Abstract: The present invention provides a pixel driving circuit, a pixel driving method, and a display device. The pixel driving circuit comprises a driving transistor, a light-emitting device and a threshold compensation unit; a control electrode, a first electrode and a second electrode of the driving transistor are all connected with the threshold compensation unit; the threshold compensation unit is connected with a data line, a first power supply terminal, and a first terminal of the light-emitting device. In the technical solution of the present invention, by providing the sum of the data voltage and the threshold voltage of the driving transistor to the control electrode of the driving transistor, a driving current generated by the driving transistor is independent of the threshold voltage of the driving transistor, so as to prevent the driving current from being influenced by non-uniformity and shift of the threshold voltage.
