The present invention provides an AMOLED pixel drive circuit, drive method and drive array system, said driving circuit comprising: a first transistor, a second transistor, the organic light emitting diode and the driving transistor, the driving transistor threshold voltage is adjustable; the first a transistor connected to the gate of the first scan signal, a first gate electrode connected to a voltage signal, a second control gate electrode connected to the driving transistor; the source of the driving transistor is grounded, a drain connected to the first organic light emitting diode a pole; the organic light emitting diode a second external power source is connected; a gate connected to a second scan signal of the second transistor, a first electrode connected to the data signal, a second electrode connected to a first electrode of the organic light emitting diode . The present invention uses an adjustable threshold value instead of the traditional drive transistor and a PMOS transistor capacitance, greatly increased the relative aperture of the pixel structure, which greatly improved the efficiency of the light emitting pixel structure.
