Patent ID: 6972777

Claim:
An image display apparatus comprising: space modulation means for modulating incident light according to input display data and outputting the modulated incidence light; illumination means for illuminating said space modulation means with light; and projection means for projecting light emitted from said space modulation means upon an image display screen, wherein said illumination means repeats one illumination cycle having a plurality of periods, which include at least periods for illuminating said space modulation means with lights of first, second and third colors which are different from white and different from one another, and two discontinuous periods for illuminating said space modulation means with a white light, wherein the space modulation means modulates respectively the lights of the first, second and third colors and the white light, and wherein, during the one illumination cycle, the period for illuminating said space modulation means with the white light starts after each one of the periods for illuminating said space modulation means with the lights of at least two of the first, second and third colors, and before the period for illuminating said space modulation means with the light of the other color.
