Fast field solver for the simulation of large-area OLEDs

Lighting purpose organic light-emitting devices need special engineering because of the high electrical and thermal requirements of the operation. Our electro-thermal field simulation software is better to satisfy these special demands than the widely used commercial tools. This article surveys the special simulation needs of lighting purpose OLEDs, presents the electro-thermal extension of the FDM-based SUNRED thermal field simulator and the significant algorithmic changes for speed up the program and make it more flexible. The simulation of an existing OLED closes the paper.
