In the world of lighting, the organic light-emitting diode (OLED) is one of the most intriguing and promising new technologies. OLEDs are used in advanced high-contrast displays, and their low energy consumption makes them particularly attractive with the increasing proliferation of electronic devices.

OLEDs are typically manufactured by an expensive process involving glass doped with heavy metals, and they are fragile and rigid as a result. However, researchers from the Department of Materials Science & Engineering at the University of Toronto have recently developed a new plastic-based manufacturing method for OLEDs. The result is a more cost-effective, efficient, and flexible material.

“For years, the biggest excitement behind OLED technologies has been the potential to effectively produce them on flexible plastic,” says Professor Zheng-Hong Lu. “This discovery, unlocks the full potential of OLEDs, leading the way to energy-efficient, flexible and impact-resistant displays.”
