Claim 1
Independent Claim
96 words
A PROCESS FOR FORMING AN ELECTROLUMINESCENT CELL HAVING A GLASS SUBSTRATE COMPRISING THE STEPS OF APPLYING AN ELECTROCONDUCTIVE COATING TO ONE SIDE OF SAID SUBSTRATE, APPLYING TO SAID ELECTROCONDUCTIVE COATING A LAYER OF A MIXTURE OF PHOSPHOR AND A DIELECTRIC BINDER MATERIAL SELECTED FROM THE GROUP CONSISTING OF GLASS AND CERAMIC, PREHEATING THE UNIT SO FORMED TO A POINT BELOW THE FIRING TEMPERATURE OF SAID BINDER MATERIAL AND, APPLYING SUFFICIENT ADDITIONAL LOCAL HEAT TO SAID LAYER BY DISSIPATING ELECTRICAL ENERGY WITHIN SAID ELECTROCONDUCTIVE COATING TO RAISE THE TEMPERATURE OF SAID LAYER TO THE FIRING TEMPERATURE THEREOF.
