Modeling of transform for external quantum efficiency and power efficiency of electroluminescent devices

We report on the rough methods for transforming of external quantum efficiency and power efficiency of organic light-emitting devices (OLEDs). The calculation system based on supposing a perfectly diffuse electroluminescent lambertian surface can be useful for appraising external quantum efficiency and power efficiency in research work. And we set up model of transform for external quantum efficiency and power efficiency of OLEDs and develop computer program to simulate scaling modulus.
