Abstract
A computer-implemented model for use in predicting the efficiency of light emission from constructions of organic light-emitting diodes (OLEDs). The model, as implemented using computer processing, provides essentially-exact solutions to the behavior of light in the sandwiched layers and the encapsulant of the constructions, and it can predict nearly exactly the overall efficiency of device emission relative to the quantum efficiency of emission, as well as the angular distribution of light emitted by the device. Use of the computer-implemented modeling thus eliminates the need to build and evaluate each and every design as a physical prototype.
