Abstract

A display device including: a display screen having first region and second region, the first region having a first pixel density and the second region having a second pixel density, the second pixel density being higher than the first pixel density, an input for receiving image data, a power source; and wherein the display screen is operable in a full screen mode in which an image is displayed in both the first region and the second region and a reduced screen mode in which power to the first region is turned off and the image is displayed in the second region.

Claims (33)

1. A method, comprising:

illuminating a first region and a second region of a display screen of a device to display a first image, the first region having a first pixel density and the second region having a second pixel density that is greater than the first pixel density, wherein the first image is displayed at a same first resolution in the first region and the second region;

receiving a power conservation signal in response to a function performed by an application running on the device; and

in response to receiving the power conservation signal, updating illumination of the display screen to display a second image at a second resolution in the second region, the second resolution being higher than the first resolution and higher than a maximum image resolution based on the first pixel density.

2. The method of claim 1 , wherein updating illumination comprises at least one of shutting down power to the first region, operating the first region at a lower power, or operating the first region in a monochromatic mode.

3. The method of claim 2 , further comprising operating the second region at a lower power.

4. The method of claim 1 , wherein updating illumination comprises:

turning off power to the first region; and

wherein the first image is displayed as the second image in the second region with a resolution that is greater than the first resolution.

5. The method of claim 1 , wherein the second region is centrally located relative to the first region.

6. The method of claim 1 , wherein the function comprises the application launching a separate window.

7. A device, comprising:

a display configured to illuminate a first region and a second region of a display screen of a device to display a first image, the first region having a first pixel density and the second region having a second pixel density that is greater than the first pixel density, wherein the first image is displayed at a same first resolution in the first region and the second region;

one or more processors configured to receive a power conservation signal in response to a function performed by an application running on the device; and

the display further configured to, in response to receiving the power conservation signal, update illumination of the display screen to display a second image at a second resolution in the second region, the second resolution being higher than the first resolution and higher than a maximum image resolution based on the first pixel density.

8. The device of claim 7 , wherein update illumination comprises at least one of shut down power to the first region, operate the first region at a lower power, or operate the first region in a monochromatic mode.

9. The device of claim 8 , the display further configured to operate the second region at a lower power.

10. The device of claim 7 , wherein update illumination comprises:

turn off power to the first region; and

wherein the first image is displayed as the second image in the second region with a resolution that is greater than the first resolution.

11. The device of claim 7 , wherein the second region is centrally located relative to the first region.

12. The device of claim 7 , wherein the function comprises the application launching a separate window.

13. A non-transitory computer readable medium storing instructions to cause a processor to perform operations comprising:

illuminating a first region and a second region of a display screen of a device to display a first image, the first region having a first pixel density and the second region having a second pixel density that is greater than the first pixel density, wherein the first image is displayed at a same first resolution in the first region and the second region;

receiving a power conservation signal in response to a function performed by an application running on the device; and

in response to receiving the power conservation signal, updating illumination of the display screen to display a second image at a second resolution in the second region, the second resolution being higher than the first resolution and higher than a maximum image resolution based on the first pixel density.

14. The computer readable medium of claim 13 , wherein updating illumination comprises at least one of shutting down power to the first region, operating the first region at a lower power, or operating the first region in a monochromatic mode.

15. The computer readable medium of claim 14 , the instructions further comprising operating the second region at a lower power.

16. The computer readable medium of claim 13 , wherein updating illumination comprises:

turning off power to the first region; and

wherein the first image is displayed as the second image in the second region with a resolution that is greater than the first resolution.

17. The computer readable medium of claim 13 , wherein the second region is centrally located relative to the first region.

18. The computer readable medium of claim 13 , wherein the function comprises the application launching a separate window.
