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.

Abstract: A two dimensional touch sensor panel can be thermoformed or curved by another process to a three-dimensional touch sensor panel, and the three-dimensional touch sensor panel can be laminated to a three-dimension surface having a highly curved or spherical shape. In some examples, thermoforming a two-dimensional touch sensor panel into a three-dimensional touch sensor panel can result in strain of the touch electrodes, and can result in non-uniform three-dimensional touch electrodes (distortion of the two-dimensional touch electrode pattern). The strain can be a function of the curved touch-sensitive surface and/or process related mechanical strain from thermoforming. In some examples, a three-dimensional touch sensor panel can be formed with uniform area touch electrodes using a two-dimensional touch sensor panel pattern with non-uniform area touch electrodes in accordance with the strain pattern expected for a given curved surface and thermoforming technique.
