Abstract

A color display (i.e., multicolor computer display) employs four additive primary colors, namely, red, green, and blue and an additional cyan-based color referred to as “supercyan.” The primary color supercyan corresponds to light with a wavelength of about 500 nm and functions to extend the color gamut of a color display significantly beyond the green-blue axis of conventional color displays.

Claims

1. A multi-color computer display, comprising:

four primary colors from which a color gamut is displayed, the four primary colors including red, green, blue, and a cyan-based primary color.

2. The display of claim 1 in which the four primary colors are formed by four corresponding color filters associated with the display.

3. The display of claim 2 comprising an array of plural pixels and in which the four-color filters are formed as an arrangement sub-pixel color filters for each pixel in the array.

4. The display of claim 2 comprising an array of plural pixels and in which the four-color filters provide field-sequential color filtering in which the filters successively filter light corresponding to a common set of pixels.

5. The display of claim 2 in which the cyan-based primary color includes a wavelength of about 500 nanometers.

6. The display of claim 5 in which the cyan-based primary color is centered on a wavelength of about 500 nanometers and includes a spectral width of about 30 nanometers.

7. A multi-color computer display, comprising:

four primary colors from which a color gamut is displayed, the four primary colors including red, green, blue, and a cyan-based primary color including a wavelength of about 500 nanometers.

8. The display of claim 7 in which the four primary colors are formed by four corresponding color filters associated with the display.

9. The display of claim 8 comprising an array of plural pixels and in which the four-color filters are formed as an arrangement sub-pixel color filters for each pixel in the array.

10. The display of claim 8 comprising an array of plural pixels and in which the four-color filters provide field-sequential color filtering in which the filters successively filter light corresponding to a common set of pixels.

11. The display of claim 7 in which the cyan-based primary color is centered on a wavelength of about 500 nanometers and includes a spectral width of about 30 nanometers.

12. A multi-color computer display, comprising:

a color gamut with four points that define four vertices in a color space, one of the four points corresponding to a cyan-based primary color.

13. The display of claim 12 in which the cyan-based primary color includes a wavelength of about 500 nm.

14. The display of claim 13 in which the cyan-based primary color has a spectral width of about 30 nm.
