Abstract
A property-enhanced cover sheet, and methods for forming a property-enhanced cover sheet, for a portable electronic device are disclosed. A property-enhanced cover sheet is formed by thermoforming a glass sheet into a specified contour shape while modifying one or more properties of the glass. Other property-enhanced sheets can be formed by layering two or more glass sheets having different material properties, and then thermoforming the layered sheets into a required contour shape. Property enhancement for a cover sheet includes, hardness, scratch resistance, strength, elasticity, texture and the like.
