Claims18
A method for reducing power consumed by a liquid crystal display television, the method comprising:
- displaying an active graphics component in a first portion of a display area provided by the liquid crystal display television;
- in response to video inactivity in an inactive portion of the display area that is outside the first portion, reducing luminance for a backlight portion for the liquid crystal display television such that the liquid crystal display television will consume less power when displaying the altered video information than an amount of power that would be required to display the video information in the inactive portion without the alteration;
- and
- simultaneously displaying the active graphics component in the first portion and the altered video information in the inactive portion on the liquid crystal display television.
A method for reducing power consumed by a backlit liquid crystal display television, the method comprising:
- displaying a graphics component in a first portion of a display area provided by the backlit liquid crystal display television;
- in response to user inactivity in an inactive portion of the display area that is outside the first portion, altering video information in the inactive portion such that that luminance for video information in the inactive portion decreases;
- reducing backlight luminance in the inactive portion for the liquid crystal display television such the backlit liquid crystal display television will consume less power when displaying the altered video information;
- and
- simultaneously displaying the graphics component in the first portion and the altered video information in the inactive portion.
A computer readable medium including executable instructions for reducing power consumed by a liquid crystal display television, the executable instructions comprising:
- instructions for displaying an active graphics component in a first portion of a display area provided by the liquid crystal display television;
- in response to video inactivity in an inactive portion of the display area that is outside the first portion, instructions for altering a backlight portion for the liquid crystal display television will consume less power when displaying the altered video information than an amount of power that would be required to display the video information in the inactive portion without the alteration
- instructions for simultaneously displaying the active graphics component in the first portion and the altered video information in the inactive portion.
