Novaled is showing their Defect Tolerant white OLEDs. Those displays 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.
