Glass-clear appearance, scratch-proof surfaces – Openair® plasma treatment for plastic and LCD displays

Displays are coated with a special coating during the last stage of the manufacturing process. This coating improves scratch resistance and enhances the quality of surfaces such as those made of PC (polycarbonates) and PMMA (polymethyl methacrylate).

To ensure that this coating adheres, surfaces must be pretreated. Openair® plasma offers the perfect inline process to accomplish that, replacing elaborate processing that uses low-pressure plasma treatment.

This means a significant simplification of the process chain in the manufacture of displays and a substantial reduction in scrap rates.

Since 2007, the Openair® plasma system has been in continuous use at GfO AG. Each year, hundreds of thousands of display windows made of PC or PMMA are treated with atmospheric plasma before the hard coat is applied.
