Abstract
A multiple-viewer auto-stereoscopic display apparatus includes a display unit, an eye-tracking unit, a light transmission control unit, a light separation unit, and a synchronization control unit. The display unit is configured to display a view sequence of a plurality of view images of a 3D image in multiple viewing zones to one or more viewers. The light transmission control unit is configured to control light transmission to a particular viewing zone. The light separation unit is configured to separate the plurality of view images for the viewers to perceive 3D display. Further, the synchronization control unit is configured to synchronize refreshing of the display unit and the light transmission control unit, wherein a refreshing rate of the display unit equals to a refreshing rate of the light transmission control unit, and to dynamically adjust the view sequence based on the position information of the one or more viewers.
