ABSTRACT:
A spatial light modulator has a modulating region which is capable of operating in two modes in the first clear mode, the region is continuously and substantially uniformly transmissive. In a second or barrier mode, the region can be switched to form parallax barrier comprising slits which are separated by continuous opaque regions. Such A modulator may be used in association with an image liquid crystal display to provide an autostereoscopic 3D display having a 3D mode which may track movement of an observer and a 2D mode in which full resolution of the LCD is used.
