Soon, world’s most efficient flexible OLED on plastic!

Published On: Tue, Nov 1st, 2011 | Photonics | By BioNews

Researchers at the University of Toronto have developed organic light-emitting diodes (OLEDs) that enable a flexible form factor and a cheaper alternative to traditional OLED manufacturing.

The world”s most efficient OLEDs provide high-contrast and low-energy displays that are rapidly becoming the dominant technology for advanced electronic screens and are already used in some cell phone and other smaller-scale applications.

Current state-of-the-art OLEDs are produced using heavy-metal doped glass in order to achieve high efficiency and brightness, which makes them expensive to manufacture, heavy, rigid and fragile.

“For years, the biggest excitement behind OLED technologies has been the potential to effectively produce them on flexible plastic,” Zheng-Hong Lu, Professor of materials science and engineering, said.

The research demonstrated the first high-efficiency OLED on plastic and the performance of the device is comparable with the best glass-based OLEDs, while providing the benefits offered by using plastic.

“This discovery, unlocks the full potential of OLEDs, leading the way to energy-efficient, flexible and impact-resistant displays,” he added.

The study has been published online in the latest issue of Nature Photonics.
