Abstract

An elementary light-modulating device comprises a light-modulating cell, and other components. The light modulating cell comprises a first transparent electrode, a second electronically conductive electrode, and at least one layer of electrolytic material interposed between the two electrodes and in contact with them in the region of a picture element. The electrolytic material comprises a homogeneous mixture of solid consistency, of at least a water-soluble salt of at least one metal cathodically deposited from an aqueous solution of one of its simple or complex ions, an initially water-soluble film forming polymer resin, and water. The electrolytic material has ionic conductivity and a deformability, and can be formed in layers. The cell further comprises electrical connection zones for conducting electrical current to the electrodes. In addition to the cell, the device comprises electrical current leads in contact with electrical connection zones, electrical connections extending the current leads, and at least one mechanical substrate supporting the device.
