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.
Claims10
A multiview display comprising:
- an array of multiview pixels configured to provide a plurality of different views of the multiview display as converging views, a multiview pixel comprising a plurality of light valves configured to modulate a tilted plurality of light beams having different principal angular directions corresponding to view directions of the different views;
- a light guide configured to guide light;
- and
- an array of multibeam elements, each multibeam element of the multibeam element array being configured to couple out a portion of the guided light as the tilted plurality of light beams,
- wherein a tilt of the tilted plurality of light beams is configured to direct a central axis of the tilted plurality toward a center of a view zone of the multiview display to provide converging views, the central axis of the tilted plurality of light beams being configured by the tilt to intersect the view zone center.
