Abstract
Provided is a pixel driving circuit. The pixel driving circuit includes a reset unit, a storage unit, an initialization unit, a drive unit, a threshold compensation unit, and a data write unit. A first terminal of the reset unit is configured to input the signal output by a reset power supply. A second terminal of the reset unit is connected to the control terminal of the drive unit and configured to provide the reset power supply for the control terminal of the drive unit during a power-on period. During the power-on period of the pixel driving circuit, the reset unit provides the reset power supply for the drive unit and performs reset control on the drive unit, so that the drive unit is prevented from being abnormally turned on during a power-on stage, thereby avoiding a screen flicker phenomenon.
