Numerical Analysis on the Electrical and Optical Properties in Multilayer OLED Device

초록

In this paper, we report our numerical study on the electrical and optical properties in multilayer organic light emitting diode (OLED) device structure. Our finite element method (FEM) model includes the transport behavior of electrons and holes, the generation and decay of excitons, and emission and extinction properties of excitons. We made a focus on the charge balance in host material comprising a phosphorescent OLED (PHOLED). Finally, we investigated the variation of charge density and recombination density, which affect exciton density.
