Abstract
A driving apparatus and method of an LCD device improves the brightness and the contrast ratio of an image. The driving apparatus includes an LCD panel for displaying an image corresponding to a data signal. A data driver supplies the data signal to the LCD panel. A gate driver supplies a scan signal to the LCD panel. A picture quality improving unit generates a histogram by dividing brightness components of input data into levels, generates data with an extended contrast ratio, and then generates a brightness control signal according to the average value of the histogram. A timing controller supplies reordered data, and controls the data driver and the gate driver. A backlight provides light to the LCD panel. An inverter drives the backlight based on the brightness control signal.
