  • Patent number: 8084941
    Abstract: The present invention is related to an OLED display, and one aspect of the OLED display includes a substrate member, an insulating layer formed on the substrate member, a metal wire formed on the insulating layer and having a plurality of joining enhancement holes, a sealant formed on the metal wire, and a sealing member attached on the sealant. In some embodiments, the joining enhancement holes efficiently suppress stripping of the sealant from the metal wire, since the sealant can integrally bond with the interlayer insulating layer through the joining enhancement holes. This feature may compensate for any weak bonding adherence between the sealant and metal wire. In some embodiments, the area of the joining enhancement holes may range from about 5% to about 60% of the entire area of the metal wire.
