Abstract: A multiview display employs an array of multibeam elements configured to provide directional light beams having different principal angular directions corresponding to different view directions of the multiview display. Moreover, the multiview display includes an array of light valves configured to modulate the directional light beams as a multiview image to be displayed by the multiview display, where a multiview pixel of the multiview display includes a set of light valves of the light valve array corresponding to a multibeam element of the multibeam element plurality and being configured to modulate directional light beams from the multibeam element. Furthermore, a shape of the multiview pixel is dynamically reconfigurable to provide the multiview image having a dynamic field of view (FOV). The FOV may be modified based on a monitored orientation of the multiview display, a monitored position of a user relative to the multiview display, or both.

Abstract: A multiview backlight, multiview display, and method of multiview backlight operation include reflective multibeam elements configured to provide emitted light having directional light beams with directions corresponding to view directions of a multiview image. The multiview backlight includes a light guide configured to guide light and an array of the reflective multibeam elements. Each reflective multibeam element includes a plurality of reflective sub-elements and is configured to reflectively scatter out a portion of the guided light as the emitted light. The multiview display includes the multiview backlight and an array of light valves to modulate the directional light beams to provide the multiview image. Each reflective sub-element protrudes from a guiding surface of the light guide by a respective protrusion distance. At least some of the protrusion distances can vary as a function of distance along a length of the light guide.

Abstract: Systems and methods are directed to a camera system configured to capture a multiview image of an object along an arc. Each camera in the camera system may correspond to a common field of view. In addition, a computing system coupled to the camera system may calculate a target camera baseline based on a first value and a second value, and dynamically adjust an inter-camera capture distance to match the target camera baseline. The first value may indicate the common field of view and the second value may indicate a distance between the camera system and the object.

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 multiview backlight, multiview display, and method employ arrays of active emitters and a diffuser to provide an effective active emitter from emitted light from each active emitter. The multiview backlight includes an array of active emitters and a diffuser configured to provide effective active emitters having a predetermined size that is between one quarter and two times a size of a light valve of the multiview display. The multiview display includes an array of effective active emitters including active emitters and a diffuser configured to provide output emitted light. The multiview display further includes an array of light valves configured to modulate output emitted light to provide a displayed image. A spacing between effective active emitters is an integer multiple of a spacing between light valves of the multiview display.

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: Described herein are system and methods to improve the image quality of a multiview image. In some embodiments a zero disparity plane image is generated based on a view of a multiview by identifying portions of the multiview image that correspond to the zero disparity plane. The zero disparity plane image and view images of the multiview image may be transmitted to a time-multiplexed display. The time-multiplexed display may operate according to a two-dimensional (2D) mode and a multiview mode. The time-multiplexed display may be configured to display the zero disparity plane image and the view images as a composite image.

Abstract: Time-multiplexed backlighting includes a time-multiplexed light source to provide a light beam having a first non-zero propagation angle during a first time interval and a second non-zero propagation angle during a second time interval. A time-multiplexed backlight includes a light guide configured to guide the light beam and a diffraction grating configured to coupled out a portion of the guided light beam with a different principal angular direction in each of the first time interval and the second time interval. A multiview display includes the time-multiplexed light source and a multibeam backlight to provide coupled-out light beams during each of the first and second time intervals, wherein the principal angular directions of the coupled-out light beams correspond to different view directions of the multiview display.
