First Large-Scale Flexible OLED Film

Mar-04-15 Researchers have developed a flexible OLED film that can be printed using a printing machine and could bring new dynamics to advertising displays.

The technology, developed by a team from the VTT Technical Research Center, would allow OLED elements to move beyond glass surfaces and onto flexible plastics, which in turn enables much larger light surfaces to be created. Currently, the team believes they will be most attractive to advertisers, who can use the large, flexible screens to draw more attention to their ads than standard displays that do not illuminate.

The OLEDs are printed using gravure and screen printing methods, and will emit light for about a year before succumbing to oxygen and moisture. And since OLED light can be used as a transmitter, the films open the door to new ways to use printed light surfaces in Internet of Things applications.
