ABSTRACT:
An electrochemical display cell has a layered construction including two electrode layers separated by a dielectric layer. Concentric openings are formed in the dielectric layer and one of the electrode layers exposing a designated portion of the other electrode layer. An electrolyte layer overlaps the one electrode layer and the designated portion of the other electrode layer. When activated, current flow cascades through the openings in the one electrode layer and the dielectric layer to the designated portion of the other electrode layer supporting an electrochemical reaction that erodes the designated portion revealing underlying visual information.
