BENEQ: Ultimate OLED encapsulation with ultrafast spatial ALD

When the consumer electronics industry moves towards flexible solutions, encapsulation of flexible OLED displays against moisture permeation is one of the most difficult challenges. Totally conformal and pinhole-free ALD barrier films are ideal for ensuring a long lifetime for flexible OLEDs. They provide better barriers than traditional thick CVD solutions and much thinner coatings than the complex multi-layer PECVD barrier film alternatives.

But the coating quality of ALD thin films has actually never been the point of concern – the high encapsulation performance is widely accepted. The question in the consumer electronics business has been whether ALD can be productive enough. What has now changed?

The advances in low temperature plasma ALD processing and spatial ALD as a means to increase the equipment productivity have transformed ALD-based barrier coatings from a research topic to a viable encapsulation alternative in mass production. The high capacity of the latest spatial ALD solutions has brought the cost of ownership of ALD to acceptable levels also for consumer electronics applications.
