A display system (10) for digital color images using six color light sources (12) or two or more multicolor LED arrays (212, 213) or OLEDs (220, 222) to provide an expanded color gamut. Apparatus (10) uses two or more spatial light modulators (20, 21), which may be cycled between two or more color light sources (12) or LED arrays (212, 213) to provide a six-color display output. Pairing of modulated colors using relative luminance helps to minimize flicker effects. |

DETAILED DESCRIPTION It is an object of the present invention to provide a display apparatus for forming, from digital data, a color image having a broad color gamut.
With this object in mind, the present invention provides an apparatus for display of a color image from digital data, the apparatus comprising: (a) a first modulation system for providing a first modulated beam, the first modulation system comprising: (a1) a first spatial light modulator for modulating a first incident light beam in order to form the first modulated beam according to the digital data; (a2) a first light source for providing a first color beam as the first incident light beam; (a3) a second light source for providing a second color beam as the first incident light beam; (a4) a third light source for providing a third color beam as said first incident light beam; (b) a second modulation system for providing a second modulated beam, the second modulation system comprising: (b1) a second spatial light modulator for modulating a second incident light beam in order to form the second modulated beam according to the digital data; (b2) a fourth light source for providing a fourth color beam as said second incident light beam; (b3) a fifth light source for providing a fifth color beam as the second incident light beam; (b4) a sixth light source for providing a sixth color beam as the second incident light beam; and (c) an optical combiner for directing the first modulated beam and the second modulated beam for projection onto a surface by a projection lens.
A feature of the present invention is the use of light sources having a sufficient degree of spectral purity in order to provide a broad color gamut.
LEDs, widely available, inexpensive, nearly monochromatic, and having a long component life, are used in the preferred embodiment.
LEDs are inherently small, bright, and low-power devices, with fast switching times.
There is no need for splitting or filtering of the LED light when directed toward an LCD spatial light modulator, and no consequent filter losses
