A pixel driving circuit includes: current control sub-circuit outputting driving current in response to light emission control signal of the light emission control signal terminal; time control sub-circuit transmitting time modulation signal of the time modulation signal terminal to the third control terminal in response to time control signal of the time control signal terminal, and controlling time during which the driving current flows through the light emitting element; initial time control sub-circuit transmitting initial control signal of the initial control signal terminal to the output terminal of the initial time control sub-circuit in response to initial time control signal of the initial time control signal terminal. Time control sub-circuit controls the time during which the driving current flows through the light emitting element in response to time modulation signal transmitted to the third control terminal and initial control signal transmitted to the third control terminal.
