Communication: If organic light-emitting diodes (OLEDs) are to be used for displays, e.g., in seven-segment displays such as that in the Figure, either the metal cathode or the anode (usually indium tin oxide, ITO) must be subdivided. A new subdivision technique based on localized destruction of the ITO layer of commercial substrates by scorching with a tungsten needle is described and experimental and theoretical results are presented.
