Novaled AG, leading technology and material provider for a new generation of lighting and display products, will introduce a novel defect tolerant OLED structure at Finetech Japan in Tokyo from 15th to 17th April 2009.
Novaled’s Defect Tolerant OLEDs maintain the appearance of a homogeneously lighted-up surface even in the case of electrical shorts, thanks to the use of its proprietary electrode design. One OLED element consists of two comb-shaped interlocked electrodes, which give a uniform light emission. If a short in one of the stripes appears, the resistance of the stripe will limit the current flow and prevent a further rise of current and temperature, which would otherwise destroy the OLED.
“OLED devices based on the new Novaled structure are well suited for large area lighting or other lighting applications which require a long maintenance cycle”, says Gerd Guenther, VP Marketing and Sales of Novaled AG. ”We are looking forward to presenting an OLED-wall demonstrator at the Novaled booth illustrating the concept of the Novaled defect tolerant structure. The topic will be also discussed in the talk of Mr. Philipp Wellmann of Novaled at Lighting Japan.” Further demonstrators like the Victory OLED Lamp with Novaled PIN OLED® inside will be exhibited to introduce possible lighting applications.
