First Efficient Flexible Plastic OLED

The first high-efficiency OLED on plastic was claimed by researchers from the University of Toronto recently, which is deemed as an important development that may lead to more durable and “impact-resistant” displays. The flexible OLEDs were invented by adding 50-100 nm thin layer of tantalum oxide onto plastic, thus to achieve the same refractive index as that of heavy metal-doped glass. The new technology is believed to be producing OLEDs with a low cost, while promoting the efficiency and durability of OLEDs in the meanwhile.
