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 diffractive multiview backlight and a multiview display employ an array of diffractive multibeam elements including a plurality of diffraction gratings configured to provide a plurality of light beams having different principal angular directions corresponding to different view directions of the multiview display. The display includes multiview pixels that include sub-pixels. A size of the diffractive multibeam element of the array is comparable to a size of a sub-pixel in a multiview pixel of the multiview display.

Abstract: Multiview backlighting employs a plasmonic multibeam element having a color-tailored emission pattern to provide directional light beams corresponding to a plurality of different views of a multiview image. A multiview backlight includes a light guide configured to guide light as guided light and a plasmonic multibeam element. The plasmonic multibeam element includes a plasmonic material and is configured to provide emitted light having a color-tailored emission pattern from the guided light. The emitted light includes a plurality of directional light beams having different principal angular directions corresponding to respective different view directions of a multiview display and the color-tailored emission pattern corresponds to an arrangement of color sub-pixels of a view pixel in the multiview display.
