ABSTRACT:
A multi-panel electroluminescent panel assembly is provided in which an area extending over several panels may be uniformly illuminated by light produced by the panels, and over which non-illuminated areas, stripes or the like resulting from electrode contacts are eliminated. Each panel is constructed such that the light produced per unit area is substantially uniform throughout the panel, including that from an area immediately adjacent at least one edge thereof. The panels are assembled in an overlapping arrangement such that non-illuminating areas of one panel are covered by illuminating areas of at least one other panel. The assembly of panels provides a large area source of uniform illumination suitable for back-lighting graphic indicia, and may be desirably included as signboards on the sides of motor vehicles such as transport trucks, buses, etc.
