Abstract

See full text

A photodisplay device in which an optically addressed image can be viewed indefinitely, erased and readdressed with a new image is disclosed. Optically responsive reversible photochiral materials are incorporated into a bistable cholesteric liquid crystal in an electrooptic display cell. A high resolution image exposed on the cell is fixed by a low voltage pulse to unpatterned electrodes and can be, at a later time, erased with a high voltage pulse.
