Degradation of the luminance and impedance evolution analysis of an OLED under thermal and electrical stress

Abstract : Organic light emitting diodes are one of the most innovative light sources. They do not require semiconductor fabrication techniques like the LED family, they are simple to construct and are used in many original applications. The inconvenient of this product is that it does not have a long lasting useful life with more then 10000 hours. Therefore, this paper will present a parametric method to design an aging model of the OLED based on luminance decay and electrical impedance evolution. Accelerated tests using thermal factor and currentdensity will be applied to large warm white OLED panels. A log-normal model for the luminance decay will be merged withdesign of experiments method to include the stress factors as well as impedance characteristics resulting in an effective degradation model that can estimate the lifetime of the OLED.
