Finland's VTT Technical Research Centre developed a new technique to deposit patterned OLED lighting elements on flexible plastic films. This could enable a low-cost process technology to make flexible light emitting structured films - which they see used mostly in advertisement campaigns.
The new room-temperature deposition technology uses standard traditional gravure and screen printing - which means it may be possible to use in regular printing houses. The process makes OLED lighting stripes which are 0.2 mm thick and usespolymer based OLED emitters.
