Abstract
A multiview backlight includes a first array active emitters configured to provide a first plurality of directional light beams and a second array of active emitters configured to provide a second plurality of directional light beams. The second array of active emitters is interleaved between active emitters of the first array of active emitters. Further, directional light beams of each of the first and second directional light beam pluralities have directions corresponding to view directions of a multiview display. A multiview display further includes an array of light valves configured to modulate the directional light beams to display a multiview image. An image resolution of the multiview image is configured to be dynamically selectable according to operational mode.
