Abstract:
A pixel circuit, a method for driving a pixel circuit and a display device are provided. The pixel circuit includes a reset and precharge sub-circuit, a scanning compensation sub-circuit, a driving sub-circuit and a light-emission control sub-circuit, the scanning compensation sub-circuit comprises a storage capacitor, the light-emission control sub-circuit is configured to control a light-emitting device to emit light, the reset and precharge sub-circuit is coupled to the scanning compensation sub-circuit and the light-emission control sub-circuit, and is configured to reset the light-emission control sub-circuit according to a reset signal, and reset a second electrode of the storage capacitor of the scanning compensation sub-circuit according to a scanning signal; the scanning compensation sub-circuit is further coupled to the driving sub-circuit and the light-emission control sub-circuit, and is configured to charge the storage capacitor of the scanning compensation sub-circuit according to the scanning signal.
