摘要:
The present disclosure provides a pixel driving circuit, a pixel driving method and a display apparatus. The pixel driving circuit includes a pre-charging control unit, a storage capacitor, a driving transistor and a threshold compensation unit. The pre-charging control unit charges the storage capacitor by a supply voltage during a pre-charging period; the threshold compensation unit during the threshold compensation period, together with the driving transistor and under the control of the control signal, controls the storage capacitor to be discharged until a voltage of the second electrode of the driving transistor becomes Vdata+Vth; and during a light-emitting period, control a gate-source voltage of the driving transistor to compensate for Vth, where Vth is a threshold voltage of the driving transistor, and Vdata is a voltage of the data signal.
