the backing defines an opening configured to receive the display module,
the backing does not cover the opening, and
the plurality of segments are selectively movable to a configuration in which a surface of the backing comprises a desired radius of curvature to bend the glass substrate.
2. The apparatus of claim 1 , wherein the backing circumferentially surrounds a periphery of the opening.
3. The apparatus of claim 1 , wherein the plurality of segments comprise a plurality of linkages that are connected to one another along a direction in which the glass substrate is bent.
4. The apparatus of claim 3 , wherein at least some of the plurality of linkages are configured to be positionally fixed relative to one another to maintain curvature of the glass substrate.
5. The apparatus of claim 4 , wherein the plurality of linkages comprise a plurality of linear groups of linkages that are parallel and spaced apart from one another.
6. The apparatus of claim 4 , wherein the at least some of the plurality of linkages are positionally fixed by locking articulating joints connecting the plurality of linkages to one another.
7. The apparatus of claim 4 , wherein the at least some of the plurality of linkages are positionally fixed via an actuator connecting particular ones of the plurality of segments to one another.
8. The apparatus of claim 1 , wherein the glass substrate is bent via movement of the plurality of segments to comprise a curved portion comprising a radius of curvature from 20 mm to 2000 mm.
9. The apparatus of claim 8 , wherein the desired radius of curvature formed by the surface of the backing is within 500 μm of the radius of curvature of the curved portion.
10. The apparatus of claim 1 , wherein the backing with the plurality of segments is separated into distinct portions that are positioned at opposing ends of the glass substrate.
11. An apparatus comprising:
a glass substrate comprising a first major surface and a second major surface;
a bonding medium disposed on the second major surface; and
a backing adhered to the second major surface via the bonding medium, wherein the backing comprises mesh or chain forming a plurality of segments that are connected to one another such that the plurality of segments are selectively movable relative to one another, wherein the backing defines an opening, wherein the backing does not cover the opening;
a display module disposed in the opening; and
an actuator coupled to at least one of the plurality of segments, wherein the actuator is configured to move the plurality of segments relative to one another to facilitate movement of the display module, wherein the plurality of segments are movable to a configuration in which a surface of the backing comprises a desired radius of curvature to bend the glass substrate.
12. The apparatus of claim 11 , wherein the bonding medium is structural tape.
13. The apparatus of claim 11 , wherein, when placed into the configuration, a structural load is placed on the bonding medium, wherein the structural load is more concentrated in a shear force than a static tensile force.
14. The apparatus of claim 11 , wherein the backing circumferentially surrounds a periphery of the opening.
15. The apparatus of claim 11 , wherein the plurality of segments comprise a plurality of linkages that are connected to one another along a direction in which the glass substrate is bent.
16. The apparatus of claim 15 , wherein at least some of the plurality of linkages are configured to be positionally fixed relative to one another to maintain curvature of the glass substrate.
17. The apparatus of claim 15 , wherein the plurality of linkages comprise a plurality of linear groups of linkages that are parallel and spaced apart from one another.
18. The apparatus of claim 11 , wherein the glass substrate is bent via movement of the plurality of segments to comprise a curved portion comprising a radius of curvature from 20 mm to 2000 mm.
19. The apparatus of claim 18 , wherein the desired radius of curvature formed by the surface of the backing is within 500 μm of the radius of curvature of the curved portion.
20. The apparatus of claim 11 , wherein the backing with the plurality of segments is separated into distinct portions that are positioned at opposing ends of the glass substrate.
