OLED

OLED, also known as Organic Emiting Diode, is a semiconductor light source, similar to a light-emitting diode (LED). In contrast with a LED, which is an inorganic bright light source, an OLED uses a series of thin, light emitting films. As a result, OLEDs produce brighter light and while using less energy.

OLEDs are used to create digital displays in electrical devices such as television screens, computer monitors, laptops and portable-game-consoles, among others.

    Working within the framework of Lyteus, Holst Centre and Fraunhofer FEP step into the spotlight with the creation of the world’s longest single-device OLED. At a stunning 15 meters in length it opens the door to ‘endless OLEDs’ that manufacturers and designers can then easily tailor to their own needs. Lyteus brings together leaders in OLED technology from across Europe to create a pilot production line and product development services for OLED products. Working together, Holst Centre and Fraunhofer FEP successfully demonstrated the possibility for continuous production of OLEDs of any length. This both reduces the cost of production and enables “cut-to-fit” lighting for applications such as transportation, architecture and interior design.

    Only twice as thick as a strand of hair, or around 100 µm: that’s how thin the transparent, scratchproof and malleable ceramic layers of the future that are meant to protect portable electronics are. Since March 2017, the methods and process chains for producing this material have been in development at the Fraunhofer Institute for Laser Technology ILT as part of a three-year research project called CeGlaFlex. Mobile electronics, regardless of whether it is a cellular phone, tablet or blood pressure monitor, rely on the quality of their touch-screen displays. In keeping with the trend of individually shaped smart devices, they should be not only scratchproof, unbreakable and chemically stable, but also easy to mold.

  • Molecular libraries for organic light-emitting diodes

    A new screening process means that promising OLED lighting materials can be identified more efficiently. AG Matthias Wagner

    Organic light-emitting diodes (OLEDs) are promising candidates for flexible flat displays. By means of a screening process developed by chemists at Goethe University Frankfurt, it is now possible to identify more quickly lead structures with superior luminescence and charge-transport properties. The rising demand for increasingly sophisticated smartphones, tablets and home cinemas is a growing challenge for display technology. At present, organic materials are the most effective way to master this challenge. In particular molecules from the class of materials known as polycyclic aromatic hydrocarbons (PAHs) can be used to produce large and mechanically flexible flat screens. They unite brilliant colours with high resolution and are at the same time low in energy consumption.
