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.

Abstract: Multiview displays include a reflective support structure located between a backlight and a screen. The backlight includes a plate light guide configured to couple out light that propagates within the plate light guide using multibeam elements. The reflective support structure reflects light incident on a portion of the surface that abuts the reflective support structure back into the plate light guide. The screen includes an array of multiview pixels configured to modulate coupled out light to create a multiview image.

Abstract: Multiview backlighting having a color-tailored emission pattern provides 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 color-tailored multibeam element. The color-tailored multibeam element is configured to provide emitted light having the 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. The color-tailored emission pattern corresponds to an arrangement of color sub-pixels of a view pixel in the multiview display.

Abstract: A backlight scattering element, multiview display, and method of backlight scattering element operation employ a high-index light guide layer in conjunction with a light guide and diffraction grating to provide emitted light. The backlight scattering element includes a light guide that guides light as guided light and a high-index light guide layer optically connected to the light guide and configured to extend a thickness of the light guide. The backlight scattering element also includes a diffraction grating adjacent to the high-index light guide layer to diffractively scatter out a portion of the guided light as emitted light. The multiview display includes a light guide having a first layer and a second layer, a refractive index of the second layer being greater than a refractive index of the first layer. The multiview display may modulate diffractively scattered out directional light beams to provide a multiview image.

Abstract: A multiview display includes an array of light valves having rows of a repeating plurality of color sub-pixels and arranged as a plurality of multiview pixels configured to modulate directional light beams as color pixels of views of a multiview image. A first row of the repeating plurality of color sub-pixels is offset from a second row of the repeating plurality of color sub-pixels in a row direction by an integer multiple of a width of a color sub-pixel. The offset of the first and second rows is configured to provide corresponding color sub-pixels in adjacent multiview pixels having different colors to mitigate color fringing associated with the color pixel of the multiview image. The multiview display further includes a light control film configured to control a view angle of the multiview image.
