摘要
Disclosed are various embodiments of methods, systems, devices and components for reducing power consumption in an LCD display that is backlit by LEDs. The various embodiments typically require the use of an array of backlighting LEDs disposed beneath and configured to emit light in the direction of an overlying LCD or LCD panel. In such an array, some LEDs are operated or driven at a first brightness, while other LEDs are operated or driven at a second brightness that is different from the first brightness, or at no brightness at all (i.e., such LEDs are turned off). LED brightnesses and therefore backlighting brightnesses over different portions of display or screen are varied and determined in accordance with the portion of display or screen that a user or processor has selected for viewing (“the area of interest”).
