Abstract:
A dual switchable LCD display is disclosed that allows the juxtaposition of a front and rear image. A rear switchable screen is in proximity to the projector system. The rear image is projected on the rear screen at a first time interval. The rear switchable screen has an open state allowing light transmission through the rear screen and a closed translucent state obscuring the rear screen. A front switchable screen overlays the rear switchable screen. The projector system projects the front image on the front screen at a second time interval. The front switchable screen has an open state allowing light transmission through the front screen and a closed translucent state obscuring the front screen. A controller periodically cycles the respective closed and open states between the first and second time intervals to present a juxtaposition of the front image and the rear image to a viewer.
