Abstract
An electroluminescent panel includes a partial electroluminescent panel base, a layer of electrically isolated conductive areas next to the partial electroluminescent panel base, and an activatable conductive layer next to the layer of electrically isolated conductive areas. The activatable conductive layer is selectively activated to electrically connect selected electrically isolated conductive areas together to define one or more electrically isolated conductive electrode regions.
