A method for driving a pixel circuit is disclosed. The method includes: a time for displaying a frame including N initialization phases and N data signal voltage writing phases before a light-emitting phase. The ith of the N data signal voltage writing phases is after the ith of the N initialization phases and before the (i+1)th of the N initialization phases, and the Nth data signal voltage writing phase is after the Nth initialization phase, 1≤i≤N−1, i is an integer and N is an integer greater than 1. In the initialization phase, an initialization voltage is applied to the gate electrode of the driving transistor by the initialization module. In the data signal voltage writing phase, a data signal voltage is applied to the gate electrode of the driving transistor by the data signal voltage writing module.
