Abstract: A pixel circuit and a driving method thereof, and a display panel. The pixel circuit includes a driver circuit, a data writing circuit, a storage circuit, a light emitting element and a bias circuit. The driver circuit controls a drive current for driving the light emitting element to emit light. The data writing circuit writes a data signal to the control terminal of the driver circuit in response to a scan signal. The storage circuit stores the data signal written by the data writing circuit. The light emitting element emits light according to the drive current. The bias circuit applies a bias voltage to the second terminal of the light emitting element in response to a bias starting signal and according to a bias voltage amplitude signal, so as to reverse bias the light emitting element.
