OLEDs – State of the art report: Up-to-date and characterization

This report is prepared within the project “OLED Academy - prospects for energy saving and design” (ELFORSK: 349-032; DTU PROJECT NO. 71012.). The project is carried out by the department of photonics engineering at the technical university of Denmark (DTU Fotonik) in collaboration with Danish Lighting Centre (DCL), an association of lighting professionals in Denmark, and a group of Danish lighting designers. This report summarize the state of the art of the technology of organic
light emitting diodes (OLEDs). The first part of the report introduces the current technology of OLEDs, different types of panels and their performance. The second part presents a characterization of light quality and efficacy of panels available on the market 2015-2018. Since the number of producers are limited and has decreased lately, the characterization covering seven panels from three producers is considered adequate for describing the market. The report is targeted against people within the lighting industry, whether as designers, production, marketing or research, but aims to be available for anyone with an interest in the subject. Within the project, a final report has also been produced, describing the design competition and its results.
