摘要： An electronic device with a force sensing device is disclosed. The electronic device comprises a user input surface defining an exterior surface of the electronic device, a first capacitive sensing element, and a second capacitive sensing element capacitively coupled to the first capacitive sensing element. The electronic device also comprises a first spacing layer between the first and second capacitive sensing elements, and a second spacing layer between the first and second capacitive sensing elements. The first and second spacing layers have different compositions. The electronic device also comprises sensing circuitry coupled to the first and second capacitive sensing elements configured to determine an amount of applied force on the user input surface. The first spacing layer is configured to collapse if the applied force is below a force threshold, and the second spacing layer is configured to collapse if the applied force is above the force threshold.

摘要： An electronic device may have a display, a display cover layer, and a sheet-packed 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 transported. 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. The coherent fiber bundle has filaments formed from elongated strands of binder in which multiple fiber cores are embedded. Sheets of filaments are stacked and fused together to form the coherent fiber bundle. By aligning and fusing the sheets with respect to each other the filaments are packed with a desired density and uniformity.

摘要： 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.

摘要： Reinforcement components for electrical connections with limited accessibility Shield structures with reduced spacing between adjacent insulation components and systems and methods for making the same are provided. In some embodiments, a reinforcement component may be compressed between two portions of a first electronic component in order to deform the reinforcement component for filling in a void between the reinforcement component and a coupling formed between the first electronic component and a second electronic component. The first electronic component may be a flexible circuit component that may be folded over the reinforcement component prior to the reinforcement component being compressed. This may enable the reinforcement component to be effectively positioned with respect to the first electronic component prior to being deformed for reinforcing one or more couplings made between the first electronic component and the second electronic component.

摘要： A hybrid laser modulation and acid etch process for the creation of a patterned substrate. According to some embodiments, a hole is formed in a glass substrate by first modulating a portion of the substrate in the desired shape. A mask is coated on the glass substrate and is patterned to expose the modulated portion. The glass substrate is then acid etched to remove the modulated portion. Once the modulated portion has been etched, the desired shape may be removed from the glass substrate and the mask may be stripped.

摘要： A display may have a backlight with a row of light-emitting diodes that emit light into an edge surface of a light guide layer. The light guide layer may have opposing planar surfaces. Light-scattering structures such as light-scattering holes that extend between the planar surfaces may be used to scatter rays of light by refraction and/or diffraction and can thereby homogenize light from the light-emitting diodes. The homogenized light may then be extracted from the light guide layer and may serve as backlight illumination for an array of pixels such as an array of liquid crystal display pixels. Light-scattering structures such as grooves, pits, bumps, and other structures for scattering light from the light-emitting diodes may be formed on the edge surface of the light guide layer to enhance light mixing.

摘要： An electronic device may have a housing with a display. A protective display cover layer for the display may have an image transport layer formed from fibers or Anderson localization material. The image transport layer may include light absorbing material. Light absorbing material may be incorporated as an additive into a component of the image transport layer such as the binder layer of a coherent fiber bundle or the cladding of fibers in the image transport layer. The image transport layer may also be formed from fibers with a light absorbing layer formed in addition to a transparent cladding. The image transport layer may be formed from Anderson localization material that has light absorbing material. Fibers for the image transport layer may be extruded with light absorbing portions. A polymer preform having light absorbing material may be drawn to form fibers for the image transport layer.

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.

摘要： A force input sensor includes a load cell to adapt a compressive force applied to the force input sensor into a strain experienced by a strain sensor in the load cell. In particular, the load cell includes two compression plates separated from one another by a gap so as to define a volume between them. A flexible substrate (a “diaphragm”)—includes a strain sensor and is disposed and supported within the volume. One of the two compression plates includes a feature (a “loading feature”) that extends toward a central region of the flexible substrate. As a result of this construction, when the compression plates receive a compressive force, the loading feature induces a bending moment in the flexible substrate, thereby straining the strain sensor.
