Abstract

Aspects of the present invention relate to methods and systems for controlling power consumption with a power controlling display device. Some aspects relate to a power controlling display device that receives a notification of a power control event that may control internal display components as well as connected power consuming devices. Some aspects relate to methods and systems for automatically compensating a displayed image when display backlight levels are modified in response to a power control event.

Claims

1. A method for regulating power consumption with a power-controllable display device (PCDD), said method comprising:

a) selecting a backlight level for said PCDD, wherein said selecting is based on efficient power consumption, and wherein said PCDD comprises a processor and a memory and wherein said PCDD is connected to an external power source managed by a power supplier charging a fee for power received from said external power source based on a variable rate;

b) adjusting image content to be displayed by using said backlight level so as to compensate for said backlight level;

c) receiving a notification of a power control event at said PCDD, wherein said notification is received from said power supplier and said power control event relates to said variable rate; and

d) automatically, without manual input, scaling said backlight level in response to said power control event.

2. The method as described in claim 1 further comprising:

a) prompting a user for user preference data related to power consumption by displaying a prompt on a display of said PCDD;

b) receiving user preference data related to power consumption at said PCDD via a remote control device that controls said PCDD;

c) determining a display control schedule, comprising device control data, for said PCDD, said display control schedule being based on said notification of a power control event and said user preference data; and

d) further adjusting said image content according to said display control schedule.

3. The method as described in claim 1 wherein said receiving a notification of a power control event occurs over a wireless network connection.

4. The method as described in claim 1 wherein said receiving a notification of a power control event occurs over an RF television channel.

5. The method as described in claim 1 wherein said receiving a notification of a power control event occurs over a cable television channel.

6. The method as described in claim 1 wherein said notification of a power control event is received from a power supplier.

7. A method for regulating power consumption with a power-controllable display device (PCDD), said method comprising:

a) receiving a notification of a power control event at said (PCDD), wherein said PCDD comprises a display for displaying an image, wherein said PCDD is connected to an external power source managed by a power supplier charging a fee for power received from said external power source based on a variable rate, wherein said notification is received from said power supplier and said power control event relates to said variable rate;

b) automatically, without manual input, adjusting image content to be displayed on said display in response to said power control event;

c) wherein said adjusting comprises the application of a tone scale adjustment to said image content.

8. The method as described in claim 7 further comprising:

a) prompting a user for user preference data related to power consumption by displaying a prompt on a display of said PCDD;

b) receiving user preference data related to power consumption at said PCDD via a remote control device that controls said PCDD;

c) determining a display control schedule, comprising device control data, for said PCDD, said display control schedule being based on said notification of a power control event and said user preference data; and

d) further adjusting said image content according to said display control schedule.

9. The method as described in claim 7 wherein said receiving a notification of a power control event occurs over a wireless network connection.

10. The method as described in claim 7 wherein said receiving a notification of a power control event occurs over an RF television channel.

11. The method as described in claim 7 wherein said receiving a notification of a power control event occurs over a cable television channel.

12. The method as described in claim 7 wherein said notification of a power control event is received from a power supplier.

13. A method for regulating power consumption with a power-controlled display device (PCDD), said method comprising:

a) receiving a notification of a power control event at said (PCDD), wherein said PCDD comprises a display for displaying an image, wherein said PCDD is connected to an external power source managed by a power supplier charging a fee for power received from said external power source based on a variable rate, wherein said notification is received from said power supplier and said power control event relates to said variable rate; and

b) automatically, without manual input, reducing a display brightness setting on said display in response to said power control event.

14. The method as described in claim 13 further comprising:

a) prompting a user for user preference data related to power consumption by displaying a prompt on a display of said PCDD;

b) receiving user preference data related to power consumption at said PCDD via a remote control device that controls said PCDD;

c) determining a display control schedule, comprising device control data, for said PCDD, said display control schedule being based on said notification of a power control event and said user preference data; and

d) further adjusting said display brightness of said PCDD according to said display control schedule.

15. The method as described in claim 13 further comprising compensating an image to compensate for the reduced said brightness setting.

16. The method as described in claim 13 wherein the step of reducing a display brightness setting comprises analyzing image distortion at a plurality of brightness settings.

17. The method as described in claim 13 wherein said receiving a notification of a power control event occurs over an RF television channel.
