Abstract:
The present invention provides an AMOLED pixel driving circuit and a pixel driving method. The AMOLED pixel driving circuit comprises: a first, a second, a third, a fourth, a fifth, a sixth thin film transistors (M1, M2, M3, M4, M5, M6), a first, a second capacitors (C1, C2) and an organic light emitting diode (D1); wherein the third thin film transistor (M3) is a mirror thin film transistor, and the fourth thin film transistor (M4) is a drive thin film transistor, and the second thin film transistor (M2) is located between the third and the fourth thin film transistors (M3, M4). By controlling activation and deactivation of the second thin film transistor (M2) according to time sequence with the restore signal (Restore), the source voltage of the third thin film transistor (M3) is controlled to be pulled down to the earth voltage level (GND) in the restore stage to ensure that ensure that the gate-source voltages of the third, the fourth thin film transistors (M3, M4) are equal. Meanwhile, the data signal can be efficiently simplified to increase the charge time of the data signal.
