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 first switch is connected between the gate terminal and the drain terminal. The gate terminal is connected with the reset-voltage-signal terminal via the second switch. The source terminal is respectively connected with the driving-voltage-signal terminal and the data-voltage-signal terminal via the third switch and the fourth switch. The first capacitor is connected between the gate terminal and the charge-voltage terminal. The charge-voltage terminal is connected with a control terminal of the first switch. The second capacitor is connected between the gate terminal and the driving-voltage-signal terminal. The present application further provides a display panel.
