Abstract

A picture display device comprising a solution of a material which is reversibly reducible and oxidizable by means of an electric current. The electrodes constitute a cross-bar system. The device is divided into a number of non-communicating compartments which are filled with the solution. Each compartment comprises an electrode, which electrodes form a first set. Of a second set of electrodes, each electrode is in contact with the liquid in all the compartments.
