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 a computing device, dynamically identifying a first subregion and a second subregion of a display of the computing device, wherein the display is backlit by backlighting components, and wherein content of a structured document is associated with each subregion;

by the computing device, increasing light intensity of one or more backlighting components that backlight the first subregion based on the content associated with the first subregion; and

by the computing device, decreasing light intensity of one or more backlighting components that backlight the second subregion based on the content associated with the second subregion, wherein the increasing and the decreasing are concurrent.

2. The method of claim 1, further comprising determining that no user input has been received by the computing device for a predetermined period of time, wherein the first subregion and the second subregion are dynamically identified in response to the determination that no user input has been received.

3. The method of claim 1, wherein the content associated with the first subregion comprises dynamic content of the structured document, and wherein the content associated with the second subregion comprises static content of the structured document.

4. The method of claim 1, wherein the content associated with the first subregion comprises a message received at the computing device.

5. The method of claim 4, further comprising determining a first location of a source of the message, wherein the increasing the light intensity is based on the first location being less than a predetermined distance from a second location of a user of the computing device.

6. The method of claim 1, wherein the first subregion and the second subregion are dynamically identified based on importance of the content associated with the respective subregion.

7. The method of claim 1, wherein the increasing the light intensity comprises maintaining the light intensity of the one or more backlighting components that backlight the first subregion.

8. The method of claim 1, wherein the decreasing the light intensity comprises turning off the one or more backlighting components that backlight the second subregion.

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

dynamically identify a first subregion and a second subregion of a display of a computing device, wherein the display is backlit by backlighting components, and wherein content of a structured document is associated with each subregion;

increase light intensity of one or more backlighting components that backlight the first subregion based on the content associated with the first subregion; and

decrease light intensity of one or more backlighting components that backlight the second subregion based on the content associated with the second subregion, wherein the increasing and the decreasing are concurrent.

10. The media of claim 9, further comprising determining that no user input has been received by the computing device for a predetermined period of time, wherein the first subregion and the second subregion are dynamically identified in response to the determination that no user input has been received.

11. The media of claim 9, wherein the content associated with the first subregion comprises dynamic content of the structured document, and wherein the content associated with the second subregion comprises static content of the structured document.

12. The media of claim 9, wherein the content associated with the first subregion comprises a message received at the computing device.

13. The media of claim 12, further comprising determining a first location of a source of the message, wherein the increasing the light intensity is based on the first location being less than a predetermined distance from a second location of a user of the computing device.

14. The media of claim 9, wherein the first subregion and the second subregion are dynamically identified based on importance of the content associated with the respective subregion.

15. The media of claim 9, wherein the increasing the light intensity comprises maintaining the light intensity of the one or more backlighting components that backlight the first subregion.

16. A system comprising:

one or more processors; and

a memory coupled to the processors comprising instructions executable by the processors, the processors operable when executing the instructions to;

dynamically identify a first subregion and a second subregion of a display of a computing device, wherein the display is backlit by backlighting components, and wherein content of a structured document is associated with each subregion;

increase light intensity of one or more backlighting components that backlight the first subregion based on the content associated with the first subregion; and

decrease light intensity of one or more backlighting components that backlight the second subregion based on the content associated with the second subregion, wherein the increasing and the decreasing are concurrent.

17. The system of claim 16, further comprising determining that no user input has been received by the computing device for a predetermined period of time, wherein the first subregion and the second subregion are dynamically identified in response to the determination that no user input has been received.

18. The system of claim 16, wherein the content associated with the first subregion comprises a message received at the computing device.

19. The system of claim 18, further comprising determining a first location of a source of the message, wherein the increasing the light intensity is based on the first location being less than a predetermined distance from a second location of a user of the computing device.

20. The system of claim 16, wherein the first subregion and the second subregion are dynamically identified based on importance of the content associated with the respective subregion.
