摘要：
A negative voltage signal generation circuit is described. The first thin film transistor (TFT) connects the first ground terminal to the control signal generation unit. The second TFT switch connects to the first TFT switch, the control signal generation unit and the negative voltage signal output terminal. The first capacitor connects to the first TFT switch, the second TFT switch and the control signal generation unit. The present invention is capable of improving the stability of the negative voltage signal generation circuit.
