Abstract
An electro- and magneto-optic device which comprises a fluid suspension of anisotropic platelets in a dielectric media, and a means for imposing an electrical or magnetic field on the suspension. Orientation of such platelets in the media is accomplished by imposition of an electrical or magnetic field. The invention may be used to provide an information display or a field controlled shutter in window glass.
