They have used advanced ion assisted deposition to deposit a high-density, pinholefree thin silicon oxynitride (SiON) film on the OLED surface. The process can be completed at room temperature, which keeps the organic material intact.

OLEDs are promising for the next generation of displays and solid state lighting because they use less power and can be more efficiently manufactured than current technology. However, the intrusion of moisture into the displays can damage or destroy the organic material.

"OLEDs have better colour and flexibility and the capability of larger displays, but companies still need an inexpensive encapsulation method that can be used to mass produce organic electronics that don't allow moisture in," said Wusheng Tong, a senior research scientist at the Georgia Tech Research Institute (GTRI).

Manufacturers now seal displays in an inert atmosphere or in a vacuum environment.
