Novaled AG introduced a novel defect tolerant OLED structure at Finetech Japan in Tokyo.

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,” said Gerd Guenther, VP marketing and sales at 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 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.

In time for the Lighting & Finetech event, Novaled launched its web site in Japanese and Korean languages, underlining the importance of the Asian markets.
