Abstract
PURPOSE: Side rection free, reproducible, long durable image device consists of a cell containing between electrodes a material comprising a medium of electrolytically coloring and decoloring agent, electrolyte and innert solvent and an additive of crown ethers.
CONSTITUTION: A coloring and decoloring medium essentially consists of an electrolytically coloring and decoloring material such as 1,1'-dibutyl-4,4'-bipyridinium- dibromide, an electrolyte such as KBr and an innert solvent such as CHCl3. To this medium, a crown ether or similar material is added in an amount such that it will become a concentration 10-5 to 1 mole/l. As crown ether, for example, dibenzo- 18-crown-ether can be used. A cell 3 containing electrodes 1 and 2 is filled with the above mixture 5 to form an image indicator. An indicator driving step comprises, external DC 4 application for writing, DC turn off for memory, and reverse voltage application for erasing.
