Abstract:
1. A driving circuit of an active matrix organic light emitting diode (AMOLED) panel, comprising a driving transistor, a first transistor, a second capacitor, an organic light emitting diode, and a voltage adjustment module, wherein the driving transistor comprises a gate which is connected to one terminal of the second capacitor, a source which is connected to the other terminal of the second capacitor, and a drain which is connected to the voltage adjustment module; the first transistor comprises a gate which is connected to a row scan signal terminal, a source which is connected to the voltage adjustment module, and a drain which is connected to a data signal terminal; the second capacitor is connected between the gate of the driving transistor and the source of the driving transistor; the organic light emitting diode is connected between a low level signal terminal and the source of the driving transistor, or is connected between a high level signal terminal and the drain of the driving transistor; and the voltage adjustment module is connected to a first control signal terminal, a second control signal terminal and a high level signal terminal, and is further connected with the one terminal of the second capacitor, the gate of the driving transistor, and the source of the first transistor, for adjusting a gate-source voltage of the driving transistor such that a driving current of the driving transistor in a saturation status is independent of the threshold voltage of the driving transistor.
