Abstract:
1. A computer-implemented method for determining an indication of an organic light emitting diode (OLED) device performance based upon a computerized model, the OLED device including an OLED stack having active layers between an encapsulant and an electrode and having an encapsulant-air interface on a side opposite the electrode, the method comprising: receiving input values of parameters relating to an operation or a characterization of the OLED device, the parameters including a structure of the active layers, an index of refraction of the active layers, an orientation and depth of dipoles in the active layers, and an index of refraction of the encapsulant; processing the input values according to a computerized model in order to determine an efficiency of the OLED device and an angular distribution of emission into air at the encapsulant-air interface, the processing comprising: outputting values providing a prediction of the efficiency of the emission from the device into air and an angular distribution of the emission into air based upon results of the processing step.
