Abstract:
The embodiment of the invention provides a pixel driving circuit, a driving method for the pixel driving circuit and a display device, and relates to the technical field of display. According to the pixel driving circuit, the driving method for the pixel driving circuit and the display device, the situation that driving currents of an active light emitting device are affected by threshold voltage shift of a driving transistor can be avoided, and therefore the evenness of a displayed image is improved. The pixel driving circuit comprises a light emitting device, a storage capacitor, a driving unit and five switching units. The embodiments of the invention are used in e.g. display devices and manufacturing the same.
