Researchers create first efficient flexible plastic OLED

Scientists at the University of Toronto claim to have discovered a method to manufacture flexible OLEDs that could lead the way to more durable and “impact-resistant” displays. Zhibin Wang and Michael Helander used in their invention a 50-100 nm thin layer of tantalum oxide on plastic to achieve a refractive index that was previously only delivered by heavy metal-doped glass. The researchers believe that the technology can reduce the cost of production of OLEDs and bring the vision of flexible OLEDs to the mainstream market.
