ABSTRACT:
A liquid crystal moving picture projector (1) includes a liquid crystal imager (2) for creating characteristics of an image, and projection optics (3) for projecting images sequentially created by the imager, the imager including a liquid crystal material (4) capable of temporarily storing information at respective areas thereof to create image characteristics capable of being projected sequentially by the projection optics. The temporary storage may be a function of charge storage directly on liquid crystal material or by structural storage characteristics relying on bulk effect of smectic liquid crystal. A method of projecting plural images in sequence includes creating an image or characteristics of an image in a liquid crystal material, storing such image in such liquid crystal material, directing light at such liquid crystal material, projecting such image as a function of light transmitted through or scattered by such liquid crystal material, and creating a further image in such liquid crystal material for subsequent projection.
