Corning Willow® Flexible Display Glass
Categories:	Ceramic; Glass; Optical
Material Notes:	At roughly the same thickness as a sheet of copy paper, Alkali-free Borosilicate Willow® Glass provides the inherent benefits of glass in a mechanically bendable form-factor, enabling cost-efficient device processing. Willow Glass can be used in displays to make thinner and lighter portable devices such as smart phones and tablets, without sacrificing device performance or reliability. It is also used for laminate applications like kitchen backsplashes and other vertical surfaces. Information provided by Corning Incorporated.
