Abstract:
An organic electroluminescent (EL) display panel including at least one light-emitting region and having a protective cover sealed thereon with a radiation-cured perimeter seal, comprising:(a) a radiation-transmissive electrically insulative substrate having formed thereon, in order, at least one radiation-transmissive anode electrode, an organic EL-medium, and at least one cathode electrode, at least the anode electrode being electrically addressable to receive an electrical potential with respect to the cathode electrode so as to effect light emission from the light-emitting region;(b) at least one optically opaque metallized leader, the leader being in electrical contact with the at least one cathode electrode or with the at least one anode electrode, the metallized leader having a patterned seal zone which defines radiation-transmissive apertures which permit radiation to pass therethrough from the substrate so as cure a resin overlying opaque portions of the seal zone;(c) a perimeter seal band provided over the substrate and extending through the patterned seal zone of the metallized leader;(d) a protective cover having a perimeter seal flange adapted to mate with the perimeter seal band over the substrate; and(e) a bead of an electrically insulative radiation-cured resin in contact with the perimeter seal flange of the cover and with the perimeter seal band over the substrate so as to seal the protective cover on the organic EL display panel with an electrically insulative radiation-cured perimeter seal.
