A thin-film electroluminescent (TFEL) display panel and method of fabricating a TFEL display are disclosed. The present invention relates to a TFEL display panel shielded by a pair of glass substrates with a protective material disposed therebetween wherein a metal washer is permanently bonded over the substrate oil fill orifices(s) and interfaces the cover glass. This metal washer is prepared in advance by pretinning with a solder to ease reflow after backfill process is complete. This solder provides the seal medium to close the backfill orifice. One of the advantages of using a soldered hole seal according to the present invention is that oil contamination becomes minimized. The backfill hole sealing is accomplished quickly in dry atmosphere without the presence of adhesives of flammable solvents.

Perfluorinated inert liquids are used as the protective fill fluid in thin film electroluminescent (TFEL) flat panel displays according to the present invention. These fluids enhance panel aging and life test characteristics. Novel filling methods are also described.

An arc limiting refractory resistive element is fabricated from aluminum oxide, carbon black and a sintering aid. The fabricating process includes compacting a mixture of the materials, sintering the compact in an inert atmosphere, then oxidizing the outer region of the sintered compact to form a non-conductive sheath around the electrically conductive material.

An arc discharge lamp comprises a ceramic arc tube having an electrode at each end, each electrode being mounted on a support member. A ceramic adapter is sealed to a ceramic cylinder which is sealed to the end of the arc tube. The support member extends through the cylinder into the adapter where it is connected to an externally extending lead-in wire by means of a spiral refractory-metal connector. The connector is flexible enough to withstand the thermal stresses resulting from the normal high operating temperature of the lamp.
