Vitex Systems Barix is a coating composed of alternating layers of polymer and ceramic thin films that can be deposited on a plastic substrate or directly on an OLED display. Mechanically it is much stronger than glass it replaced as shown by this hammer test.

The technology breakthrough that enables this to be used as the packaging material for flat panel displays is the creation of a barrier layer 10,000 times better than anything currently produced.

With this technology the OLEDs can be realized only 50 micrometers thin.
