Title:
PIXEL CIRCUIT AND DRIVING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/184916
Kind Code:
A1
Abstract:
A pixel circuit, comprising a data writing and compensation sub-circuit, a driving sub-circuit, a light emission control sub-circuit, and a light-emitting sub-circuit. The data writing and compensation sub-circuit is connected to the driving sub-circuit, a first control signal terminal, and a data voltage terminal, and is configured to input a data signal output by the data voltage terminal to the driving sub-circuit, and compensate for the threshold voltage of the driving sub-circuit; the light emission control sub-circuit is connected to the driving sub-circuit, the data writing and compensation sub-circuit, a second control signal terminal, a first voltage terminal, and a second voltage terminal, and is configured to input a first voltage signal output by the first voltage terminal to the driving sub-circuit and the data writing and compensation sub-circuit, and input a second voltage signal output by the second voltage terminal to the driving sub-circuit; the driving sub-circuit is further connected to the light-emitting sub-circuit, and is configured to input a signal output by the light-emitting control sub-circuit to the light-emitting sub-circuit; and the light-emitting sub-circuit is further electrically connected to a third voltage terminal, and is configured to emit light.
