Electro-thermal investigation of OLEDs

In our project the final goal is to develop the cost-effective roll-to-roll technology of fabricating large area, high throughput OLED devices for intelligent lighting applications. The main achievements of the first six months of the project are described in this paper. An electro-thermal FDM simulator was developed on the basis of an existing thermal-only simulator. The simulations proved the necessity of building a shunting grid of high conductance at the transparent anode of the OLED device. The model validation technique and a method for the thermal qualification of the targeted device were also elaborated.
