Abstract
Disclosed is a method of forming a glass article. In the method, a mid-frame is adhered to a glass sheet in a flat configuration. The glass sheet has a first major surface and a second major surface opposite to the first major surface. The mid-frame is adhered to the second major surface of the glass sheet. The glass sheet and mid-frame are bent over a forming surface of a chuck so that the glass sheet is in a curved configuration. The forming surface includes a first radius of curvature of 20 mm or more, and the first major surface of the glass sheet conforms to the forming surface. A frame is attached to the mid-frame, and the frame holds the glass sheet in the curved configuration.
