Abstract
Electronic device and a method for backlighting a liquid crystal display (LCD) display to provide different display definitions, the LCD display includes a backlight unit composed of one or more backlighting blocks. The method determines a display definition of a video image and illuminates or turns off backlighting blocks of the backlight unit to display the video image accordingly. The video image is displayed in full screen by all backlighting blocks if the video image is an ultra high definition (UHD) image, and turns on a smaller number of the backlighting blocks to display the video image if the video image has other than UHD display definition. As such, the electronic device is controlled to save power consumption in different display definitions of the LCD display.
