1. A method for reducing power consumed by a liquid crystal display device, the method comprising:
- displaying an active graphics component in a first portion of a display area provided by the liquid crystal display device;
immediately upon determination of user inactivity in an inactive portion of the display area that is outside the first portion which has not been determined to include user inactivity, altering video information in the inactive portion; and
reducing backlit luminance of the liquid crystal display device and increasing transmittance of the liquid crystal display panel.

Abstract
Described herein are systems and methods that that reduce power consumption for an electronics device that includes a display. The power conservation systems and methods alter background video information not needed for interactive use when a user returns to a display after some period of inactivity. Power conservation also preserves video information for one or more graphical user interface items. Preserving a graphics item maintains a person'"'"'s ability to detect the graphical user interface item, and return to it at a later time, even though the background video information has been altered to conserver power.
