Provided is an LCD device. The LCD device includes: an input unit, a backlight unit, a histogram analyzing unit, a data correcting unit, a liquid crystal panel driving unit, a duty ratio determining unit, and a lamp driving unit. The input unit inputs data corresponding to an image displayed on a liquid crystal panel, and the backlight unit includes a plurality of lamps. The histogram analyzing unit analyzes a histogram of data input from the input unit to generate a select signal according to a brightness state of the data. The data correcting unit corrects pixel data to be supplied to the liquid crystal panel using at least one of a plurality of gamma compensating characteristic curves. The liquid crystal panel driving unit drives the liquid crystal panel. The duty ratio determining unit generates a plurality of lamp-on signals. The lamp driving unit generates a lamp driving voltage corresponding to the lamp-on signal. |
