A scale-photo-electro-thermal model of Organic Light-Emitting Diodes (OLEDs) for design lighting systems

摘要

A model for Organic Light-Emitting Diodes (OLEDs) based on datasheet information and experimental tests to approach the interaction among scale-photo-electro-thermal (SPET) domains is presented in this paper. The model has been verified for two different OLEDs, with favourable agreement among theoretical and experimental results. The results show the influence of scale factor on heat transfer mechanism and the temperature effect on electrical and photometrical performance. This model is useful for predicting OLED behaviour and for simulating OLED drivers during the design of the lighting system.
