Abstract: A pixel driving circuit, a pixel driving method and a display apparatus are provided. The pixel driving circuit includes a reset unit, a threshold compensation unit, a data writing unit, a drive transistor, a first storage capacitor and a light emitting device. According to the present disclosure, it is able to make the drive current generated by the drive transistor only related to the data voltage and the reference voltage but uncorrelated to the threshold voltage of the drive transistor when the drive transistor drives the light emitting device to display.
