Extremely resistant, dirt-repellent, anti-reflective coating for professional public displays
Advanced Optics has expanded its coating expertise in the area of specialty glass and introduced one of the first permanently anti-reflective and oleophobic (DARO) coating to the market for use on SCHOTT’s proven glass CONTURAN®. This is one of the first coating that allows for anti-reflective cover glasses for professional touch displays that are protected against fingerprints and other soiling. The multifunctional DARO coating is particularly well suited for use in interactive kiosk systems in public places, casino game consoles, for equipping devices that are used in marine and medical technology or for other technical displays.
Today, anti-reflective coatings offer the best way to increase the contrast of displays in bright environments. Nevertheless, when used on touch screens, when they are touched fingerprints are left behind and this makes for an unattractive appearance. By combining its coating technologies, SCHOTT now offers a permanent anti-reflective coating that strengthens touch screens made of glass. There are currently very few other products available on the market for manufacturers that feature coatings that are capable of resisting the burden of being touched many times and the chemical stresses fingerprints cause without attacking the surface or making it difficult to clean.
“It is important to us to offer a solution that meets or exceeds the increasing demands of product designers, yet enhances user friendliness,” explains Stefan Lasch, Vice President Strategic Business Field Processed Glass at SCHOTT Advanced Optics. SCHOTT has introduced this coating on the basis of its anti-reflective glass CONTURAN® that many customers all over the world already use for their displays. With its high-performance multifunctional DARO coating on CONTURAN® glass, the company is extending the areas of application for anti-reflective products all the way to the high-end area of professional touch displays. SCHOTT is currently introducing this product to potential customers in Europe, Asia, and North America.
SCHOTT uses the so-called sol-gel coating technology for its CONTURAN® DARO glass which provides the foundation for applying an oleophobic nanolayer in a chemically strong manner and therefore offers extreme long-term resistance. This can be seen in the mechanical resistance tests in which the DARO coating has stood up to more than 450,000 cycles, for example. “This equates to a lifespan of more than 25 years, even if the coating was to be cleaned 20 times a day,” Lasch explains. “By performing long-term stress tests, we want to demonstrate the high quality of this material to our customers and show them the great benefits that our new DARO coating offers, especially in professional display applications,” he adds.
