Electro-thermal modeling of large-surface OLED

In our project the final purpose is to develop a cost-effective roll-to-roll technology of fabricating large-surface, high-output OLED (organic light emitting diode) devices for intelligent lighting applications. This paper presents the development of the electro-thermal model of OLED devices for circuit-level simulation. The model is based on the measuring of I-V characteristics at ten different temperatures. Our model describes the forward bias and the reverse bias of OLED devices between 5degC and 50degC. The actual initial model ignores the long-term stability problem.
