摘要： A luminance control apparatus of a liquid crystal display device (LCD) is presented. The LCD includes a liquid crystal display panel divided into areas, lamps, an arithmetic unit, and a lamp driver. Fewer lamps are present than the number of areas. The arithmetic unit scans pixels of each area, extracts a peak value of the gray level of pixels of the area, and calculates a maximum peak brightness value and an average value of the area. The lamp driver controls the brightness of the lamps in accordance with the average value and the maximum peak brightness value.
