Abstract
The present application provides a pixel driving circuit, which comprises a driving transistor, which comprises a gate terminal, a source terminal, and a drain terminal. The source terminal is respectively connected with a driving-voltage-signal terminal and a charge-voltage terminal via a first switch and a second switch. The charge-voltage terminal is connected with a data-voltage-signal terminal via a third switch. The gate terminal is connected with an initial-voltage-signal terminal via a fourth switch, and the gate terminal is connected with the drain terminal via a fifth switch. A first capacitor is connected with the gate terminal and the charge-voltage terminal, a second capacitor is connected with the gate terminal and a ground terminal. The present application further provides a pixel driving method and a display panel.
