Abstract: A pixel circuit includes a compensation module, a resetting module, a writing module, a driver module, a light emission enabling module, and a light emitting device. The resetting module is configured to reset the driver module and the light emitting device; the compensation module performs threshold voltage compensation on the driver module; the writing module is configured to write, to the driver module, a data voltage that is output by a data line; the light emission enabling module is configured to provide a voltage of a first supply voltage end to the driver module; the driver module is configured to provide, under action of the voltage output by the first supply voltage end, a drive current to the light emitting device; and the light emitting device is configured to emit light based on the drive current. The pixel circuit is configured to drive to display a subpixel.
