Abstract: A method of fabricating electroluminescent display apparatus by forming a lead-frame from a laminate comprising two metal layers and an intervening insulating layer, is disclosed. The lead-frame comprises an array of laminate strip members, the tip of each of which may be cut back to expose the inside face of one metal layer. A light emitting semiconductor device then is mounted and electrically connected either to the inner or end face of the projecting metal layer. The other contact of the device is connected, typically by a wire lead or a metal beam lead, to the other metal layer of the laminate strip. Each semiconductor device and adjoining portion of the conductive mounting is encapsulated in a molded transparent plastic member, and supporting portions of the lead-frame then are severed to make each encapsulated diode available for individual assembly. Portions of the outer surface of the molded transparent member may be faceted and metal coated for improved light reflection and visual impact.
