Patent ID: 8754836

Claim:
A driving circuit for driving a liquid crystal display device having a plurality of gate lines, data lines and switch elements connected to the gate and data lines, comprising: a data driver for applying a plurality of data signals to the data lines; a gate driver for applying a plurality of gate signals to the gate lines; a timing controller for providing a plurality of timing controlling signals to the data and gate drivers; a power supply for generating a power voltage; and a discharging circuit for applying a first signal and a second signal to the gate driver in accordance with the power voltage, wherein the discharging circuit comprises: a first partial circuit for receiving a control signal for reducing a rear portion of a gate pulse of the plurality of gate signals and a maintenance signal for determining a predetermined time period for the first signal and comparing the power voltage to a reference voltage; and a second partial circuit for receiving one of the maintenance signal and the control signal as a varied flicker signal from the first partial circuit and for generating the second signal according to the varied flicker signal, wherein the first partial circuit outputs the control signal as the varied flicker signal to the second partial circuit in response to the timing controller when the power voltage is higher than the reference voltage, wherein the first partial circuit outputs the first signal to the gate driver and outputs the maintenance signal as the varied flicker signal to the second partial circuit in response to the timing controller when the power voltage is lower than the reference voltage.
