Abstract
A multilayer static multiview display and method of multilayer multiview display operation provide a plurality of multiview images using diffractive scattering of light from guided light beams having different radial directions. The static multiview display includes a first multiview display layer configured to emit directional light beams representing a first multiview image by diffractive scattering light from a radial pattern of guided light beams within the first multiview display layer. The static multiview display further includes a second multiview display layer configured to emit directional light beams representing a second static multiview image by diffractive scattering light from a radial pattern of guided light beams within the second multiview display layer. The provided plurality of multiview images may include a composite color multiview image, a static multiview image, or an animated or quasi-static multiview image.
