    摘要： A backlight unit assembly, a liquid crystal display having the same, and a dimming method thereof are provided. The dimming method for a liquid crystal display includes setting a plurality of lookup tables, each lookup table having different data for adjusting luminance corresponding to a same grayscale, calculating a grayscale average of a whole liquid crystal display panel and grayscale averages of individual liquid crystal display panel blocks with respect to an image signal input to the liquid crystal display panel, selecting one of the plurality of lookup tables in accordance with the whole grayscale average, and calculating the data for obtaining the luminance corresponding to the individual grayscale averages in the selected lookup table, and adjusting and applying power to a light emitting diode assembly using the calculated data. In the case of displaying an image, which is dark on the whole and only a part of which is bright, power is applied with a wider pulse width at the same grayscale, and thus the image can be displayed with a desired luminance to minimize image distortion.

    摘要： In order to perform local dimming, a driving dimming duty cycle is generated using a target gamma curve (TGV), wherein the driving dimming duty cycle corresponds to a representative grayscale value (RGV) of each of a plurality of dimming unit areas. Each of a plurality of light unit blocks of a light source is driven based on the driving dimming duty cycle, wherein the light unit blocks correspond to the dimming unit areas, respectively. Therefore, a display apparatus may display an image having a higher contrast ratio than normal.
