Abstract
A liquid crystal display (LCD) device and a method for driving the same, which are capable of achieving an enhancement in display quality, are disclosed. The LCD device includes a display panel for displaying an image, a backlight unit comprising a plurality red light sources, a plurality of green light sources, and a plurality of blue light sources, a backlight driver for controlling a duty rate of a first drive signal to drive the red light sources, a duty rate of a second drive signal to drive the green light sources, and a duty rate of a third drive signal to drive the blue light sources, in accordance with a control signal including color coordinate information and luminance information, a luminance corrector for varying the luminance information of the control signal when the duty rate of one of the first to third drive signal is 100%, and a light sensor for sensing light beams from the light sources, generating light sensing signals based on the sensed light beams, and supplying the light sensing signals to the backlight driver and to the luminance corrector.
