Claim 0:
1. A multicolor static multiview display comprising:
a plate light guide;
a multicolor light source configured to provide a plurality of guided light beams comprising a selectable color and having different radial directions from one another within the plate light guide; and
an array of multiview pixels configured to provide a plurality of different views of a color static multiview image, a multiview pixel comprising a plurality of diffraction gratings configured to diffractively couple out light from the guided light beam plurality to provide directional light beams representing color view pixels of the multiview pixel, at least two directional light beams having different intensities,
wherein a principal angular direction of a directional light beam provided by a diffraction grating of the diffraction grating plurality is a function of one or both of a grating pitch of the diffraction grating and a grating orientation of the diffraction grating, the one or both of the grating pitch and the grating orientation being a function of a relative location of the diffraction grating and the light source, and wherein a color of the directional light beam is determined by the selectable color.
