Abstract:
1. A method of minimizing power consumption in a display comprising a liquid crystal display (“LCD”) and a plurality of LEDs disposed beneath the LCD and configured to provide backlighting thereto, comprising: (a) selecting or determining an area of interest on the display; (b) modulating power delivered to a first group of LEDs located within or overlapping the area of interest such that light emitted by the first group of LEDs has a first brightness associated therewith, and (c) modulating power delivered to a second group of LEDs located outside or substantially not overlapping the area of interest such that light emitted by the second group of LEDs has a second brightness associated therewith, the first brightness being greater than the second brightness, wherein a position on the display is selected to determine the area of interest and wherein a boundary of the area of interest is defined at least partially by a first predetermined distance from the position on the display.
