Abstract: A multiview backlight and a multiview display employ multibeam elements configured to provide a tilted plurality of light beams having different principal angular directions corresponding to different view directions of a plurality of views of the multiview display. Further, the tilted plurality of light beams has a tilt toward a center of a view zone of the multiview display to provide converging views. The multiview backlight includes a light guide and an array of the multibeam elements. The multiview display further includes multiview pixels that include view pixels to modulate the tilted plurality of light beams having the tilt and the different principal angular directions.

Abstract: A diffractive backlight system includes a light source and a plate light guide. A surface of the plate light guide is configured with a diffraction grating that couples light out of the plate light guide and concentrates the light into a localized region of space. The diffractive backlight system may be used with at least one light valve array to form a display that generates images for viewing in the localized region of space. The display may be incorporated in head-mounted displays in order to generate focused augmented or virtual reality images for wearers.

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: 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 backlight and display employ diffusion of directional light beams to provide an image of color regions of a color-tailored multibeam element having a size comparable to a size of the color-tailored multibeam element. The multiview backlight includes an array of array of color-tailored multibeam elements configured to provide the directional light beams and an optical diffuser configured to spread out directional light beams to provide the color region image. The multiview display includes an array of the color-tailored multibeam elements and the optical diffuser. The multiview display further includes an array of light valves configured to modulate the directional light beams as a multiview image.

Abstract: In a supersampling technique, an adjacent pair of pixels in a three-dimensional (3D) electronic display is driven based on angular combinations. In particular, a pixel in the pair is driven by an angular combination of a pixel in a 3D view of a 3D image and at least one product of a pixel in an intermediate 3D view and an associated weight. Moreover, the 3D views applied to the pair have different associated angular ranges with different principal angular directions, and the intermediate 3D view has an associated intermediate angular range with an intermediate principal angular direction that is between the principal angular directions. When viewing the 3D electronic display along a principal angular direction in the principal directions of the 3D view, a viewer sees the 3D view, and when viewing the 3D electronic display along the intermediate principal angular direction, the viewer sees the intermediate 3D view.

Abstract: A static multiview display and method of static multiview display operation provide a static multiview image using diffractive gratings to diffractively scatter light from guided light beams having different radial directions. The static multiview display includes a light guide configured to guide plurality of guided light beams and a light source configured to provide the guided light beam plurality having the different radial directions. The static multiview display further includes a plurality of diffraction gratings configured to provide from a portion of the guided light beams directional light beams having intensities and principal angular directions corresponding to view pixels of the static multiview image. The static multiview image has an arrangement of views configured to provide diagonal parallax that may facilitate viewing from a diagonal direction relative to the static multiview display.

Abstract: A method of aligning a multiview backlight with a light valve array of a multiview display employs an alignment pattern that includes unit cells spaced apart from one another and having view blocks corresponding to different views of the multiview display. The method of aligning includes establishing the alignment pattern on the light valve array, illuminating the light valve array using the multiview backlight to display the alignment pattern, and adjusting a relative position of the multiview backlight and the light valve array to minimize an error measure of the unit cells within the displayed alignment pattern. A multiview display backlight alignment system includes the multiview display and a positioning stage configured to adjust the relative position to minimize the error measure. An automated multiview display backlight alignment system further includes a feedback controller, the positioning stage being motorized.

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.
