Title:
PIXEL CIRCUIT, PIXEL DRIVING METHOD, DISPLAY SUBSTRATE, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/046066
Kind Code:
A1
Abstract:
A pixel circuit, a pixel driving method, a display substrate, and a display apparatus. The pixel circuit comprises a driving circuit (11), a first reset circuit (12), a first node control circuit (13), a first light-emitting control circuit (14), and a light-emitting element (E0). The first reset circuit (12), under the control of the potential of a first node (N1), writes a first initial voltage (Vi1) into a first electrode of the light-emitting element (E0). The first node control circuit (13) controls the potential of the first node (N1) according to the data voltage (Vdata) and the threshold voltage of a drive transistor (T0) comprised in the driving circuit (11). The first light-emitting control circuit (14), under the control of a light-emitting control signal, controls a second end of the driving circuit (11) to be in communication with the first electrode of the light-emitting element (E0). The driving circuit (11) is used for generating a driving current.
