Title:
PIXEL CIRCUIT AND DRIVING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/230790
Kind Code:
A1
Abstract:
The present disclosure provides a pixel circuit and a driving method therefor, and a display device. In the pixel circuit, a first reset transistor is coupled between a gate of a driving transistor and an initialization signal end, and has a gate coupled to a reset control end; a compensation transistor is coupled between the gate and a first electrode of the driving transistor, and has a gate coupled to a first scanning control end; a data writing transistor is coupled between a second electrode of the driving transistor and a data signal end, and has a gate coupled to a second scanning control end; a first light-emitting control transistor is coupled between the second electrode of the driving transistor and a first power supply end, and has a gate coupled to a light-emitting control end; a second light-emitting control transistor is coupled between the first electrode of the driving transistor and a first electrode of a light-emitting device, and has a gate coupled to the light-emitting control end; a second reset transistor is coupled between the first electrode of the light-emitting device and the initialization signal end, and has a gate coupled to the second scanning control end; and a second electrode of the light-emitting device is coupled to a second power supply end.
