Abstract:
An electronic device may have structures that are coupled together using conductive adhesive such as anisotropic conductive film and other adhesives. The structures that are coupled together may include a touch sensor structure formed from electrodes on the inner surface of a display cover layer, a display module having display layers such as a thin-film transistor layer, and circuitry mounted on substrates such as printed circuits. Conductive signal path structures may be used in routing signals within the electronic device. The conductive signal path structures may be formed from pins that are embedded within injection molded plastic, from metal traces such as laser-deposited metal traces that are formed on the surface of a plastic member or other dielectric, from metal structures that run within channels in a plastic, printed circuit traces, and other signal path structures.
Abstract:
An electronic device may have a housing, electrical components, and other electronic device structures. A display may be mounted in the housing. The display may have a transparent display cover layer and a display layer such as an organic light-emitting diode display layer that is mounted to the underside of the transparent display cover layer. A flexible printed circuit with metal traces may be mounted under the organic light-emitting diode display layer. The metal traces may form coils for a near-field communications inductive loop antenna. A magnetic shielding layer may be interposed between the housing and the flexible printed circuit. The magnetic shielding layer may include a polymer magnetic shielding layer having magnetic material particles embedded in a polymer matrix. The magnetic shielding layer may also have a polymer-binder-free magnetic shielding layer.
Abstract:
An electronic device may be provided with printed circuits. Electrical components may be interconnected using signal paths formed from metal traces in the printed circuits. The printed circuits may include flexible printed circuits with bent configurations. The flexible printed circuits may be provided with integral bend retention structures. A bend retention structure may be formed from a polymer layer, a solder layer, a stiffener formed from metal or polymer that is attached to flexible printed circuit layers with adhesive, a conformal plastic coating that covers exposed metal traces at a bend, a metal stiffener with screw holes, a shape memory alloy, a portion of a flexible printed circuit dielectric substrate layer with a reduced elongation at yield value, or combinations of these structures. The bend retention structure maintains a bend in a bent flexible printed circuit.
Abstract:
The disclosed embodiments relate to a technique for inductively charging an electronic device. This technique involves winding an audio cable for the electronic device around a charging mechanism multiple times so that one or more conductors in the audio cable form an inductive receiving coil. Next, a magnetic field is created through the charging mechanism to induce a current in the inductive receiving coil. Finally, the induced current in the inductive receiving coil is used to charge a rechargeable battery for the electronic device.
Abstract:
Apparatus, systems and methods for shock mounting glass for an electronic device are disclosed. The glass for the electronic device can provide an outer surface for at least a portion of a housing for the electronic device. In one embodiment, the shock mounting can provide a compliant interface between the glass and the electronic device housing. In another embodiment, the shock mounting can provide a mechanically actuated retractable. For example, an outer glass member for an electronic device housing can be referred to as cover glass, which is often provided at a front surface of the electronic device housing.
Abstract:
Apparatus, systems and methods for characteristics of glass components through use of one or more coatings are disclosed. The coatings are typically thin coatings, such as thin film coatings. The coatings can serve to increase strength of the glass components and/or provide durable user interfacing surfaces. Accordingly, glass articles that have received coatings are able to be not only thin but also sufficiently strong so as to resist damage from impact events. The coated glass articles are well suited for use in consumer products, such as consumer electronic devices (e.g., electronic devices).
Abstract:
Split jack assemblies are constructed with a tubeless pin block. Elimination (or split) of the tube, or more particularly, a tube that is an integrally formed part of the pin block form the pin block allows for the use of a tubeless pin block design that results in a jack assembly having smaller overall dimensions than a conventional jack assembly constructed to accommodate a plug of the same dimensions. The tubeless pin block can be used in conjunction with a tube sleeve or with a curved surface of a housing for an electronic device, or both to provide a plug receptacle of the split jack assembly.
Abstract:
Flexible printed circuit structures may be provided that have regions with different electrical and mechanical properties. A flexible printed circuit substrate may be formed from a sheet of polymer having different regions with different thicknesses. The flexible printed circuit substrate may be bent in a thin region of the substrate. Additional flexible printed circuit substrate portions may be coupled to the flexible printed circuit substrate. The additional portions may have different substrate thicknesses. A groove or other recess may be formed in a flexible printed circuit substrate to promote bending. Openings may also be formed in the substrate to promote bending.
Abstract:
Various embodiments for detecting and rejecting false, unintended rotations of rotary inputs of electronic devices are disclosed herein. In one example, an electronic device is provided with an optical detector that measures the distance between the electronic device and the wearer's forearm or hand, and when the distance is smaller than a threshold distance, the turns of the rotary input are false, unintended turns. In another example, a crown of a rotary input includes a plurality of capacitive sensors that detects the presence of a wearer's finger, which when absent, the turns of the rotary input are false turns. In another example, deflections or positions of a shaft of the rotary input are measured and if the deflections/positions indicate an upward force on the rotary input (which are likely caused by the wearer's forearm or hand), the turns of the rotary input are false turns. Other embodiments are described herein.
