LIQUID CRYSTAL DISPLAY AND DRIVING METHOD THEREOF

摘要

An LCD(Liquid Crystal Display) device and a driving method thereof are provided to prevent luminance difference between odd and even horizontal lines by compensating for charge amount difference between vertically adjacent pixel electrodes. An LCD(Liquid Crystal Display) device includes an LCD panel(102), and gate and data drivers(106,104). The gate driver drives gate lines of the LCD panel. The data driver responds at a first source output enable signal during a horizontal period when the polarity of pixel voltage signal in a previous horizontal period is inverted, responds at a second source output enable signal having a high logical period different from the first source output enable signal during a horizontal period having the same polarity of pixel voltage signal as the previous horizontal period, and supplies the pixel voltage signal to data lines of the LCD panel. At least one of the first and second source output enable signals is varied according to a frame frequency.
