Background plateau manipulation for display device power conservation
First Claim
1. A method for reducing power consumed by an electronics device that includes a liquid crystal display device, the method comprising:
- altering background video information to produce altered background video information such that the liquid crystal display device will consume less power when displaying the altered background video information than an amount of power that would be required to display the background video information without the alteration;
altering video information for a graphical user interface item such that the liquid crystal display device will consume less power when displaying the altered graphical user interface item than an amount of power that would be required to display the graphical user interface item without the alteration,wherein the video information for the graphical user interface item is altered at a first rate and the background video information is altered at a second rate that is greater than the first rate; and
displaying the altered background video information with the altered video information for the graphical user interface item.

Abstract
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.

14. A method for reducing power consumed by an electronics device that includes a display device, the method comprising:
-
a) altering video information for a graphical user interface item at a first rate to produce altered video information for the graphical user interface item such that the liquid crystal display device will consume less power when displaying the altered video information for the graphical user interface item than an amount of power that would be required to display the graphical user interface item without the alteration; b) altering background video information at a second rate, that is greater than the first rate, to produce altered background video information such that the display device will consume less power when displaying the altered background video information than an amount of power that would be required to display the background video information without the alteration; c) displaying the altered video information for the graphical user interface item and the altered background video information; and repeating a), b) and c), wherein for each iteration of a) and b), altering the background video information and altering the video information for the graphical user interface item maintains visibility of the graphical user interface item relative to the altered background video information when displayed. - View Dependent Claims (15, 16, 17, 18, 19)

20. A computer readable medium including instructions for reducing power consumed by an electronics device that includes a liquid crystal display device, the computer-readable medium comprising:
-
instructions for altering background video information to produce altered background video information such that the liquid crystal display device will consume less power when displaying the altered background video information than an amount of power that would be required to display the background video information without the alteration; instructions for altering video information for a graphical user interface item such that the liquid crystal display device will consume less power when displaying the altered graphical user interface item than an amount of power that would be required to display the graphical user interface item without the alteration, wherein video information for the graphical user interface item is altered at a first rate and the background video information is altered at a second rate that is greater than the first rate; and instructions for displaying the altered background video information with the altered video information for the graphical user interface item.
