1. In a thin film electroluminescent device including a plurality of layers including at least a transparent electrode layer, a circuit layer, and at least two layers including an electroluminescent layer and a dielectric layer, said at least two layers disposed between said circuit layer and said transparent electrode layer so as to emit light upon the application of an electric field, the improvement comprising:

  • (a) said plurality of layers supported by a support layer;

    (b) said circuit layer including a plurality of electrically conductive first traces;

    (c) an elongate flexible cable including a plurality of electrically conductive second traces supported thereon, said cable being supported by said support layer;

    (d) a plurality of electrical conductors each having a first end and a second end;

    (e) said first end of each of said conductors bonded directly to and electrically interconnected with a respective one of said first traces;

    (f) said second end of each of said conductors bonded directly to and electrically interconnected with a respective one of said second traces supported by said elongate cable; and

    (g) whereby electrical signals transmitted from respective ones of said second traces to said first traces are used to control said electric field.
