Barrier materials and films, e.g. for encapsulation of OLEDs and OPV, remain a challenge, and further standardization efforts are required to qualify encapsulation. The OE-A Working Group Encapsulation addresses several topics relating to the encapsulation of organic electronics.
The goal of the OE-A Working Group Encapsulation is to gather the experts in the field, identify red brick walls and define goals, in order to trigger the standards development process. Therefore, the group started round-robin tests to clarify permeation testing, qualify sealant materials and barrier-on-foil materials with optical and electrical, as well as calcium-tests. The focus lies on “Lead Applications and Communication in the Value Chain”, “State-of-the-Art and Roadmap”, as well as “Standardization of Encapsulation Metrology”.
OE-A Encapsulation Database
OE-A is hosting an Encapsulation State-of-the-Art Database exclusively for OE-A members to provide them with latest information in the field of encapsulation
The basic functionalities of this database are:
- Information about the activities of the OE-A Working Group Encapsulation
- Sharing of files and documents
- Sharing of News
Interested OE-A members will be granted access by contacting email@example.com or firstname.lastname@example.org.
Experimental comparison of high-performance water vapor permeation measurement methods
A standardized measurement for the transport rate of water vapor has been published by G. Nisato and others. Current topics include, among others, the measurement of side diffusion of water vapor through the barrier layer.
