Electroluminescent device including a dielectric substrate having a plurality of closely-spaced, thin wire conductors passing therethrough

Claim 1

AN ELECTROLUMINESCENT DEVICE COMPRISING IN COMBINATION: (A) A LIGHT-TRANSMISSIVE ELECTRICALLY-CONDUCTIVE ELECTRODE LAYER; (B) AN ELECTROLUMINESCENT DIELECTRIC-PHOSPHOR LAYER UNDERLYING SAID ELECTRICALLY-CONDUCTIVE ELECTRODE LAYER; (C) A DIELECTRIC SUBSTRATE UNDERLYING SAID DIELECTRICPHOSPHER LAYER, SAID DIELECTRIC SUBSTRATE CONSISTING OF A DIELECTRIC MATERIAL FILLED WITH A PLURALITY OF DISCRETE CLOSELY-SPACED THIN WIRE CONDUCTORS RIGIDLY SEALED IN SAID DIELECTRIC MATERIAL SUCH THAT WHEN AN ELECTRIC CURRENT IS APPLIED TO ONE SAID OF SAID SUBSTRATE SAID CURRENT WILL BE CONDUCTED THROUGH SAID SUBSTRATE TO THE OPPOSITE SIDE THEREOF; AND ((D) CONDUCTIVE MEANS, UNDERLYING SAID DIELECTRIC SUBSTRATE AND IN INTIMATE CONTACT THEREWITH, FOR DEFINING A PREDETERMINED SELECTIVE LOCUS OF CONTACT BETWEEN SAID CONDUCTIVE MEANS AND SAID DIELECTRIC SUBSTRATE;
