摘要： A liquid crystal panel includes a plurality of display regions that correspond to the division images. The number of the division images can be set with consideration of the number of lamps covering the display regions. The average brightness of an entire image is compared with the average brightness of the division images so as to vary brightness of each division image according to a comparison result. Light that corresponds to the varied brightness is illuminated to each display region. Therefore, a dark division image is displayed darker and a bright division image is displayed brighter in the image of one frame, thereby enhancing a contrast ratio and reducing power consumption.
