Title:
PIXEL CIRCUIT AND DRIVING METHOD THEREFOR, AND DISPLAY PANEL AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/201678
Kind Code:
A1
Abstract:
A pixel circuit and a driving method therefor, and a display panel and a display apparatus. The pixel circuit comprises: a data write circuit, a driving circuit, and a compensation circuit, wherein the driving circuit comprises a control end, a first end, and a second end; the compensation circuit is connected to the control end, the first end and the second end of the driving circuit, and is configured to write a compensation voltage based on a first reset voltage into the control end of the driving circuit under the control of a compensation control signal; the data write circuit is connected to the control end of the driving circuit, and is configured to write a coupling voltage based on a data voltage into the control end of the driving circuit under the control of a scanning signal; and the driving circuit is configured to control, under the control of a voltage applied to the control end of the driving circuit, a driving current for driving a light-emitting element to emit light.
