Abstract

A pixel driving circuit includes 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, and a driving-voltage-signal terminal. The driving transistor includes a gate terminal, a source terminal, and a drain terminal. The first switch is disposed between the gate terminal and the drain terminal. The gate terminal is connected with the initial-voltage-signal terminal via the second switch. The source terminal is connected with the driving-voltage-signal terminal and the data-voltage-signal terminal via the third switch and the fourth switch, respectively. The first capacitor is connected between the gate terminal and a ground terminal. The second capacitor is connected between the gate terminal and the source terminal. A pixel driving method and a display panel are also provided.
