3. The computing system defined in claim 1 wherein the history data indicates regions of the OLED display having damaged pixels.

4. The computing system defined in claim 1 wherein the history data indicates priority at which further usage of identified pixels should be avoided due to usage across pre-identified threshold levels.

5. The computing system defined in claim 1 wherein the processor is operable to manipulate the content by using one or both of:

one or more damage-onset-avoidance techniques; and

one or more compensation techniques that are applicable after onset of pixel damage, to render content for display.

6. The computing system defined in claim 1 wherein the processor is operable to manipulate the content by adjusting pixel usage to reduce usage of locations in the OLED display with damaged pixels or pixels used more frequently than other locations in the OLED display.

7. The computing system defined in claim 1 wherein the processor is operable to manipulate the content in such a way as to make usage of pixels of the OLED display occur more balanced over time.

8. The computing system defined in claim 1 wherein the processor is operable to manipulate the content by one or more of a group consisting of:

moving content designated for display on a first portion of the OLED display to a second portion of the OLED display;

changing content; and

selecting color for content.

9. The computing system defined in claim 8 wherein selecting a color for content comprises changing color intensity of content to be displayed.

10. The computing system defined in claim 1 wherein the one or more processors are operable to execute one or more applications, which when executed by the one or more processors, are operable to generate content for display based on at least a portion of a damage signature representing pixel damage that has occurred with the OLED display, the at least a portion corresponding to a location on the display at which a window generated by the application is to be displayed.

11. The computing system defined in claim 10 wherein the one or more processors are operable to:

analyze history data of pixels of the OLED display periodically to update the damage signature; and

provide the damage signature to an operating system (OS).

12. The computing system defined in claim 11 wherein the processor is operable to execute an OS, which provides the damage signature to the one or more applications, which use the damage signature to modify one or more of content placement and color choice.

13. The computing system defined in claim 11 wherein the processors is operable to execute a device driver that analyzes the history data and provides the damage signature to the OS.

14. The computing system defined in claim 1 wherein the processor is operable to execute one or more applications, which when executed by the processor, are operable to generate content and execute one or more composition managers in the operating system to compose an output for the OLED display using content from the one or more applications based on at least a portion of a damage signature representing pixel damage that has occurred with the OLED display.

15. The computing system defined in claim 14 wherein the one or more composition managers in the OS using the damage signature are operable to divide a graphical user interface (GUI) element into multiple portions and relocate one or more the plurality of portions to a new location on the OLED display other than their originally designated location, dynamically relocate the GUI element, or dynamically change one or more colors of a graphical representation of a file or program.

16. The computing system defined in claim 10 wherein the damage signature indicates priority levels assigned to different regions of the screen based on damage that has occurred to influence future use of each of the different regions.

17. The computing system defined in claim 10 wherein the damage signature includes data specifying specific sub-pixels to be favored for future use given the damage that has occurred.

18. The computing system defined in claim 10 wherein the processor is operable to execute an operating system that modifies the content based on the damage signature.
