The present application discloses a method for driving a pixel circuit. The method includes initializing a voltage setting in a pixel circuit including at least a driving transistor coupled to a light-emitting device and obtaining a first threshold voltage of the driving transistor. The method further includes inputting a first data voltage to the pixel circuit to generate a first driving current independent of the first threshold voltage, to drive light emission of the light-emitting device in a current cycle. Additionally, the method includes generating a compensation voltage via a feedback sub-circuit based on a change of the first driving current upon a second threshold voltage of the light-emitting device. Furthermore, the method includes inputting a second data voltage combined with the compensation voltage as a negative feedback to generate a second driving current to drive light emission of the light-emitting device in a next cycle.
