Extending the gamut color generation in a display

A method for extending a color gamut comprising:

• adding one or more primary colors lying outside a tristimulus color space triangle to a Red, Green, Blue (RGB) system;
• modulating light emitted by both light sources lying inside said tristimulus color space triangle and light sources lying outside said tristimulus color space triangle;
• and
• adding a non-tristimulus vertex to construct an extended-gamut polygon.

A method for extending a color gamut comprising:

• adding one or more primary colors lying outside a tristimulus color space triangle to a Red, Green, Blue (RGB) system;
• driving both light sources of primary colors lying inside said tristimulus color space triangle and light sources of said one or more primary colors lying outside said tristimulus color space triangle to provide light to a plurality of pixels;
• modulating light emitted by both light sources lying inside said tristimulus color space triangle and light sources lying outside said tristimulus color space triangle;
• and
• adding a non-tristimulus vertex to construct an extended-gamut polygon.
