Abstract
A pixel driving circuit, a pixel driving method and a light emitting display device are provided in the present invention. The pixel driving circuit includes first through fifth transistors and a capacitor and is for driving a light emitting diode. The third transistor forms a diode connection to make information of the threshold voltages of both the third transistor and the light emitting diode be stored in the capacitor in a data writing period. In a light emitting period, the second transistor compensates drift variation of the threshold voltages of the third transistor and the light emitting diode according to the information stored in the capacitor to provide a stable driving current for driving the light emitting diode.
