Title:
PIXEL CIRCUIT AND DRIVING METHOD THEREOF, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/037536
Kind Code:
A1
Abstract:
The present invention relates to the technical field of displays, and particularly to a pixel circuit and a driving method thereof, and a display device. In the pixel circuit, a reset and pre-charge sub-circuit is connected to a scanning and compensation sub-circuit and a light-emission control sub-circuit for resetting the light-emission control sub-circuit according to a reset signal and pre-charging a storage capacitor in the scanning and compensation sub-circuit according to a scan signal; the scanning and compensation sub-circuit is further connected to a driving sub-circuit and the light-emission control sub-circuit for charging the storage capacitor in the scanning and compensation sub-circuit according to the scan signal and compensating the driving sub-circuit; the driving sub-circuit is further connected to the light-emission control sub-circuit for providing a driving current to a light-emitting device through the light-emission control sub-circuit; the light-emission control sub-circuit is further connected to the light-emitting device for controlling the light-emitting device to emit light according to a light-emission control signal.
