Abstract
A scanning drive system of AMOLED display panel is provided. The scanning drive system of AMOLED display panel of this disclosure comprises a gate drive circuit, a scanning signal selection circuit and a pixel drive circuit. The scanning signal outputted to the scanning signal selection circuit by gate drive circuit. The scanning signal selection circuit controls the first output terminal and the second output terminal simultaneously output the low-potential signal, scanning signal, or respectively output the low-potential signal and the scanning signal, or respectively output the scanning signal and the low-potential signal to the pixel drive circuit according to the first control signal and the second control signal. It could simultaneously achieve internal compensation and reduces requirement of output channel number of gate drive circuit, and enhances flexibility control a scanning signal selection circuit.
