Researchers Develop Cost-Effective, Flexible OLED Displays


Organic Light Emitting Diodes (OLEDs)— high-quality, energy-efficient displays — are already used in some flat screen TVs. But they’re about to become common in everything from electronic paper to adaptive clothing thanks to researchers at the VTT Technical Centre in Finland.

The ROLLED project has found a way to print OLEDs on flexible protective films. The films use a technique called roll-to-roll processing that allows OLEDs to be printed in a fast, cost-effective manner.

In comparison, current OLEDs are produced in a glass substrate.

Since the devices require minimal energy, they can be powered by solar cells, small watch batteries, and even radio waves.

Once the ROLLED research makes OLEDS affordable, they may be embedded in clothing, used in “smart” product packaging, used as paper billboard replacements, and more.
