sim4tec GmbH, a  spinoff from the Institute for Applied Photophysics (Institut für Angewandte Photophysik) at the Dresden Institute of Technology and a provider of numerical simulation software for organic electronics, will show its OLED simulation software SimOLED, which enables users to model the complete optoelectrical characteristics of OLEDs consisting of up to 40 layers.

SimOLED calculates current density, luminance and efficiency and transient and steady-state values; generates spatially resolved plots of charge carrier profiles, exciton profiles, recombination rates and electric field; and handles the treatment of singlet and triplet excitons, including charge and emitter doping,  model interface dipoles, exciplex states and quenching effects.

SimOLED uses a database in which all input and output is stored and grouped automatically, enabling users to trace results to the input parameters at any time.
