Screen color calibration

1. An apparatus comprising:

a screen;

a calibration screen disposed within a computer;

an optical sensor adjacent to the calibration screen that measures a calibration color of the calibration screen, wherein the calibration screen is separate from the screen and has a color calibration within 5 percent of a screen color of the screen after 24 months;

a processor;

a memory that stores code executable by the processor to calibrate the screen color using the calibration color by:

determining whether the calibration color satisfies a color policy;

in response to the calibration color not satisfying the color policy, modifying calibration screen settings for the calibration screen; and

setting screen settings for the screen to the calibration screen settings.

2. The apparatus of claim 1 , wherein the calibration screen is a functional analog of the screen.

3. The apparatus of claim 1 , wherein in the calibration screen comprises m×n pixels, and at least one of m and n is less than 17.

4. The apparatus of claim 1 , wherein the optical sensor and the calibration screen are packaged together.

5. The apparatus of claim 1 , wherein the optical sensor and the calibration sensor are mounted on a circuit board.

6. The apparatus of claim 1 , wherein the calibration color comprises a calibration color temperature and a calibration color gamut.

7. The apparatus of claim 1 , wherein the screen color is calibrated in response to the calibration policy being satisfied, the calibration policy being satisfied by one or more of an expiration of a calibration time interval and a boot of the computer.

8. A method comprising:

measuring, by use of an optical sensor, a calibration color of a calibration screen disposed within a computer, wherein the calibration screen is separate from a screen and has a color calibration within 5 percent of a screen color of the screen after 24 months; and

calibrating, by use of semiconductor hardware, a screen color of the screen based on the calibration color by:

determining whether the calibration color satisfies a color policy;

in response to the calibration color not satisfying the color policy, modifying calibration screen settings for the calibration screen; and

setting screen settings for the screen to the calibration screen settings.

9. The method of claim 8 , wherein one or more of the calibration screen is a functional analog of the screen and the calibration screen is driven by a functional equivalent signal to a signal driving the screen.

10. The method of claim 8 , wherein in the calibration screen comprises m×n pixels, and at least one of m and n is less than 17.

11. The method of claim 8 , wherein the optical sensor and the calibration screen are packaged together.

12. The method of claim 8 , wherein the optical sensor and the calibration sensor are mounted on a circuit board.

13. The method of claim 8 , wherein the calibration color comprises a calibration color temperature and a calibration color gamut.

14. The method of claim 8 , wherein the screen color is calibrated in response to the calibration policy being satisfied, the calibration policy being satisfied by one or more of an expiration of a calibration time interval and a boot of the computer.

15. A program product comprising a non-transitory computer readable storage medium that stores code executable by a processor, the executable code comprising code to:

measure a calibration color of a calibration screen disposed within a computer using an optical sensor, wherein the calibration screen is separate from a screen and has a color calibration within 5 percent of a screen color of the screen after 24 months;

calibrate a screen color of the screen based on the calibration color by:

determining whether the calibration color satisfies a color policy;

in response to the calibration color not satisfying the color policy, modifying calibration screen settings for the calibration screen; and

setting screen settings for the screen to the calibration screen settings.

16. The program product of claim 15 , wherein the calibration screen is a functional analog of the screen.

17. An apparatus comprising:

a calibration screen disposed within a computer;

an optical sensor adjacent to the calibration screen that measures a calibration color of the calibration screen, wherein the calibration screen is separate from a screen and has a color calibration within 5 percent of a screen color of the screen after 24 months and calibrates a screen color of the screen based on the calibration color by:

determining whether the calibration color satisfies a color policy;

in response to the calibration color not satisfying the color policy, modifying calibration screen settings for the calibration screen; and

setting screen settings for the screen to the calibration screen settings.
