Claim 14:
15. A method of multiview display operation comprising:
emitting a plurality of directional light beams using a color-tailored multibeam element comprising a plurality of color regions, each color region of the color region plurality emitting light having a color corresponding to a color of the color region;
diffusing the plurality of directional light beams using an optical diffuser to provide an image of each color region having an extent comparable to a size of the color-tailored multibeam element; and
modulating the plurality of directional light beams using an array of light valves to provide a multiview image, a light valve of the light valve array having a plurality of color sub-pixels with colors corresponding to the colors of color regions of the color region plurality,
wherein a diffusion angle of the optical diffuser is equal to a first product of a size of the color-tailored multibeam element and a refractive index of a medium between the color-tailored multibeam element and the light valve array divided by a second product of a number of color regions of a plurality of different color regions within the color-tailored multibeam element and a distance between the color-tailored multibeam element and the light valve array.
