Abstract: An electronic device may have a display, a display cover layer, and an image transport layer formed from a coherent fiber bundle. The coherent fiber bundle may have an input surface that receives an image from the display and a corresponding output surface to which the image is provide through the coherent fiber bundle. The coherent fiber bundle may be placed between the display and the display cover layer and mounted to a housing. The coherent fiber bundle may have fiber cores with bends that help conceal the housing from view and make the display appear borderless. A central portion of the coherent fiber bundle may be formed from different materials and/or structures than a surrounding border portion of the layer.

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: An electronic device has sensors. More particularly, the electronic device is a small form factor electronic device such as earbuds, styluses, or electronic pencils, earphones, and so on. In some implementations, one or more touch sensors and one or more force sensors are coupled to a flexible circuit. In various implementations, the touch sensor and the force sensor are part of a single module controlled by a single controller. In a number of implementations, the flexible circuit is laminated to one or more portions of an interior surface of the electronic device.
