Abstract
The present application provides a pixel driving circuit, which comprises a driving transistor, a first switch, a second switch, a third switch, a fourth switch, a first capacitor, a second capacitor, an initial-voltage-signal terminal, a data-voltage-signal terminal, a reset-voltage-signal terminal, and a driving-voltage-signal terminal. 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 a 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. The present application further provides a pixel driving method and a display panel.
