A method for manufacturing a bent substrate, which forms a bent part in at least a part of a substrate, in which the substrate includes a second region and a first region, the method for manufacturing including: supporting the first region of the substrate on a substrate support surface of a support member including a mold surface having a same curved surface shape as that of the bent part and the substrate support surface that supports the first region, in a state of facing the second region of the substrate to the mold surface; heating the second region of the substrate to soften the second region of the substrate by the heating; placing the second region along the mold surface of the support member by an own weight of the second region; and transferring the curved surface shape of the mold surface to the second region by an external force.

Embodiments of an article comprising a cold-formed glass substrate in a curved shape, a plurality of separate mechanical retainers, and a frame are disclosed. The cold-formed glass substrate has a first major surface, and a second major surface opposing the first major surface. In one more embodiments, the plurality of separate mechanical retainers are attached to the second major surface of the cold-formed glass substrate. The mechanical retainers may be attached to the frame to define a position for each of the plurality of mechanical retainers, such that the mechanical retainers define the curved shape. Embodiments of processes to form such articles are also provided.

Methods for compensating for warp typically exhibited by glass-based articles having non-uniform thicknesses as a result of ion exchange strengthening are provided. The methods include producing a molding surface of a mold based on a measurement of warp obtained by a specified ion exchange strengthening of a glass-based substrate of non-uniform thickness, such that the molding surface offsets the warp. Glass-based substrates resulting from the mold can then be exposed to the specified ion exchange strengthening and form glass-based articles that are substantially free of warp.
