Title:
PIXEL CIRCUIT, DRIVING METHOD, DISPLAY SUBSTRATE, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/023930
Kind Code:
A1
Abstract:
Provided in the present disclosure are a pixel circuit, a driving method, a display substrate, and a display apparatus. The pixel circuit comprises a driving circuit, an energy storage circuit, a first control circuit, a first reset circuit and a data writing circuit. The first control circuit controls, under the control of a light emission control signal, a second node to communicate with a first end of the driving circuit; under the control of a first reset control signal, the first reset circuit writes a reference voltage into the second node; under the control of a scanning signal, the data writing circuit writes a data voltage into the first end of the driving circuit; and the driving circuit is used to enable, under the control of a control end of the driving circuit, the first end of the driving circuit to be connected to a second end of the driving circuit. The present disclosure solves the problem of an existing pixel circuit being incapable of fully realizing power source voltage compensation.
