Abstract:
The present disclosure relates to display technologies and, in particular, to a pixel driving circuit, a pixel driving method, and a display device. The pixel driving circuit includes first to fifth switching elements, a driving transistor, a first storage capacitor, and a second storage capacitor. The pixel driving circuit can eliminate the influence on the driving current caused by the threshold voltage of the driving transistor, the voltage drop resulting from the wire resistance, and the aging of the electroluminescent element, so as to ensure the consistency of the driving current output by each pixel driving circuit and the uniformity of brightness of each pixel display.
