Abstract
A transparent structure may have layers with curved cross-sectional profiles. The transparent structure may have inner and outer layers with curved portions formed by bending the layers. A display may be applied to one or more of the inner and outer layers. To reduce the strain applied to the display while being bent into a desired curvature, a carrier film may be used during bending operations. The carrier film may be modified with a patch or openings distribute the strain evenly across the display. Additionally or alternatively, a convex mold may be used to further decrease the strain on the display while being formed into the desired curvature.
