  • Patent number: 7698842
    Abstract: A plate, e.g., a license plate for motor vehicles, includes a base body which is made of an electrically conductive material, or has an electrically conductive layer applied either directly or via a further layer. Thus, the electrically conductive base body or its electrically conductive coating forms a first electrode of a flat capacitor. A layer having an electroluminescent pigmentation is applied on the base body or the electrically conductive layer. The electroluminescent coating may be applied by various methods, e.g., spray painting, brushing, special screen-printing methods, etc. To create the electrical field, it may be necessary to apply to the electroluminescent layer an electrically conductive layer for forming the second electrode.
