Abstract
A pixel circuit and a driving method thereof and a display device are provided. In the pixel circuit, a driving circuit is configured to control a driving current flowing through a first terminal and a second terminal of the driving circuit for driving a light emitter element to emit light; a data writing circuit is configured to write a data signal to a control terminal of the driving circuit in response to a scan signal; a first light emission control circuit is configured to apply a first voltage to the first terminal in response to a first light emission control signal; a first reset circuit is configured to apply a reset voltage to the control terminal in response to a first reset signal. The driving circuit is in a fixed bias state when the reset voltage and the first voltage are applied together to the driving circuit.
