1. 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 comprising:

  • (a) said plurality of layers supported by a rearwardly disposed support layer directly connected to said circuit layer, where said circuit layer is further distant from said emitted light as said emitted light exits said device than said transparent electrode layer;

    (b) an interface circuit supported by and directly connected to said support layer;

    (c) said support layer rigidly interconnects said circuit layer and said interface circuit such that both said interface circuit and drivers cannot freely move with respect to said circuit layer;

    (d) said interface circuit electrically interconnected with said drivers by a plurality of first electrical lines;

    (e) said drivers electrically interconnected with said plurality of layers by a plurality of third electrical lines separate from said plurality of said first electrical lines so as to enable pixels within said electroluminescent device to be selected;

    (f) an interface controller remotely located from said support layer and electrically interconnected with said interface circuit by at least one second electrical line so as to indicate which pixels within said device to illuminate; and

    (g) the number of first electrical lines is greater than the number of said at least one second electrical line.
