Abstract:
The invention provides an AMOLED pixel driving circuit, driving method and terminal. The AMOLED pixel driving circuit adopts a 6T1C structure, comprising a first TFT, i.e., driving TFT, a second TFT, a third TFT, a fourth TFT, a fifth TFT, a sixth TFT, a storage capacitor and an OLED; the scan signal, the first light-emitting control signal and the second light-emitting control signal are combined to successively correspond to a reset phase, a compensation phase and a light-emitting phase, so that the driving current flowing through the OLED is independent of the threshold voltage of the driving TFT and the positive power voltage. The invention compensates for the threshold voltage drift of the driving TFT and also for the voltage drop in positive power voltage.
