A signal processing circuit to provide a gate voltage to the liquid crystal display

The present invention relates to a circuit of the gate voltage signal provided to the LCD display processing types, comprising: input-output unit and a control unit, wherein the input unit receives the output signal of the gate voltage, the control unit receives the control signal and the control signal in accordance with the input-output unit outputs a first output signal during a first time period in each cycle of the signal based on the gate voltage, it outputs a second output signal during the second period, the third output signal during a third period, the fourth time fourth output signal during the output period. In the circuit gate voltage signal supplied to the liquid crystal display according to an exemplary embodiment of the process of the present invention, it can be changed to different values ​​of gate voltage signal to reduce the gate voltage signal during different time periods of each cycle lowering speed of the voltage, thereby reducing the impact on the reference voltage of the liquid crystal display.
