ABSTRACT:
An LCD apparatus includes a backlight array in which a plurality of light emitting devices illuminate an LCD panel with a plurality of colors; a backlight driver driving each light emitting device to emit light and adjust light intensity; a signal analyzer analyzing an input video signal and outputting transform objective information on the basis of an analyzed result; and a controller controlling the backlight driver to adjust a display state of a picture displayed on the LCD panel on the basis of the transform objective information from the signal analyzer. A picture is displayed on an LCD panel to have wide range colors of color coordinates and includes a backlight unit having a short response time. A display state of a picture displayed on the LCD panel is adjusted by analyzing an input video signal and controlling a backlight unit.
