New white top-emitting OLED architecture achieves high efficiency and outstanding color quality
Dec 24th
Researchers from Dresden’s University of Technology (TU Dresden) developed new highly efficient white top-emitting OLED design that feature “outstanding” color quality, and is compatible with flexible OLEDs. In this new design a refractive index matched microlens film was laminated to the top-emitting OLED to form direct optical contact. This enabled the researchers to achieve a CRI of 93, CIE coordinates of (0.472, 0.430) and an emission from 410 to 750 nm that almost spans the complete visible spectrum (380 to 780 nm). The efficiency is up to 30 lm/W (on par with the latest record white OLEDs from Novaled and OSRAM ). The lamination of such an outcoupling structure should be fully roll-to-roll compatible and even allows to be used as an encapsulation film when water and oxygen barriers are added. read more

The Holst centre shows how durable OLEDs are
Sep 22nd
The Holst centre released a couple of videos showing how durable flexible OLEDs are – they can be hit by a hammer or even be cut in half and still continue to work: The OLED being cut video is actually rather old, it was released in 2009 , but they just uploaded it to YouTube again and it’s nice to see. The hammer video seems to be new, although we’ve seen these kinds of videos before – from UDC in 2007 and Samsung in 2009 . read more
