Title:
PIXEL CIRCUIT, PIXEL DRIVING METHOD, DISPLAY PANEL AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/062747
Kind Code:
A1
Abstract:
Provided are a pixel circuit, a pixel driving method, a display panel and a display apparatus. The pixel circuit comprises a light-emitting element, a drive circuit, a first energy storage circuit, a second energy storage circuit, a data write circuit and a compensation circuit, wherein the data write circuit is used for controlling, under the control of a gate drive signal provided by a gate line, the writing of a data voltage into a first end of the first energy storage circuit; the compensation circuit is controlled by a compensation control signal, and a control end of the drive circuit is in communication with a second end of the drive circuit; and the drive circuit is used for generating, under the control of the electric potential of the control end thereof, a drive current which is used for driving the light-emitting element. By means of the present disclosure, a threshold voltage compensation time can be adjusted, and mura (uneven brightness) problems caused by a short threshold voltage compensation time under a high frequency condition are reduced.
