AbstractIn this paper, we propose a technique to enable efficient and rigorous modeling of light emission in planar organic light-emitting diodes (OLEDs) composed of an arbitrary number of layers with different permittivity (including metals of a complex permittivity). The effects of the change of exciton radiative decay rate are explicitly included in the simulation. The numerical implementation of the technique is comprehensively discussed through an illustrative example. By using the proposed method, a bottom emitting OLED with a thick glass substrate is rigorously analyzed. The calculated results show a good agreement with the experimental results. The proposed method is efficient and well suited for optimizing OLEDs with complicated device structures. As a demonstration, we optimize the two-unit tandem top-emitting OLEDs with three types of charge generating layer. The results and design guidelines are given and discussed in detail. © 2007 IEEE.
