Abstract
A method of forming a curved, rigid display article includes providing a first substrate having a first initial geometry and a second substrate having a second initial geometry, wherein the first substrate and the second substrate are bendable at room temperature. The method includes optically bonding the first substrate and the second substrate together with a layer of optical bonding material to form an initial workpiece having a geometry that matches one of the first initial geometry and the second initial geometry. The method also includes shaping the initial workpiece to form a shaped workpiece having a radius of curvature of at least 0.1 mm. The method also includes structurally bonding together the shaped workpiece and a curved frame that is not flexible and has a final radius of curvature of from 0.1 mm to 300 mm with an adhesive to thereby form the curved, rigid display article.
