Abstract: Optimizing light out-coupling in organic light-emitting diodes (OLEDs) is at the heart of the development and commercialization of OLEDs for general lighting and display applications as it impacts directly the achievable luminous emission (lm/m2), luminous efficacy (lm/W), and even the lifetime. The improvement of light out-coupling requires having simulation tools at hand to efficiently simulate such OLEDs that include light out-coupling enhancement structures. In this chapter we will first describe the main concepts employed today to improve light out-coupling without employing scattering, and then we will introduce how light scattering-based out-coupling tricks can help to maximize the emitted luminance of the device. On this occasion, we will detail a modeling workflow that allows to accurately simulate OLEDs including scattering structures. In this part, we will make use of simulations in order to optimize the device efficiency. From the simulations it becomes evident that the OLED thin film stack properties and the light scattering structures of the substrate both influence the overall performance and thus have to be jointly optimized.
