A new type of image storage and display device, called the Fericon, is described in which the image is stored by means of electrically induced surface deformation in ferroelectric ceramics. The preferred method of viewing or projecting the stored image is by reflected light using Schlieren optics. The device has nonvolatile storage and the capability of selective erasure of the stored image.
