An electrically controlled visualization device comprising an electrochromatic material placed between a first electrode and a second electrode, said electrodes being supported respectively by two plates at least one of which is transparent, and said electrodes being connected to a voltage source adapted to produce a displacement of ions by diffusion which modifies the aspect of the said material, wherein an electric heating current passes through one of said electrodes, the duration of the application of said voltage being selected in such as a manner that said displacement is dependent on said current.
