The main objective of the HyperOLED project, a just launched € 4 million project funded by the European Union’s Horizon 2020 research and innovation program, is to develop innovative high-performance OLEDs. This should be done by combining thermally activated delayed fluorescence (TADF) molecular hosts with novel, specifically adapted shielded fluorescence emitters.
The new OLEDs promise to be more cost-efficient to manufacture because they are based on white OLED stacks that are easier to produce compared to current solutions. By reducing the number of layers in the OLED stacks, around 20–4 0% of organic materials can be saved, tact times can be reduced, and less manufacturing equipment will be required. This will lead to considerable savings throughout the whole value chain, including solvents, educts, catalysts in material synthesis, energy saving in purification by sublimation as well as energy saving in OLED production. Furthermore, it is expected to eliminate the need for expensive and rare metals such as iridium and platinum.
Within the project, Merck, as the project coordinator, will be in close collaboration with Microoled, Fraunhofer-IOF, Durham University, and Intelligentsia Consultants. Over a three-year period, the HyperOLED project will develop materials and device architectures for high-performance, hyperfluorescent organic light-emitting diodes (OLEDs) for use in display applications and solid state lighting. The project will directly contribute to the development of thin, organic and large area Electronics (TOLAE) and will help to create reliable TOLAE-enabled devices with increased functionality, improved performance, and longer lifetimes.
