Abstract
An autostereoscopic display includes a steerable display backlight, having a light output arrangement for providing lines of light output and a first lenticular lens array, with each lens focused near a corresponding line of light output. A display panel is illuminated by the backlight and a second lenticular array generates at least two views to different viewing directions. Head and/or eye tracking is used for tracking at least two viewers. Views are provided to the two eyes of a tracked viewer at the same time, and views are provided to the two eyes of different tracked viewers time-sequentially.
