Abstract
This chapter presents an introduction to organic light-emitting diodes (OLEDs), which are solid-state light sources made of organic semiconductor (OSC) materials. Various functional materials help to facilitate the conversion of injected charges into emitted photons at the maximum possible efficiency, and further are assembled specifically to realize the desired emitted color, whether it be monochrome or broadband emissions for displays or solid-state lighting, respectively. Making use of the chemical variability of OSCs that allows for a tunable luminescence spanning the visible part of the electromagnetic spectrum, OLEDs have successfully transitioned from a lab curiosity to a mature display technology. With further technological advances, these materials also will mature to a large-area, scalable, ultrathin, and freeform solid-state light source for general lighting. This discussion will feature the fundamental working principles of OLEDs, their various design and material realizations (with a special highlight on the various emitter material concepts), and the optical properties of the thin-film architecture, which strongly limit the overall device efficiency. Then it ultimately will give a short summary of current research frontiers in this area.
