Abstract
A method and apparatus for enabling power management of a flat-panel display is described. In one embodiment, a method involves detecting at least one display device power state and adjusting a backlight brightness in a display monitor in response to the detecting the at least one display power state. In one embodiment, a method further involves altering the brightness of a display image in order to maintain a display image quality when the backlight is adjusted.
Claims25
A method comprising:
- detecting at least one graphics accelerator power state;
- adjusting a backlight brightness in a display monitor in response to detecting the at least one graphics accelerator power state;
- adjusting a display image brightness in response to adjusting the backlight brightness to maintain a pre-determined display image quality represented by a relationship among a plurality of display image properties.
A method comprising:
- displaying a display image on a display monitor;
- detecting a display image brightness;
- adjusting the display image brightness by adjusting a display character brightness or a background brightness in response to detecting the display image brightness and detecting a power state of a graphics accelerator corresponding to the display image.
An apparatus comprising:
- a first unit to adjust a backlight brightness in response to detecting a graphics accelerator power state;
- a second unit to adjust a display image brightness in response to an adjustment of the backlight brightness.
A system comprising:
- a display monitor;
- a graphics accelerator to generate a display image on the display monitor, the display image having a character brightness and a background brightness;
- a first unit to adjust the character brightness and the background brightness in response to a change in power state of the graphics accelerator.
A machine-readable medium having stored thereon a set of instructions, which if executed by a machine cause the machine to perform a method comprising:
- detecting a first graphics accelerator power state;
- adjusting a backlight brightness in a display monitor in response to detecting the first graphics accelerator power state;
- and
- adjusting a display image brightness in response to adjusting the backlight brightness.
