Abstract:
A method and apparatus are provided for stamping a piece of ePaper. A grid is positioned within a selected distance to a first side of the piece of ePaper. A grounding pin conductively connects a conductive backing plate located on a second side of the piece of ePaper. The grounding pin completes a voltage path from the grid through the piece of ePaper to the conductive backing plate. A voltage is supplied to the grid and supplying the voltage to the grid changes the appearance of the piece of ePaper to form a stamped image.
