摘要:
Systems, methods, and devices are disclosed for applying concealment of components of an electronic device. In one embodiment, an electronic device may include a component that is disposed behind a window configured to selectively become transparent or opaque, such as a polymer-dispersed liquid crystal (PLDC) window. The component includes an image capture device, a strobe flash, a biometric sensor, a light sensor, a proximity sensor, or a solar panel, or a combination thereof. Additionally, the electronic device includes data processing circuitry configured to determine when an event requesting that the component be exposed occurs. Furthermore, the electronic device includes a window controller that may control the window to become transparent, to expose the component upon the occurrence of the event requesting that the component be exposed.

A portable electronic device is provided that has a hybrid antenna. The hybrid antenna may include a slot antenna structure and an inverted-F antenna structure. The slot antenna portion of the hybrid antenna may be used to provide antenna coverage in a first communications band and the inverted-F antenna portion of the hybrid antenna may be used to provide antenna coverage in a second communications band. The second communications band need not be harmonically related to the first communications band. The electronic device may be formed from two portions. One portion may contain conductive structures that define the shape of the antenna slot. One or more dielectric-filled gaps in the slot may be bridged using conductive structures on another portion of the electronic device. A conductive trim member may be inserted into an antenna slot to trim the resonant frequency of the slot antenna portion of the hybrid antenna.

A method of manufacture for a portable computing device is described. In particular, methods and apparatus for assessing a quality of weld joints used to connect one or more components of the portable computing device are described. The weld joints can include one or more weld points. At a weld check station, using a vector network analyzer, a test signal generated can be passed through the weld joint and a response signal can be measured. The measured characteristics can be used to assess a quality of the weld joint. In one embodiment, the vector network analyzer can be used to generate a number of high frequency test signals that are passed through the weld to perform a time domain reflectometry measurement where the weld joint can be accepted or rejected based upon the measurement.

An electronic device may be provided with a display and a multi-layer printed circuit. Integrated circuits and other components may be mounted to the multi-layer printed circuit. The display and multi-layer printed circuit may share a common layer formed from a flexible substrate. The flexible substrate may have portions that are integrated into the display and portions that are integrated into the multi-layer printed circuit board. The flexible substrate may contain patterned conductive traces that are used to route signals from components in the multi-layer printed circuit to display circuitry such as a display driver integrated circuit. An array of thin-film transistors may be used to control the emission of light from the display and may be formed on portions of the flexible substrate that are integrated into the display. The display may be a flexible display that includes an array of organic light-emitting diodes.

A computer-implemented method is disclosed. The method includes: detecting at least two touches on a touch screen; determining a touch area corresponding to at least two of the touches; determining a location on the touch screen in proximity to, but at least partially outside of the touch areas; and displaying a point of interaction at the determined location on the touch screen.

Electronic devices may have openings that serve as potential pathways for moisture intrusion into interior portions of the devices. An electronic device may be provided with moisture repelling coatings in the vicinity of these openings to help prevent moisture from reaching the interior of the device. The openings may be associated with gaps between adjacent housing structures, openings for buttons, openings for audio and connector ports or other openings in device structures. The moisture repelling coatings may be applied to housing surfaces, button members, structures associated with audio and connector ports, and other device structures.

Electronic devices may be provided that contain wireless communications circuitry. The wireless communications circuitry may include antenna structures that are formed from an internal ground plane and a peripheral conductive housing member. A conductive path may be formed that connects the peripheral conductive housing member and the internal ground plane. The conductive path may include a flex circuit. The flex circuit can include a solder flow barrier to constrain flow of solder. A metal structure may be welded to the peripheral conductive housing member. A solder pad and other traces in the flex circuit may be soldered to the metal structure at one end of the conductive path. At the other end of the conductive path, the flex circuit may be attached to the ground plane using a bracket, screw, and screw boss.
