Abstract: A unilateral backlight and a unilateral multiview display employ an array of unilateral diffractive elements configured to provide directional light beams having a unilateral direction. A unilateral diffractive element of the unilateral diffractive element array comprises a slanted diffraction grating configured to provide a directional light beam by diffractive scattering of light guided in a light guide. The unilateral multiview display further includes light valves configured to modulate a plurality of directional light beams as multiview image having the unilateral direction.

Abstract: A grating-coupled light guide concentrates light and diffractively redirects the concentrated light at a non-zero propagation angle as guided light having a predetermined spread angle. The grating-coupled light guide includes a light guide, an optical concentrator, and a grating coupler. The optical concentrator is configured to concentrate light from a light source as concentrated light and the grating coupler is configured to diffractively redirect the concentrated light into the light guide as the guided light. Characteristics of the optical concentrator and grating coupler are configured in combination to determine the non-zero propagation angle and predetermined spread angle. A grating-coupled display system further includes an array of light valves configured to modulate emitted light as a displayed image.

Abstract: A static multiview display and method employ an array of diffraction gratings to provide a multiview image having a direction that is a function of both color and a propagation angle of a collimated guided light beam. The static multiview display includes a light guide configured to guide light in a longitudinal direction and a light source configured to provide the collimated guided light beam, the propagation angle within the light guide being determined by a longitudinal offset of an optical emitter of the light source. The static multiview display further includes the array of diffraction gratings are configured to scatter out a portion of the collimated guided light beam as a plurality of directional light beams representing the multiview image.
