Abstract

An elementary light-modulation device comprises a light-modulation cell (A) composed of a first transparent electrode and a second electronically conductive electrode. At least one layer of electrolytic material is interposed between the two electrodes and in contact with them in the region of a point image or image segment, said material comprising, in combination, at least one homogeneous mixture, of solid consistency, of at least one water-soluble salt of a metal which can be 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 material is ionically conductive, deformable, and conformable in layers. The device also comprises regions for supplying electric current to the electrodes; (B) current supply elements in contact with said current supply regions; (C) electric connections prolonging the current supply elements; (D) at least one mechanical substrate which supports the device.
