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.
