Abstract:
A pixel circuit, a method for driving a pixel circuit and a display panel are provided. An exemplary pixel circuit includes a data writing module and a driving transistor, a voltage of a first terminal of the driving transistor being greater than a voltage of a second terminal; a light-emitting control module and a light-emitting device, the light-emitting device being configured to emit light in response to the driving current generated by the driving transistor; a first initialization module and a second initialization module; and a reset module configured to cause the voltage of the second terminal of the driving transistor to be greater than or equal to the voltage of the first terminal of the driving transistor in response to a current-stage reset signal, an enable signal of the current-stage reset signal appearing after an enable signal of the current-stage light-emitting signal.
