Abstract:
A liquid crystal display device and method for driving the same is described for reducing a compensating deviation of a common voltage. The liquid crystal display device includes a liquid crystal display panel; a data driver for driving data lines of the liquid crystal display panel; a gate driver for driving gate lines of the liquid crystal display panel; and a common voltage compensating unit for generating a plurality of compensating signals for compensating respective distortions of common voltages at a plurality of common regions of a common electrode of the liquid crystal display panel by using common voltages fed back from the common regions, and supplying compensating signals corresponding to each of the plurality of common regions.
