Abstract
Provided are a pixel circuit and a drive method therefor, a display panel and a display device. The pixel circuit includes: a light emitting device; a drive transistor configured to generate, according to a data voltage, a drive current for driving the light emitting device to emit light; a data writing circuit coupled to the drive transistor, where the data writing circuit is configured to input the data voltage in response to a signal applied to the data writing circuit; and a voltage control circuit coupled to the drive transistor, where the voltage control circuit is configured to reset a control electrode, a first electrode and a second electrode of the drive transistor in response to a signal applied to the voltage control circuit before the data voltage is input.
