Thin film encapsulation with ALD offers ultimate humidity protection for flexible displays.


OLED (Organic Light Emitting Diode) displays have become common during recent years, but their sensitivity to humidity limits the lifetime of the screens. This is the market where the moisture barrier requirements are the toughest. With the displays now becoming flexible, protective glasses and other thick surfaces that have earlier been used to keep humidity out are no longer a possible means of protection.

Thin film encapsulation with ALD is one of the very few technologies that can create a protective layer that offers the required level of humidity protection and completely follows the contours of the surface, also on flexible displays.
