Claim 1
Independent Claim
137 words
THE METHOD OF MAKING AN ELECTROLUMINESCENT DISPLAY PANEL WHICH COMPRISES FORMING A SELF-SUPPORTING SHEET COMPRISED OF AN ELECTROLUMINESCENT PHOSPHOR DISPERSED IN AN ORGANIC MATRIX MATERIAL, APPLYING TO ONE SIDE OF SAID PHOSPHOR-CONTAINING SHEET A SEGMENTED BACK ELECTRODE LAYER COMPRISING AN ARRAY OF DISCRETE ELECTRODE SECTIONS, APPLYING OVER THE SAID ONE SIDE OF SAID PHOSPHORCONTAINING SHEET AND OVER THE SAID DISCRETE ELECTRODE SECTIONS THEREON A PREFORMED INSULATOR SHEET OF A LOW DIELECTRIC CONSTANT ORGANIC THERMOPLASTIC MATERIAL HAVING APERTURES OVERLYING RESPECTIVE ONES OF SAID ELECTRODE SECTIONS, APPLYING ELECTRICALLY CONDUCTIVE LEADS OVER THE SAID PLASTIC INSULATOR SHEET TO EXTEND FLATWISE THEREACROSS FROM THE EDGE THEREOF INTO ELECTRICAL CONTACT WITH RESPECTIVE ONES OF SAID ELECTRODE SECTIONS THROUGH THE SAID APERTURES IN THE INSULATOR SHEET, AND APPLYING A LIGHT-TRANSMITTING ELECTRICALLY CONDUCTIVE FRONT ELECTRODE LAYER TO THE OTHER SIDE OF SAID PHOSPHOR-CONTAINING SHEET.
