Abstract: The present application provides a pixel driving circuit and a display panel. The pixel driving circuit includes an amplitude regulating module and a pulse width modulation module, where the amplitude regulating module and the pulse width modulation module are both electrically connected to a first node, so that the pulse width modulation module and the amplitude modulation module are configured to cooperate with a first data signal and a second data signal, respectively, to realize regulation of both the pulse width and the amplitude of the valid pulse of the driving current signal for driving the light emitting device to emit light. As such, the valid pulse of the driving current signal has different pulse widths and different amplitudes under correspondingly different gray scale states, so that the light emitting brightness and the light emitting duration of the light emitting device under correspondingly different gray scale states are different.
