The lifetime, reliability, and efficiency of organic light emitting diodes (OLED) are critical factors precluding a number of novel devices from entering the market. Yet, these stability issues of OLEDs are poorly understood due to their notorious complexity, since multiple degradation and failure channels are possible at different length- and timescales. Current experimental and theoretical model ...

White Organic Light Emitting Diodes (OLEDs) are potentially highly efficient large area light sources, that can be used for general lighting applications in hitherto unprecedented ways, such as light-emitting flexible foils. In the past years, the luminous efficacy of prototype white OLEDs has shown a very fast, fivefold, increase. In principle, there seems to be no fundamental obstacle towards 10 ...
