Document Type and Number:
WIPO Patent Application WO/2023/231677
Kind Code:
A1
Abstract:
A pixel circuit and a driving method therefor, and a display device. The pixel circuit comprises a voltage control module (10), a current control module (20) and a light-emitting module (30); the voltage control module (10) comprises a first driving module (101), a coupling module (102) and a first voltage writing module (103), and the coupling module (102) is configured to couple a reset signal (Set) to a control end (G1) of the first driving module (101) so as to reset the voltage of a control end of the current control module (20); or the voltage control module (10) further comprises a reset module (104), the reset module (104) is connected between a first power line (L1) and the control end of the current control module (20), and the reset module (104) is configured to reset the voltage of the control end of the current control module (20).
