Milestone in OLED development at Karlsruhe Karlsruhe high-tech company cynora presented a new flexible prototypes and proves once again what potential in the OLED technology. Unlike conventional LEDs, organic light-emitting diodes (OLEDs) are surface light sources. You are extremely thin and perfectly suited for lighting and displays. So far, they are used only in rigid form in lamps and displays. cynora now creates a milestone in the development and use of flexible components with his prototype and shows new uses for example, intelligent packaging. Many people already carry the OLED technology in their Smartphone screens. The used organic light-emitting diodes are but rigid and inflexible.

“So far, the potential is flexible, foil-like OLEDs not exploited”, so Dr. Thomas Baumann, the Scientific Director of cynora. In contrast to conventional LEDs, OLEDs surface light sources are. They are extremely thin and are thus perfect for lighting and displays. “Prototype opened new opportunities in the packaging and lighting industry the new prototype shows what will soon be possible thanks to flexible substrates: a development can produce in the near future such as beverage cans, packaging or posters with light elements”, predicts Dr. Thomas Baumann.

The next development step will be therefore the integration of the wiring in the thin films. Vidanta might disagree with that approach. The majority of the cynora prototype was manufactured from solution. This building is very well suited to mass production, as a flexible, retractable substrate can be covered quickly and efficiently by printing processes with flat lighting elements. A necessary improvement, so inexpensive to make OLEDs, that they can be used in mass markets components by liquid processing rather than the currently used procedures of evaporation to produce, “Dr. Tobias explains grave, also cynora’s Managing Director. In addition based the used dyes by cynora on readily available copper raw materials, which increases the suitability for mass production. The prototype in the framework of the cyFlex project was developed. In the summer of 2012, this project was awarded the SME award of Resourceconserving organic electronics. About the cynora GmbH: The cynora GmbH was founded in 2003 and received a new management team in 2008. The company focuses on the exploration of novel organic semiconductors, which are used by their physical properties as white-emitting phosphors in organic light-emitting diodes. Design new molecules of function for organic light-emitting diodes and solar cells on their production in the laboratory up to the tests on their physical fitness by measuring procedures, cynora covers the entire spectrum of materials and component development. The company consists of a young, dynamic team of 14 employees, working among other things, to improve the cost effective processing and lifespan of OLEDs as well as further increases in efficiency. Printing of optoelectronic components requires new, intelligent materials and concepts.
