Abstract

In one embodiment, a method includes, by software of a computing device, dynamically identifying a particular region of a display of the computing device. The method also includes, by the software and through a device driver of the computing device, dynamically adjusting one or more particular ones of a plurality of backlighting components of the display associated with the particular region.

Claims

1. A method comprising:

by software on a computing device, dynamically identifying a particular region of a display of the computing device; and

by the software and through a device driver of the computing device, dynamically adjusting one or more particular ones of a plurality of backlighting components of the display associated with the particular region.

2. The method of claim 1, wherein the software is an application or an operating system (OS) on the computing device.

3. The method of claim 1, wherein the plurality of backlighting components are light-emitting diodes (LEDs).

4. The method of claim 1, wherein dynamically adjusting one or more particular ones of the plurality of backlighting components comprises accessing an application programming interface (API) to cause a device driver of the plurality of backlighting components to adjust the one or more particular ones of the plurality of backlighting components.

5. The method of claim 1, wherein dynamically adjusting one or more particular ones of the plurality of backlighting components comprises adjusting their intensity.

6. The method of claim 1, wherein dynamically adjusting one or more particular ones of the plurality of backlighting components comprises adjusting their color.

7. The method of claim 1, further comprising instructing the display to refresh only the particular region.

8. One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

dynamically identify a particular region of a display of a computing device; and

through a device driver of the computing device, dynamically adjust one or more particular ones of a plurality of backlighting components of the display associated with the particular region.

9. The media of claim 8, wherein the software is an application or an operating system (OS) on the computing device.

10. The media of claim 8, wherein the plurality of backlighting components are light-emitting diodes (LEDs).

11. The media of claim 8, wherein to dynamically adjust one or more particular ones of the plurality of backlighting components, the software is configured to access an application programming interface (API) to cause a device driver of the plurality of backlighting components to adjust the one or more particular ones of the plurality of backlighting components.

12. The media of claim 8, wherein to dynamically adjust one or more particular ones of the plurality of backlighting components, the software is configured to adjust their intensity.

13. The media of claim 8, wherein to dynamically adjust one or more particular ones of the plurality of backlighting components, the software is configured to adjust their color.

14. The media of claim 8, the software is further configured to instruct the display to refresh only the particular region.

15. An apparatus comprising:

a display; and

one or more computer-readable non-transitory storage media coupled to the display and embodying software that is operable when executed to;

dynamically identify a particular region of the display; and

through a device driver of the apparatus, dynamically adjust one or more particular ones of a plurality of backlighting components of the display associated with the particular region.

16. The apparatus of claim 15, wherein the software is an application or an operating system (OS) on the apparatus.

17. The apparatus of claim 15, wherein the plurality of backlighting components are light-emitting diodes (LEDs).

18. The apparatus of claim 15, wherein to dynamically adjust one or more particular ones of the plurality of backlighting components, the software is configured to access an application programming interface (API) to cause a device driver of the plurality of backlighting components to adjust the one or more particular ones of the plurality of backlighting components.

19. The apparatus of claim 15, wherein to dynamically adjust one or more particular ones of the plurality of backlighting components, the software is configured to adjust their intensity.

20. The apparatus of claim 15, wherein to dynamically adjust one or more particular ones of the plurality of backlighting components, the software is configured to adjust their color.
