An active matrix organic light emitting diode (AMOLED) pixel driving circuit and driving method. The AMOLED pixel driving circuit comprises: a first thin film transistor (TFT) (T1), a second TFT (T2), a third TFT (T3), a fourth TFT (T4), a fifth TFT (T5), a capacitor (C1) and an organic light emitting diode<b/>(OLED) (D1). The first TFT (T1) and the second TFT (T2) are disposed symmetrically and have equal threshold voltages, and can be used for compensating for the threshold voltage of a driving TFT. The fifth TFT (T5) is disposed between a supply voltage (Vdd) and the first TFT (T1), namely, the driving TFT, and the fifth TFT (T5) is controlled to be turned on only at a driving stage (3) via a third scanning control signal (S3) according to a time sequence, thereby controlling the OLED (D1) to emit light only at the driving stage (3), thus avoiding unnecessary light emission of the OLED (D1), reducing power consumption, and improving display effect of a picture. |
