Abstract
A multiview backlight and a multiview display employ active emitters configured to provide a plurality of light beams having different principal angular directions corresponding to different view directions of the multiview display. A size of the active emitter is comparable to a size of a view pixel in the multiview display. A distance between active emitters is commensurate with a distance between adjacent multiview pixels of the multiview display. A multiview display further includes an array of light valves configured to modulate the directional light beams to display a multiview image.
