Abstract
A static multiview display includes a plurality of light emitters offset in a longitudinal direction; a light guide configured to guide light in the longitudinal direction; a collimating light coupler configured to receive light from the light emitters and coupling the light to the light guide; and an array of diffraction gratings to extract light guided by the light guide to provide a multiview image having a direction that is a function of both color and a propagation angle of light guided by the light guide.
