Abstract
A diffractive display for displaying multiple images, each at a unique view zone, includes multiple micro-pixels, each having micro-facets, each micro-facet having a surface normal non-parallel to the surface normal of other micro-facets of the micro-pixel, each micro-facet having a diffractive nano-structure array. Each diffractive nano-structure array has a viewing angle at which incident light is diffracted from the diffractive nano-structure array. The diffracted light has a hue and an intensity based on properties of the diffractive nano-structure array, and, for each of the images, each of the micro-pixels includes at least one diffractive nano-structure array for which the viewing angle corresponds to the view zone the image, such that each of the images is composed of the diffracted light from at least one diffractive nano-structure array from each of the micro-pixels.
