Abstract

Numerous embodiments of a method and apparatus for a wide gamut color display are disclosed.

Claims

1. An apparatus comprising:

an electronic multicolor display;

said multicolor display having the capability to display an extended range of color of the color gamut of the human visible spectrum.

2. The apparatus of claim 1, wherein said display incorporates pixels capable of displaying at least four primary colors.

3. The apparatus of claim 2, wherein said pixels comprise four sub pixels wherein at least some respective sub pixels are capable of respectively displaying different primary colors.

4. The apparatus of claim 3, wherein said different primary colors comprise Red-Blue-Green-Cyan.

5. The apparatus of claim 2, wherein the materials comprising said pixels include light emitting polymers.

6. The apparatus of claim 2, wherein said pixels comprise liquid crystal material based pixels.

7. The apparatus of claim 2, wherein said display comprises a cathode-ray tube display (CRT)

8. A method comprising:

fabricating a plurality of pixels, wherein at least some of said pixels comprise at least four sub pixels.

9. The method of claim 8, wherein said at least four sub pixels respectively comprise a material capable of respectively displaying a respective one of at least four primary colors.

10. The method of claim 8, wherein said pixels are fabricated from light emitting polymers.

11. The method of claim 8, wherein said pixels are fabricated from liquid crystal material.

12. The method of claim 8, wherein said pixels are fabricated for use in a cathode ray tube display.

14. The method of claim 13, wherein said display comprises one or more pixels, wherein at least a portion of said pixels comprise at least four sub pixels.

15. The method of claim 13, wherein color converting comprises:

determining image color intensities for at least a portion of the pixels of said image in three primary color space;

multiplying at least a portion of said image color intensities with a plurality of coefficients; and

using the result of said multiplication to determine the image color intensities in four primary color space for the at least a portion of the pixels of said image.

16. The method of claim 15, wherein said coefficients are determined based at least in part on type of pixel material and type of display.

17. The method of claim 15, wherein the not less than four primary colors comprise Red-Blue-Green-Cyan.

18. The method of claim 15, wherein said display comprises a liquid crystal display (LCD).

19. The method of claim 15, wherein said display comprises a cathode-ray tube (CRT) display.

20. The method of claim 15, wherein said display comprises an electro luminescent polymer display.

21. The method of claim 15, wherein said image is coded on a computer system.

13. A method for displaying images, said method comprising:

converting color coding for an image from a three primary color space to a space having not less than four primary colors; and

using the converted color coding to display said image in said space having not less than four primary colors.

22. An article comprising:

a storage medium, said storage medium have stored thereon instructions, that, when executed, result in execution of a method for displaying images comprising;

converting color coding for an image from a three primary color space to a space having not less than four primary colors; and

using the converted color coding to display said image in said space having not less than four primary colors.

23. The article of claim 22, wherein said medium further has stored thereon instructions that, when executed, result in execution of a method for displaying images comprising:

determining image color intensities for at least a portion of the pixels of said image in three primary color space;

multiplying at least a portion of said image color intensities with a plurality of coefficients; and

using the result of said multiplication to determine the image color intensities in four primary color space for the at least a portion of the pixels of said image.

25. The system of claim 24, and further comprising:

said computing platform being further adapted to, in operation, perform the following;

determine image color intensities for at least a portion of the pixels of said image in three primary color space;

multiply at least a portion of said image color intensities with a plurality of coefficients; and

use the result of said multiplication to determine the image color intensities in four primary color space for the at least a portion of the pixels of said image.

24. A system for displaying not less than four primary colors comprising:

a platform;

said platform being adapted to, in operation, convert color coding for an image from three primary color space to a space having not less than four primary colors, and being adapted to use the converted color coding to display said image in said space having not less than four primary colors.
