Accurate experimental analysis and theoretical representation of OLED emission zone profiles

10 April 2024 • 14:20 - 14:40 CEST | Berlin/Salon 9, Niveau/Level 0

Abstract

A model for characterizing emission zone profiles (EMZ) in organic LEDs is introduced. Considering limits for resolving EMZ features yields a characterization by two parameters only. This enables to compare different EMZ results numerically and to define optimization targets that can be observed experimentally. Exemplary data on current-dependent EMZ shift illustrate the application of the method.

Luis Paniagua Rodríguez graduated in B.Sc. in Physics at the University of Salamanca (Spain) in 2017. On that same year, he started his Master in Photonics at the Friedrich-Schiller-Universität in Jena (Germany), from which he graduated in 2020 with the thesis “Measurement uncertainty and alignment sensitivity during freeform mirror metrology with high-performance computer-generated holograms”. This thesis was written at the Fraunhofer Institute for Applied Optics and Precision Engineering (Fraunhofer IOF) in Jena, where he has been working as research associate. Since 2023, he has been focusing on Organic LED optical characterization and modelling.
