Abstract
A pixel circuit, a method for driving the same, a display panel and a display device are provided. The pixel circuit includes: a resetting sub-circuit, a data writing sub-circuit, a driving sub-circuit, a first light-emission controlling sub-circuit, a second light-emission controlling sub-circuit, an anode potential controlling sub-circuit, a capacitor sub-circuit, and a light-emitting element, all of which operate in cooperation so that the pixel circuit drives the light-emitting element to emit light, where the second light-emission controlling sub-circuit provides voltage at an output terminal of the driving sub-circuit to an anode of the light-emitting element in a light-emission period, and the anode potential controlling sub-circuit provides a signal of a first voltage signal terminal to the anode of the light-emitting element in a non-light-emission period.
