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.

Abstract: Conductive adhesive films can include a binding material having a first set of conductive particles therewithin. The binding material can be electrically non-conductive and can flow between and bond external electronic components during a bonding process. The first set of conductive particles can each have cores formed of a first material, such as polymer, and coatings surrounding the cores, the coatings formed of a second material that is electrically conductive, such as nickel. The binding material can also include a second set of smaller conductive particles formed of a third material that is electrically conductive, such as copper, which can have coatings formed of a fourth material that is electrically conductive, such as silver. The first set of conductive particles can each be sphere shaped, and the second set of conductive particles can each be flake shaped. The conductive particles can form electrical paths between the external electronic components.
