compensation transistor is coupled to a first electrode of the drive transistor; and the orthographic projection of the first voltage line on the base at least partially overlaps with an orthographic projection of the first conductive connection portion on the base. The present disclosure can stabilize a gate voltage of a drive transistor and improve the transmittance of a display panel.
