An AMOLED pixel driving circuit and pixel driving method. The AMOLED pixel driving circuit uses a 3T1C structure, and comprises a first thin film transistor (T1), a second thin film transistor (T2), a third thin film transistor (T3), a memory capacitor (Cs), and an organic light-emitting diode (OLED). A second scan signal voltage (Vsel2) is introduced, and an initial low potential (Vini) of data signal voltage (VData) is provided to the first thin film transistor (T1), i.e. the source electrode of the driving thin film transistor (T1), by means of the third thin film transistor (T3) in the reset stage (S1), so that variations of the threshold voltage (Vth) of the driving thin film transistor (T1) can be effectively compensated, and the complexity of a supply voltage signal can be reduced. |
