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.
