Title:
ELECTRODE ARRANGEMENT FOR TESTING ELECTROLUMINESCENT DISPLAY
Document Type and Number:
WIPO Patent Application WO2005034584
Kind Code:
A9
Abstract:
An apparatus for improving testability of electroluminescent displays (ELDs) is provided, incorporating at least two sets of electrodes, one set for connecting rows of pixels, and a second set for connecting columns of pixels, wherein at least one electrode set is interleaved in two subsets. The first subset has electrode extensions of a first length, and the second subset has electrode extensions of a second, shorter, length. A first connector is disposed generally in a direction perpendicular to the electrode extensions of both subsets and in electrical contact with the electrode extensions of the second subset. A second connector is disposed generally in a direction perpendicular to the electrode extensions of the first subset, and in electrical contact with the electrode extensions of only the first subset. A set of insulating patches separate the electrode extensions of the first subset from the first connector. The apparatus of the present invention restricts overvoltage during connection/disconnection of test apparatus.
