Abstract

Light display structures are provided that are simple and comprise few parts so that they can be economically fabricated from various polymers and quickly assembled. They are especially suited for carrying light-emitting elements (22) and lend themselves for realization in a variety of forms such as elongate display structures and sheet-like display structures. They are based upon a plurality of light-emitting elements (e.g., light-emitting diodes) that are coupled between first and second conductors (24, 25) with the addition of other structures (e.g., spacers (26), wire bonds (142), tabs (166)) that facilitate the energizing of the light-emitting elements.
