Abstract
A pixel driving circuit, a display panel and a display device. The pixel driving circuit includes a drive transistor, a storage module, a data writing module, a first initialization module, a second initialization module and a light-emitting element. The first initialization module is configured to initialize the gate of the drive transistor. The control terminal and the first terminal of the second initialization module are connected to a scan signal input terminal. The second initialization module is configured to initialize the light-emitting element. The data writing module is configured to write a data voltage into the gate of the drive transistor. The storage module is configured to store a gate voltage of the drive transistor. The drive transistor is configured to output a drive current according to the data voltage to drive the light-emitting element to emit light.
