Abstract: An LCD device is provided to replace the black gradation area of an existing gamma voltage generator with a common voltage generator to have no need to generate a separate common voltage generator, thereby reducing the entire size of a PCB(Printed Circuit Board) and cost. An LCD(Liquid Crystal Display) panel(30) displays an image. A gamma/common voltage generator(22) generates a gamma voltage and a common voltage to supply the gamma voltage and the common voltage to the LCD panel respectively. A tuning unit(27) produces common voltage values changed according to different sizes of LCD panels as optimal common voltage values. A storage unit(25) stores the optimal common voltage values provided from the tuning unit in an LUT(Look Up Table) form.

Abstract: An LCD(Liquid Crystal Display) is provided to achieve a high-speed response speed of a liquid crystal by changing a level of a common voltage when gradations between frames drastically change, and thus increasing a potential difference between a gradation data voltage and a common voltage of a corresponding frame. An LCD panel(400) includes a liquid crystal capacitor, and displays an image by using a potential difference between a data voltage applied to one end of the liquid crystal capacitor and a common voltage applied to the other end. A driving unit outputs a compensation data to one end of the liquid crystal capacitor in order to increase a response speed of a liquid crystal when data is input from the outside, and changes a level of a common voltage when gradations between frames drastically change and outputs the common voltage to the other end of the liquid crystal capacitor.
