Described herein are systems and methods 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 conserve power.
