Abstract A moving indicator electrochemical display which may be used for a linear, or for a circular display device such as a clockface. A plurality of conductive electrodes are provided on an insulating substrate in a regular pattern and covered with a shallow layer of electrolyte containing ions of a visible electrodepositable material. Electrical circuitry is provided which applies a potential between a pair of adjacent electrodes making one an anode and one a cathode, the potential being sufficient to cause plating of the visible electrodepositable material on the cathode to produce a visible indicator. Switching means cause the potential to shift between successive electrode pairs giving the appearance of a moving indicator device.
A moving indicator electrochemical display system comprising, in combination: A. a nonconductive substrate, B. a plurality of electrically conductive electrodes spaced in a predetermined pattern on said substrate, C. a layer of electrolyte covering said electrodes and containing ions of an electrodepositable material, and D. energizing means for applying an electrical potential between adjacent electrodes to make one an anode and the other a cathode, said potential being sufficient to deposit a visible layer of said electrodepositable material on said cathode, and including switching means for sequentially switching said potential to successive electrode pairs whereby said deposited layer appears to transfer from electrode to electrode in the manner of a moving indicator.
