Corning Large Cover Gorilla® Glass Touch Screen Glass

Corning® Gorilla® Glass is a damage-resistant cover glass that is elegant, lightweight, and durable enough to resist many real-world events that commonly cause glass failure. The composition of Corning Gorilla Glass allows for a deep layer of high compressive stress (created through an ion-exchange process). This compression acts as a sort of “armor,” making the glass exceptionally tough and damage resistant. Additionally, Corning Gorilla Glass is formed using the same proprietary fusion process as all of Corning’s high-technology display substrates. This extraordinarily precise, highly automated process produces glass with exceptionally clean, smooth, flat surfaces and outstanding optical quality.

Large Cover Gorilla® Glass is sized to serve as cover glass for displays including interactive white boards, digital signage and other large-size public displays.
