ABSTRACT:
An organic electroluminescent (EL) display panel is disclosed which has a protective cover sealed thereon with a radiation-cured perimeter seal. The organic EL display panel is formed on a radiation-transmissive substrate, and includes at least one metallized leader which is in electrical contact with at least one anode electrode or with at least one cathode electrode. The metallized leader has a patterned seal zone which defines radiation-transmissive apertures. A perimeter seal band is formed over the substrate and extends through the patterned seal zone of the metallized leader. A protective cover has a perimeter seal flange which mates with the perimeter seal band. A bead of a radiation-curable resin is in contact with the seal flange and with the display panel at the perimeter seal band. A source of curing radiation is directed to the bead of radiation-curable resin through the substrate and through the patterned seal zone for curing the bead so as to seal the protective cover on the organic EL display panel with an electrically insulative radiation-cured perimeter seal.
