Multi-primary display with spectrally adapted back-illumination
First Claim
1. A device for displaying a color image comprising:
- an illumination source comprising a plurality of light-producing elements able to produce light of each of m different wavelength spectra, wherein m is equal to or greater than three;
an array of attenuating elements able to selectively attenuate the light produced by said illumination source according to an attenuation pattern corresponding to a gray-level representation of said color image; and
an array of color sub-pixel filter elements able to receive selectively attenuated light from said array of attenuating elements, each sub-pixel filter element able to transmit light of one of n different primary colors, wherein n is equal to or greater than four.
