Osram developed the worlds most efficient flexible OLED lighting panel with an efficiency of 32 lm/w.
The substrate for the OLED is a steel foil with a thickness of approximately 100 micrometers – thus meaning it is as thin as a sheet of paper. Because this steel foil is opaque, the light cannot shine through it as would be the case with rigid OLED on glass, but has to shine to the upper side. This so-called “Top-Emitter” technology makes it more complicated to design high-quality white light.

Research samples such as the record OLED represent an important step on the road to providing flexible OLED in widespread commercial application. “With this research success, OSRAM further underscores its leading position in the field of OLED,” said Ulrich Eisele, head of OLED at OSRAM. The head of technology, Thomas Dobbertin, supplemented this comment by stating that “with this sample, we are able to demonstrate that flexible OLED can already be significantly more efficient than halogen lamps. This was only made possible thanks to our ability to transfer our strong competence in the field of vacuum processing of organic functional materials and space saving thin film encapsulation onto flexible OLED.”
