Abstract: A multiview backlight and a multiview display employ multibeam elements configured to provide a plurality of light beams having different principal angular directions corresponding to different view directions of the multiview display. The display includes multiview pixels that include sub-pixels. A size of the multibeam element is comparable to a size of a sub-pixel in a multiview pixel of the multiview 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.

Abstract: Dual-direction collimation and a dual-direction optical collimator provide dual-direction collimated light at a non-zero propagation angle. The dual-direction collimator includes a vertical collimator configured to collimate light in a vertical direction and a horizontal collimator configured to collimate the vertically collimated light in a horizontal direction. The horizontal collimator is located at an output of the vertical collimator. A three-dimensional (3D) display includes the dual-direction collimator, a plate light guide and an array of multibeam diffraction gratings at a surface of the plate light guide to couple out the dual-direction collimated light guided in the plate light guide as a plurality of light beams corresponding to different 3D view of the 3D electronic display.

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.

Abstract: Vehicle monitoring employs three-dimensional (3D) information in a region adjacent to a vehicle to visually highlight objects that are closer to the vehicle than a threshold distance. A vehicle monitoring system includes a 3D scanner to scan the region adjacent to the vehicle and provide a 3D model including a spatial configuration of objects located within the scanned region. The vehicle monitoring system further includes an electronic display to display a portion of the scanned region using the 3D model and to visually highlight an object within the displayed portion that is located less than the threshold distance from the vehicle.
