An AMOLED pixel driving circuit and driving method. The AMOLED pixel driving circuit comprises: a first thin film transistor (T1), a second thin film transistor (T2), a third thin film transistor (T3), a capacitor (C1), and an organic light emitting diode (D1). A first scan signal (SCAN1) is input to the gate of the first thin film transistor (T1), a data signal (DATA) is input to the source thereof, and the drain is electrically connected to a first end of the capacitor (C1). A second scan signal (SCAN2) is input to the gate of the second thin film transistor (T2), the source thereof is electrically connected to a second end of the capacitor (C1), and the drain is electrically connected to the anode of the organic light emitting diode (D1). The gate of the third thin film transistor (T3) is electrically connected to the second end of the capacitor (C1), a first power signal (VDD) is input to the source thereof, and the drain is electrically connected to the anode of the organic light emitting diode (D1). A second power signal (VSS) is input to the cathode of the organic light emitting diode (D1). Therefore, the threshold voltage of a driver thin film transistor can be effectively compensated for, the luminance uniformity of the organic light emitting diode (D1) is ensured, and the display effect of a screen is improved.
