Atomic layer deposition is the best available OLED encapsulation technology


Protection against humidity and moisture is one for the most typical industrial application of ALD. Flexible and organic electronics, such as OLEDs, are extremely sensitive to moisture and oxygen. Beneq's coating equipment and services improve the lifetime value of OLEDs with efficient encapsulation to protect from environmental factors. 

Robust, long lasting OLED products require direct thin film encapsulation with a coating that has a low water vapor transmission rate (WVTR). Conventional thin film barrier deposition techniques are unable to provide low enough WVTR to achieve long product life. The Atomic Layer Deposition (ALD) technology provides unique barrier properties with extremely dense and pinhole-free coatings.
