Scattering-Mode Ferroelectric-Photoconductor Image Storage and Display Devices

Abstract

A new type of image storage and display device is described in which the image is stored by means of a longitudinal electro-optic scattering effect in ferroelectric ceramics. The stored image can be viewed directly or projected onto a viewing screen by using transmitted or reflected, polarized or unpolarized, white or monochromatic light. The device has the capability of selective erasure of part or all of the stored image.
