Abstract
The present disclosure provides a pixel driving circuit, a display panel and a driving method of the pixel driving circuit. The pixel driving circuit includes a first transistor, a second transistor, a third transistor, a fourth transistor, a sixth transistor, a driving transistor, a first capacitor and a fifth transistor. A gate electrode of the fifth transistor is coupled to a third input terminal, the third input terminal is coupled to a third control signal lead, and the third control signal lead maintains a low level in both the triggering sub-stage and the maintaining sub-stage of the capacitor resetting stage. The present disclosure can reduce the hysteresis of the driving transistor and improve the afterimage phenomenon of a display screen.
