Abstract:
Disclosed is a local dimming liquid crystal display device. The present local dimming liquid crystal display device comprises a display panel unit having a plurality of pixels; a panel driving unit for driving each of the plurality of pixels; a backlight unit comprising a plurality of backlights for dividing the display panel unit into a plurality of areas to emit light to each of the plurality of regions; a backlight driving unit for driving the plurality of backlights on the basis of gray level information of the plurality of pixels corresponding to each of the plurality of areas; and a processor for calculating a first amount of light to be incident on each pixel on the basis of the gray level of each pixel, calculating a second amount of light incident on each pixel in accordance with a driving state of the plurality of back-lights, changing the gray level of at least one of the plurality of pixels on the basis of the difference between the first amount of light and the second amount of light, and controlling the panel driving unit on the basis of the changed gray level.

Claim (Index 6):
The LCD device of  claim 5 , wherein the processor is configured to calculate the amount of gray level adjustment through the following equation:\n \u0394=( B ( x,y ))\u00d7( I ( x,y )\u2212\u03b4( I ( x,y ))) where B(x,y) is the second amount of light at the pixel located at coordinates (x,y), \u03bb(B(x,y)) is a predetermined function regarding B(x,y), and \u03b4(I(x,y)) is a predetermined function regarding I(x,y).
