  • High efficiency low power LED backlighting system for liquid crystal display
    Publication number: 20050231978
    Abstract: A backlighting system for liquid crystal display provides low power consumption and high efficiency. The backlighting system includes an array of LEDs arranged in a matrix to generate backlight needed to display light and dark colors on the liquid crystal display. The backlighting system emulates light and dark areas of video images being displayed on the liquid crystal display, selectively backlighting only areas of the liquid crystal display that require backlighting, thereby reducing power consumption.
