Abstract
A pixel driver circuit, a display device, and a pixel driving method are provided. The pixel driver circuit includes a driving module for providing a drive current to a pixel; a threshold voltage compensation module for providing threshold voltage compensation for the driving module; and a first switch module, a second switch module, a third switch module, and a fourth switch module, the terminals of each of which are electrically connected to various components in a particular manner. According to the embodiments of the present application, the threshold voltage of the driving transistor can be effectively compensated.
