Process for fabricating an electroluminescent display device
Abstract
Abstract AN ELECTROLUMINESCENT DISPLAY DEVICE INCLUDES A SUBSTRATE OF CERAMIC MATERIAL HAVING A PLANAR SURFACE, A PLURALITY OF SPACED ELECTRICAL CONDUCTORS EMBEDDED THEREIN INCLUDING SPACED ELECTRODE SEGMENTS AFFIXED TO THE PLANAR SURFACE AND ELECTRICALLY CONNECTED TO AT LEAST ONE OF THE CONDUCTORS EXTENDING IN A DIRECTION NORMAL TO THE PLANAR SURFACE, A LAYER OF DIELECTRIC MATERIAL AFFIXED TO THE PLANAR SURFACE AND ELECTRODE SEGMENTS A LAYER OF PHOSPHORS AFFIXED TO THE DIELECTRIC LAYER, AND A TRANSPARENT CONDUCTIVE LAYER AFFIXED TO THE PHOSPHOR LAYER. IN ONE DISPLAY DEVICE FABRICATION PROCESS, A PLURALITY OF SPACED ELECTRICAL CONNECTORS AND AT LEAST ONE SURFACE OF THE CERAMIC SUBSTRATE MATERIAL ARE PLACED IN CONTACTING RELATIONSHIP, CONFINED WITHIN A MOLD, FIRED TO EMBED THE ELECTRICAL CONDUCTORS IN THE CERAMIC SUBSTRATE MATERIAL AND FORM A SUBSTANTIALLY PLANAR SURFACE OF CERAMIC SUBSTRATE MATERIAL. THEN, THE DISPLAY STRUCTURE INCLUDING A PLURALITY OF SPACED ELECTRODE SEGMENTS FORMING A DISPLAY CONFIGURATION, A LAYER OF DIELECTRIC MATERIAL, A LAYER OF PHOSPHORS, AND A LAYER OF TRANSPARENT ELECTRICALLY CONDUCTIVE MATERIAL IS AFFIXED TO THE PLANAR SURFACE OF THE CERAMIC SUBSTRATE MATERIAL.
