Abstract: There is provided a driving method of a liquid crystal display device that is driven by an inversion method, including: calculating a total sum of changed amounts of data voltages between an (n−1)-th row line and an n-th row line, using image data of the (n−1)-th row line and image data of the n-th row line; generating common voltage data according to the total sum of the changed amounts of the data voltages; compensating for the common voltage data using a characteristic parameter of a liquid crystal panel; and generating a common voltage according to the compensated common voltage data, and outputting the common voltage to the liquid crystal panel.
