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 f...
