Vitex developed a moisture barrier film used for OLED encapsulation called Vacuum Polymer Technology (VPT). The company says that their barrier is equivalent to glass in terms of water or oxygen penetration and can be applied to flexible substrates or over a finished display.
Vitex has licensed its IP to several companies and in December 2008 said that Samsung, UDC, LG and other companies are all using VPT in OLED products and prototypes. In June 2006 we interviewed Vitex's sales & marketing director.
In 2010, Vitex was acquired by Samsung Mobile Display.
