Abstract
The present disclosure provides a pixel driver circuit, a pixel circuit, a display panel and a display device. The pixel driver circuit includes two pixel driving units having an identical structure. Each pixel driving unit includes a driving transistor and a driving control module. A gate electrode of the driving transistor is connected to the driving control module, a first electrode thereof receives a first power voltage, and a second electrode thereof is connected to the driving control module and a light-emitting element. The driving control module is connected to a data line, a gate line, and the gate electrode and the second electrode of the driving transistor, and controls a potential at the gate electrode of the driving transistor in accordance with a data voltage applied to the data line under control of a gate driving signal from the gate line, so as to turn on/off the driving transistor.
