Scientists Create Quantum-Dot Hybrid Light-emitting Devices

Organic light-emitting diodes (OLEDs), fabricated with layers of organic polymers, are flexible and use less power and less expensive materials than liquid crystal displays. However, OLEDs are expensive to produce-- because the polymers react easily with oxygen and water, they have to be created in high-vacuum chambers--and they need extra protective packaging layers to make sure that once they're integrated into display devices, they don't degrade when exposed to air or moisture.
