Abstract
A pixel driving circuit includes: a driving transistor connected to a first node, a second node and a third node; a first light-emitting control unit connected to the second node; a second light-emitting control unit connected to the third node and a fourth node; a first reset unit connected to the fourth node, and configured to load a second power supply voltage to the fourth node in response to a scan signal. One end of the light-emitting element is connected to the fourth node, and the other end of the light-emitting element is used for loading the second power supply voltage.
