Application Gallery

Even though 2D OLED models offer very useful insights into the physics of the OLEDs, it is often necessary to run full 3D OLED simulations for results that are realistic and can be used to compare with experiment observations. This section contains a 3D OLED example using the same methodology as the 2D OLED in the previous section. Also discussed are techniques that can be used to reduce the number of simulations required significantly by applying symmetry. These are important topics to consider given that 3D OLED simulations typically require a significant amount of simulation time and memory.

 

This section shows how a multi-layer 3D OLED with PC patterning can be simulated with FDTD using the methodology described in the 2D example The process is very similar to the 2D example from the previous section, and we will omit a lot of the detail here. Therefore, we highly recommend going through the following sections in detail before proceeding on to one of the 3D OLED examples
