An experimental display structure based on reversible electrodeposition

Films of halide complexes of silver can be electrodeposited onto, or removed from, transparent indium tin oxide contacts in less than 10 msec using a clear liquid mixture of dimethyl sulfoxide (DMSO), silver halide, alkali metal halide, and bromine or iodine. The solutions do not attack the contacts, even at high voltages, as long as adequate silver remains in solution. Variations include a mulled mixture of an opacifier and superionic conductor particles in a variety of organic solvents. The electro‐optic properties of experimental display structures are discussed.
