ABSTRACT:
A circuit for stabilizing a common voltage of a liquid crystal display device includes a data driving unit for providing video data to a liquid crystal display panel and a gate driving unit for providing scan pulses to the liquid crystal display panel, a timing controller for outputting various control signals for controlling the data driving unit and the gate driving unit, and outputting the video data, and a common voltage output unit for controlling outputting of a common voltage provided to the liquid crystal display panel according to a gate output enable signal inputted from the timing controller to thereby minimize the common voltage from being unstable.
