SCHOTT offers cover glass innovations for next-gen displays

June 8, 2012 — Specialty glass producer SCHOTT announced the market entry of its Xensation cover glass, an alumino-silicate glass offering improved resistance to breakage and scratches for touchscreen display panels. The company also debuted a special anti-glare effect capable of significantly reducing glare on high-resolution displays.

Xensation cover glass launched in late 2011 and underwent an extensive qualification process at all large consumer electronics brands. First models of touch screen devices using Xensation cover glass will appear on the market in Q3 2012, said Lutz Gruebel, head of global sales and marketing activities of the SCHOTT Xensation brand family.

Tests took place at SCHOTT and customer sites using industry-standard cover glass processing parameters. Xensation cover glass consistently reached compressive stress values greater than comparable materials’ results: up to 20% higher bending strength.

Xensation cover glass can be chemically strengthened in less time than competitor glass types, the company reports.

High-resolution displays can become distorted by adverse viewing conditions, such as bright sunlight or high ambient lighting. Xensation cover floated alumino-silicate glass is subjected to a custom-designed etching process developed by glass surface modification specialist Berliner Glas, whereby ions are taken out of the glass surface during etching to make it diffuse. Uniform removal of material is a critical requirement for ensuring the glass surface is perceived as faultless by the human eye and Xensation cover’s unique glass structure, combined with Berliner Glas’ etching technology, offers a uniform, homogenous structure not previously possible with ultra-strong glass types. Xensation Cover AG (Anti-Glare) glass is an ultra-strong glass that can be reproducibly treated and etched in a continuous, industrial-scale production process.
