Abstract: Scattering particles have been shown to increase the efficiency of OLED devices by a number of authors. For real life applications of OLED efficiency is only one figure of merit, accurate modelling of the colour appearance and stability under various angles is equally important. We present a complete simulation model and experimental validation for OLEDs with scattering particle extraction layers. Including modeling of the colour coordinates. The model is valid for both external and internal outcoupling layers as well as combinations of both.. Additionally we present a joint optimization of the OLED structure and the scattering layer (concentration, size, host & particle material) The modelling was performed using Setfos 4.1.
