3D Master Equation for Exciton dynamics in oleds
We describe a novel simulation approach for excitons in organic light-emitting diodes (OLEDs). We combined a 1D drift-diffusion model with a 3D master equation.
Our approach effectively combines the computational efficiency of a 1D drift-diffusion solver with the physical accuracy of a discrete 3D ME model, where excitonic long-range interactions for energy transfer can be taken into account.
We show that such a hybrid approach can efficiently describe the steady-state and transient behavior of typical OLEDs reported in the literature.
HOW To optimize the CIE coordinates of a blue oled by fine tuning the cavity
In this tutorial, we are demonstrating how to use the optical module of Setfos in order to demonstrate how much the color point of a full OLED can be tuned for a given emitter spectrum. Moreover, we compare the efficiency of the color-optimized device with the one that is tuned for the highest outcoupling/radiance and analyze the consequent trade-off between color purity and efficiency.
The same analysis and optimization can be performed for other types of emitters such as quantum dots or perovskites. Despite the narrow emission spectra of these emitters, the optics of such QLEDs and PeLEDs is equal to the well-established OLEDs.
