Abstract
A multi-zone backlight and multi-zone multiview display with multiple zones selectively provide broad-angle emitted light corresponding to a two-dimensional (2D) image and directional emitted light corresponding to a multiview image to each zone of the multiple zones. The multi-zone backlight includes broad-angle backlight to provide the broad-angle emitted light and a multiview backlight to provide the directional emitted light. Each of the broad-angle backlight and the multiview backlight is divided into a first zone and a second zone that may be independently activated to provide the broad-angle emitted light and multiview emitted light, respectively. The multi-zone multiview display includes the broad-angle backlight and the multiview backlight and further includes an array of light valves configured to modulate the broad-angle emitted light as a two-dimensional image and the directional emitted light as a multiview image on a zone-by-zone basis.
