ABSTRACT:
A visual image display device with improved resolution contains a pair of conductive electrodes in spaced relationship. Adjacent one electrode is a first barrier layer which is typically a resin such as polyamide containing a readily oxidizable and reducible material such as zinc nitrate. Adjacent the other electrode is a thin film of solvent, for example, 1,2-dichloroethane. Positioned between the film of solvent and the first barrier layer is a second barrier layer which is a normally light transmitting recording medium. The second barrier layer is both photoionizable and capable of electrochemically producing a colored species. Typically the second barrier layer is a solid containing a resin such as polyvinyl butyral, an active material such as 1-p-anisyl-3 diethylamino styryl-5-diethylaminophenyl-2-pyrazoline and, in selected embodiments, an activator such as carbon tetrachloride.
