1. A pixel driving circuit, comprising a driving transistor, a first switch, a second switch, a third switch, a fourth switch, a first capacitor, a second capacitor, a charge-voltage terminal, an initial-voltage-signal terminal, a data-voltage-signal terminal, a reset-voltage-signal terminal, and a driving-voltage-signal terminal;

  • wherein the driving transistor comprises a gate terminal, a source terminal, and a drain terminal;

    the first capacitor is connected between the source terminal and the gate terminal, the second capacitor is connected between the source terminal and the charge-voltage terminal;

    the charge-voltage terminal is respectively connected with the reset-voltage-signal terminal and the data-voltage-signal terminal via the first switch and the second switch;

    the drain terminal is connected with the driving-voltage-signal terminal via the third switch;

    the gate terminal is connected with the initial-voltage-signal terminal via the fourth switch.
