发明名称 CIRCUIT FOR REMOVING RESIDUE VOLATAGE OF LIQUID CRYSTAL DISPLAY
摘要 An apparatus for removing residual voltages of an LCD device is provided to discharge residual voltages charged in pixels by increasing rapidly gate-off voltages when power is turned off. An apparatus for removing residual voltages of an LCD(Liquid Crystal Display) device includes a drain voltage outputting unit(41), a pull-up controller(42), and a gate-off voltage pull-up unit(43). The drain voltage outputting unit drops a drain voltage up to a level. The pull-up controller detects the drop of the drain voltage and outputs a pull-up control voltage on a gate-off voltage in the drop. The gate-off voltage pull-up unit, which is turned on by the pull-up control voltage, pulls up the gate-off voltage by a voltage outputted from the drain voltage outputting unit.
