Patent ID: 7497755

Claim:
An Electroluminescent Display (ELD) and testing apparatus combination comprising: a substrate, a matrix of pixels, arranged in rows and columns, formed on said substrate to define an active area of said ELD, at least first and second sets of electrode extensions, each electrode extension set comprising a plurality of electrode extensions, each electrode extension of said first set extending from a respective row of pixels of said matrix, and each electrode extension of said second set extending from a respective column of pixels of said matrix, wherein one of said first and second electrode extension sets comprises a first subset of electrode extensions of a first length and a second subset of electrode extensions of a second length, wherein the second length is shorter than the first length and wherein the electrode extensions of said first and second subsets are interleaved, a first connector, generally extending in a direction perpendicular to the electrode extensions of said first and second subsets, and in electrical contact with the electrode extensions of said second subset, a second connector, generally extending in a direction perpendicular to the electrode extensions of said first subset, and in electrical contact with the electrode extensions of only said first subset, and a set of insulating patches electrically separating said electrode extensions of said first subset from said first connector, wherein all said connectors are located beyond the periphery of said active area to define a scribing region along said electrode extensions between said periphery and said first connector thereby to enable said connectors and a portion of said electrode extensions to be removed from said ELD by scribing off said periphery or by scribing a gap in the electrode extensions to electrically isolate that portion of the electrode extensions connected to the rows and columns of said matrix from that portion of the electrode extensions in electrical contact with the connectors.
