Abstract: 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.

Abstract: A driving apparatus and method are presented to drive lamps that irradiate a liquid crystal display panel of a liquid crystal display device. A picture implementing period, during which a picture is implemented by the liquid crystal display device, and a shorter, scanning period before the picture implementing period are established. An output power supplied to the lamps to set a reference brightness is determined. A lamp driver changes a duty ratio and/or an amplitude of an AC signal supplied to the lamps to establish the reference brightness during the scanning period. The duty ratio/amplitude of the AC signal is adjusted dependent on the characteristics of the liquid crystal material in the liquid crystal display.
