Abstract:
The present disclosure provides a pixel driving circuit, a display panel, and a display device. The pixel driving circuit includes a first reset transistor connected between a first reset voltage end and a gate electrode of a driving transistor, a first capacitor connected in series between the gate electrode of the driving transistor and one of a source electrode or a drain electrode of the driving transistor, and a second capacitor connected in series between the first capacitor and a second voltage end, thereby reducing an influence of a threshold voltage of the driving transistor on a driving current and ensuring light emission stability of light-emitting devices.
