Abstract

A display device includes power management by including a first input suitable to receive electrical power from an outlet for providing power for the operation of the display device. The display device includes a second input, separate from the first input, suitable to receive electrical power from an external battery source for providing power for the operation of the display device. The display device includes an internal battery source enclosed within the display device suitable for providing power for the operation of the display device. A source select is enclosed within the display device that selects power from at least one of the first input, the second input, and the internal battery for providing power for the operation of the display device. A processor receives video content from a video source and selectively modifies a backlight of the display device based upon the power source selected by the source select in such a manner as to reduce the power consumption of the display device. The processor may additionally change the media playback behavior to decode and playback only some of the video frames to reduce the power consumption of decoder and display device.

Claims

1. A display device including power management comprising:

(a) said display device including a first input suitable to receive electrical power from an outlet for providing power for the operation of said display device;

(b) said display device including a second input suitable to receive electrical power from an external battery source for providing power for the operation of said display device, where said first input to said display device and said second input to said display device are spaced apart from one another, and interconnected such that said external battery source may be recharged when said first input receives power from said outlet;

(c) said display device including an internal battery source enclosed within said display device suitable for providing power for the operation of said display device;

(d) a source select enclosed within said display device that selects power from at least one of said first input, said second input, and said internal battery for providing power for the operation of said display device;

(e) a processor that receives video content from a video source and selectively modifies a backlight of said display device based upon the power source selected by said source select in such a manner as to reduce the power consumption of said display device;

(f) wherein said backlight is modified based upon a signal from said external battery source provided to said second input, apart from said electrical power from said external battery source, wherein said signal provides an estimate of the available battery power charge level of said external battery source.

2. The display device of claim 1 wherein said outlet receives power from a utility.

3. The display device of claim 1 wherein said display device includes an attached power cord interconnecting said display device to said outlet.

4. The display device of claim 1 wherein said external battery source includes an inverter.

5. The display device of claim 4 wherein inverted power from said external battery source is provided to said second input.

6. The display device of claim 1 wherein said internal battery source is rechargeable.

7. The display device of claim 6 wherein power from said first input is capable of being used to recharge said internal battery source.

8. The display device of claim 6 wherein power from said second input is capable of being used to recharge said internal battery source.

9. The display device of claim 1 wherein said source select selects power from said first input if power is available from said first input to the exclusion of said second input and said internal battery.

10. The display device of claim 1 wherein said source selects power from said second input if power is available from said second input and power is not available from said first input and to the exclusion of said internal battery.

11. The display device of claim 1 wherein said source selects power from said internal battery if power is available from said internal battery and power is not available from said first input and said second input.

12. The display device of claim 1 wherein said source selects power from said internal battery if power is available from said internal battery and power Is not available from said first input and independent of whether power is available from said second input.

13. The display device of claim 1 wherein said processor receives said video content from an antenna.

14. The display device of claim 1 wherein said processor receives said video content from a digital video source.

15. The display device of claim 1 wherein said processor decodes only a selected subset of available video frames.

16. The display device of claim 1 wherein said processor only provides audio to a selected subset of available audio channels.

17. The display device of claim 1 further including a solar panel.

18. The display device of claim 17 wherein said solar panel is movably engaged with said display device.

19. The display device of claim 18 wherein said solar panel is movable to a position substantially flat with respect to at least one of the back and the front of the display.

20. The display device of claim 17 wherein said solar panel include an antenna for said display device.

21. The display device of claim 17 wherein said solar panel is movably engaged using a motor with said display device.

22. The display device of claim 17 wherein said solar panel is integrated on the front of said display device.

23. The display device of claim 17 wherein energy from said solar panel is used as a basis of said processor to said reduce said power consumption of said display device.
