Model for birefringence in OLEDs

Since many years, OLEDs are known for producing the highest quality displays. OLED displays are still steadily improving with more and more prototypes of flexible displays. A next hurdle is to bring these prototypes to the mass market. OLEDs consist of a stack of organic semiconductor layers that have to be carefully designed to display perfect colours in all circumstances.

The OLED industry is constantly inventing and testing new organic semiconductor materials. Many of these materials have birefingent optical properties. In past projects PlanOpSim's team has developed a thin film modelling method for light emission from these materials. This dipole emission model for birefringent materials and micro-cavities places no restrictions on the extra-ordinary optical axis of the organic material.
This method was developed as a research project within the Liquid Crystals and Photonics group of Ghent University.
