Abstract
An LCD device and a driving method thereof are discussed. The LCD device can prevent a blended color within each block which is defined in an LCD panel. To this end, the LCD device divides an external image data into a plurality of block image data, generates first dimming signals opposite to red, green, and blue data with each block image data, and provides a second dimming signal opposite to a brightness data with each block image data. Also, the LCD device calculates a difference value between maximum and minimum grayscale values by analyzing histograms for the red, green, and compares the calculated difference value with a reference difference value. Furthermore, the LCD device allows one of the first and second dimming signals to be selected according to the dimming mode control signal.
