Abstract: Multiview backlighting employs a fluorescent 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 fluorescent multibeam element. The fluorescent multibeam element includes a fluorescent material and is configured to provide emitted light having a color-tailor emission pattern from the guided light. The emitted light including 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: A light source configured to provide output light having a bifurcated emission pattern includes an optical emitter configured to emit light and a emission control layer. The emission control layer includes a first plurality of light-blocking elements spaced apart from one another in a vertical direction at an output aperture of the light source and a second plurality of light-blocking elements displaced from the output aperture and interleaved with the first plurality. The emission control layer is configured to transmit a portion of the emitted light through gaps between the light-blocking elements to provide the output light having the bifurcated emission pattern in the vertical direction. A multiview backlight includes the light source along with a light guide and an array of multibeam elements to provide a plurality of directional light beams using the output light having the bifurcated emission pattern.

Abstract: A multi-zone backlight and multi-zone multiview display with multiple zones selectively provide broad-angle emitted light corresponding to a two-dimensional (2D) image and directional emitted light corresponding to a multiview image to each zone of the multiple zones. The multi-zone backlight includes broad-angle backlight to provide the broad-angle emitted light and a multiview backlight to provide the directional emitted light. Each of the broad-angle backlight and the multiview backlight is divided into first zone and a second zone that may be independently activated to provide the broad-angle emitted light and multiview emitted light, respectively. The multi-zone includes the broad-angle backlight and the multiview backlight and further includes an array of light valves configured to modulate the broad-angle emitted light as a two-dimensional image and the directional emitted light as a multiview image on a zone-by-zone basis.

Abstract: A dual view zone backlight and dual-mode display employ a first backlight region including a directional emitter to provide directional emitted light toward a first view zone and a second backlight region including a broad-angle emitter to provide broad-angle emitted light toward the first and a second view zone in a first mode. The dual-mode display includes a second backlight to provide broad-angle light toward both the first view zone and the second view zone in a second mode.

Abstract: A backlight and a multiview display employ a light guide having angle-preserving scattering feature and a grating spreader. The angle-preserving scattering feature is configured to scatter a portion of guided light out of the light guide as emitted light. The grating spreader includes a diffraction grating and is configured to convert light provided by a light source into spatio-angularly homogenous light to be guided as the guided light. The multiview display includes an array of light valves as well as the angle-preserving scattering feature that includes a multibeam element having a size that is comparable to a size of a light valve of the light valve array.

Abstract: A near-eye display and a binocular near-eye display system provide a plurality of different views of a multiview image to different locations within an eye box to impart focus depth cues to a user. The near-eye display includes a multibeam element-based display configured to provide the different views and an optical system configured to relay the different views to the different locations within the eye box. The binocular near-eye display system includes a pair of the multibeam element-based displays and a binocular optical system configured to provide and relay a pair of multiview images as a stereoscopic image pair representing a three-dimensional (3D) scene to a corresponding pair of laterally displaced eye boxes.

Abstract: A backlit transparent display and a transparent display system provide a displayed image while enabling a background scene to be visible through the display. The backlit transparent display includes a light guide, a plurality of scattering elements, and an array of light valves configured to modulate emitted light scattered from the light guide to provide modulated emitted light representing a displayed image. Transparency of the backlit transparent display is configured to enable the background scene to be visible through the backlit transparent display. The transparent display system includes the array of light valves and a transparent backlight. The transparent display system is configured to provide the displayed image as superimposed on the background scene visible through the transparent display system.

Abstract: A light source includes an optical emitter configured to emit light toward an output aperture of the light source. The light source further includes a partially reflective layer at the output aperture. The partially reflective layer is configured to receive the emitted light from the optical emitter and to reflect a portion of the received light as reflected light. The light source additionally includes a scattering medium located between the partially reflective layer and the optical emitter. The scattering medium is configured to scatter the reflected light as scattered light having a different direction from the reflected light. A portion of the scattered light is redirected toward the partially reflective layer as recycled light to be emitted from the light source. A multiview backlight that employs the light source is also provided, along with a method for operating the light source.
