A pixel driving circuit, an array substrate, a display device, and a pixel driving method. The pixel diving circuit comprises a driving unit, a switch unit, a threshold voltage compensation module and a light-emitting device. The threshold voltage compensation module is respectively connected to a scanning signal line, a first control line, a second control line, a second power source and the switch unit. The light-emitting device is respectively connected to the second power source and the threshold voltage compensation module. The driving unit is respectively connected to a first power source and the threshold voltage compensation module. The switch unit is respectively connected to the scanning signal line and a data signal line. The threshold voltage compensation module comprises a threshold voltage holding unit, an anti-interference unit, an auxiliary gating unit and a charge and discharge control switch unit. An operating current of the light-emitting device is independent of a threshold voltage of the driving unit, so that the light-emitting brightness of the light-emitting device is uniform, thereby improving the uniformity of the light-emitting brightness of a display device. |
