Abstract
A construction for an electroluminescent display device comprises an electroluminescent element stack having an outer edge and including a light emitting electroluminescent panel, an electronic circuit board, and a connector electrically coupling the electronic circuit board to the electroluminescent panel. A frame member of generally U-shaped cross-section fits over and compresses the electroluminescent element stack along the outer edge. Additionally, a method of constructing an electroluminescent display device comprises the steps of forming an electroluminescent element stack having a light emitting panel, an electronic circuit board and a connector coupling the electronic circuit board to the electroluminescent panel. The electroluminescent element stack is formed to have an outer edge. A frame member is formed to have generally U-shaped cross-section and resilient arms. The frame member is fitted onto the outer edge of the electroluminescent element stack so as to compress the electroluminescent element stack together. The frame member may be formed by extrusion. The connector may be an elastomeric connector.
