METHOD AND SYSTEM FOR REDUCING POWER CONSUMPTION IN A DISPLAY
A method and system for reducing power consumption in a display includes driving a display comprising a plurality of display elements having selectable resolution, wherein the display device is configured to operate at a plurality of selectable operational modes. In a first operational mode, data at a first resolution is provided to the display at a first data rate, and in a second operational mode, data at a second resolution is provided to the display at a second data rate.
1 . An apparatus for displaying image data, the apparatus comprising:
a display device comprising a plurality of display elements having selectable resolution, wherein the display device is configured to operate at a plurality of selectable operational modes; and
an image data source configured to provide image data to the display device such that in a first operational mode, data at a first resolution is provided at a first data rate, and in a second operational mode, data at a second resolution is provided at a second data rate, wherein the first and second resolutions are different.
2 . The apparatus of claim 1 , wherein in at least one of said operational modes, said display device displays a reduced color gamut as compared to said first operational mode.
3 . The apparatus of claim 1 , further comprising a communications network, wherein said image data source is configured to provide said image data over said communications network.
4 . The apparatus of claim 3 , wherein said image data source is configured to control said operational mode.
5 . The apparatus of claim 3 , wherein the operational modes are selectable based at least in part on a data rate of said communications network.
6 . The apparatus of claim 5 , wherein the operational modes are selectable based at least in part on a data rate utilized by said communications network.
7 . The apparatus of claim 3 , wherein the operational modes are selectable based at least in part on power data of the display device.
8 . The apparatus of claim 3 , wherein the operational modes are selectable based at least in part on stored user preferences.
9 . The apparatus of claim 1 , wherein in at least one of said operational modes, said display device displays a reduced gray scale as compared to the first operational mode.
10 . The apparatus of claim 1 , wherein at least one of the operational modes comprises re-setting display states of less than all of the display elements.
11 . The apparatus of claim 10 , wherein the image data source is further configured to provide a display state to re-set a remaining portion of the display elements.
12 . The apparatus of claim 10 , wherein said less than all of the display elements comprise a first set of rows.
13 . The apparatus of claim 10 , wherein the image data source is further configured to provide filtered image data so that image data for the display elements that are not re-set is not provided.
14 . The apparatus of claim 1 , wherein said image data comprises motion picture data.
15 . The apparatus of claim 1 , wherein the second operational mode corresponds to reduced display element resolution as compared with the first operational mode, wherein the first operational mode includes displaying image data in a display region of the display device, and wherein the second operational mode includes displaying image data at a reduced display element resolution without changing the size of the display region.
16 . A method of displaying image data, said method comprising:
selecting an operational mode for a display device, the display device comprising a plurality of display elements having selectable resolution, wherein the display device is configured to operate at a plurality of selectable operational modes; and
providing image data to the display device such that in a first operational mode, data at a first resolution is provided at a first data rate, and in a second operational mode, data at a second resolution is provided at a second data rate, wherein the first and second resolutions are different.
17 . The method of claim 16 , wherein in at least one of said operational modes, said display device displays a reduced color gamut as compared to said first operational mode.
18 . The method of claim 16 , further comprising selecting an operational mode based at least in part on a data rate of said communications network.
19 . An apparatus for displaying image data, the apparatus comprising:
means for selecting an operational mode for a display device, the display device comprising a plurality of display elements having selectable resolution, wherein the display device is configured to operate at a plurality of selectable operational modes; and
means for providing image data to the display device such that in a first operational mode, data at a first resolution is provided at a first data rate, and in a second operational mode, data at a second resolution is provided at a second data rate, wherein the first and second resolutions are different.
20 . The apparatus of claim 19 , wherein in at least one of said operational modes, said display device displays a reduced color gamut as compared to said first operational mode.
