Abstract: A mode-selectable backlight and display employ a plurality of directional scattering features to provide emitted light. The mode-selectable backlight includes a light guide, a first directional scattering feature to provide first emitted light from guided light having a first propagation direction within the light guide in a first operational mode, and a second directional scattering feature to provide second light from guided light having a second propagation direction within the light guide in a second operational mode. The second emitted light comprises a plurality of directional light beams having different principal angular directions from one another and the first propagation direction differing from the second propagation direction. The mode-selectable display further includes a plurality of light sources to provide the guided light and an array of light valves configured to modulate the emitted light as a displayed image.

Abstract: A mode-switchable backlight and mode-switchable privacy display provide narrow-angle emitted light during a first mode and broad-angle emitted light in a second mode, the broad-angle emitted light being a combination of the narrow-angle emitted light and bidirectional emitted light. The mode-switchable backlight includes a first directional backlight and a second directional backlight. The first directional backlight is configured to provide the narrow-angle emitted light during both of the first mode and second mode, while the second directional backlight is configured to provide the bidirectional emitted light exclusively during the second mode. The mode-switchable privacy display includes an array of light valves configured to modulate the narrow-angle emitted light as a private displayed image during the first or privacy mode and to modulate broad-angle emitted light as a public displayed image during the second or public mode.

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: 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.

Abstract: Dual-direction collimation and a dual surface collimator provide dual-direction collimated light at a non-zero propagation angle. The dual surface collimator includes an entrance surface and a reflector surface each having a curved shape. The entrance surface is configured to refract incident light and the reflector surface is configured to reflect the refracted light back toward the entrance surface. The entrance surface is further configured to re-reflect the reflected light by total internal reflection toward an output aperture. Curved shapes and relative orientation of the entrance and reflector surfaces, in combination, are configured to convert the incident light into dual-direction collimated light having the non-zero propagation angle. A three-dimensional (3D) display includes the dual surface collimator, a plate light guide and an array of multibeam diffraction gratings to provide a plurality of light beams corresponding to different 3D view of the display.

Abstract: A head-up display and a three-dimensional (3D) head-up display system provide a plurality of different views of an image combined with a view of a physical environment to an eye box as a combined image to be viewed by a user. The head-up display includes a multibeam diffraction grating-based display configured to provide the different views and an optical combiner configured to relay the different views to the eye box along with the physical environment view. The different views provided by the 3D head-up display system represent different perspective views of a 3D image.
