Abstract

In this paper, the inorganic multi-layer encapsulation of thin film was newly adopted to protect the organic layer from moisture and oxygen. Using the electron beam, Sputter, inorganic multi-layer thin-film encapsulation was deposited onto the Ethylene Terephthalate(PET) and their interface properties between inorganic and organic layer were investigated. In this investigation, the SiON SiO2 and parylene layer showed the most suitable properties. Under these conditions, the water vapor transmission rate (WVTR) for PET can be reduced from level of 0.57 g/m2/day (bare substrate) to 1*10-5 g/m2/day after application of a SiON and SiO2 layer. These results indicate that the PET/SiO 2/SiON/Parylene barrier coatings have high potential for flexible organic light-emitting diode(OLED) applications.
