ABSTRACT:
An information display device utilizing the phenomenon of electrophoresis. It comprises two transparent electrodes parallel to one another and assembled in order to constitute a sealed cell filled with a colored fluid, and a thin porous diaphragm scattering the light in a color differing from that of the fluid, the diaphragm being arranged in the vessel parallel to the electrodes. The diaphragm displaces by electrophoresis, from one electrode to the other, under the action of potential differences applied to the electrodes.
