ABSTRACT:
Described herein are power conservation systems and methods that reduce power consumption for an electronics device including a liquid crystal display (LCD). The LCD includes a backlight that offers multiple luminance levels, where each level consumes a different amount of power. The systems and methods alter video information while the backlight remains at a backlight luminance level. The alteration reduces luminance for the video information to produce new video information that can be presented at a lower backlight luminance level. Change to the lower backlight luminance level may then occur without significantly affecting aggregate luminance of the new video information, as perceived by a user. The LCD and electronics device consume less power at the lower luminance level.
