20130223836 | Electronic Device Assemblies - An electronic device may have a conductive housing. A dielectric structure may be mounted in the conductive housing to form an antenna window. An electrical component such as a camera, light sensor, or other device may press against a conductive foam structure. A printed circuit may have conductive traces that form an antenna ground and antenna resonating element. The printed circuit may be wrapped around a support structure. The electrical component, the conductive foam structure, and the printed circuit wrapped around the support structure may be compressed between a display cover layer and the antenna window. A camera window may be attached to a camera window trim using multiple adhesives. The trim may have a curved exterior surface that matches a curved housing surface. A flexible printed circuit cable may have a folded portion. A band structure may surround the folded portion to form a service loop. | 08-29-2013 |
20130235611 | Light Guide Structures for Display Backlights - An electronic device may have a display with backlight structures. The backlight structures may produce backlight that passes through the display layers in the display. The backlight structures may include a light guide plate that distributes light across the display layers. A light source such as a light-emitting diode light source may be used to provide light to the light guide plate. The light source may overlap an edge portion of the light guide plate. A light guide structure having a bend may be coupled between the light source and the light guide plate. The light guide structure may be used to guide the light from the light source to the light guide plate via total internal reflection. A light guide structure may be provided with light leakage promotion structures to evenly distribute light from a centralized light source along the edge of a light guide plate. | 09-12-2013 |
20130242600 | Backlight Structures and Backlight Assemblies for Electronic Device Displays - An electronic device may have a liquid crystal display with backlight structures. The backlight structures may produce backlight that passes through the display layers in the display. The display layers may include a layer of liquid crystal material interposed between a color filter layer and a thin-film transistor layer. The backlight structures may include a light guide plate. A plurality of light-emitting diodes mounted on a flexible printed circuit may be coupled to an edge of the light guide plate. The flexible printed circuit may be curled into a spring element to bias the light-emitting diodes against the edge of the light guide plate. A plurality of gaps may be formed in the flexible printed circuit and may be used to separate and mechanically decouple adjacent light-emitting diodes. Individual light-emitting diodes may independently register to the light guide plate to maximize optical efficiency in the display. | 09-19-2013 |
20130260081 | LAMINATED ROLL OF SEALED GRAPHITE POUCHES AND METHODS FOR MAKING THE SAME - Laminated rolls of sealed graphite pouches and methods for making the same are provided. The laminated roll can include a first substrate having a length and a plurality of sealed pouches disposed on the substrate at predetermined intervals along its length. Each sealed pouch can include a graphite sheet having first and second sides, the first side affixed to the substrate, and a second substrate affixed to at least the second side of the graphite sheet and to a portion of the substrate to fully seal the graphite sheet within an enclosed space. In one embodiment, the roll of sealed graphite sheet pouches can be fixed to a roll of another substrate in a roll-to-roll fashion and the combined rolls can be cut into discrete portions for use in a particular application. For example, the roll of the other substrate can be a roll of enhanced spectral reflector (ESR). | 10-03-2013 |
20130328792 | Electronic Device with Wrapped Display - An electronic device may have a hollow display cover structure. The hollow display cover structure may be formed from a structure having an inner surface. The structure may be an elongated member having a longitudinal axis. A material such as sapphire, other crystalline materials, or other transparent materials may be used in forming the hollow display cover structure. A flexible display layer such as an organic light-emitting diode display layer or other flexible display structure may be wrapped around the longitudinal axis to cover the interior surface of the hollow display cover structure. The electronic device may have a touch sensor, accelerometer, gyroscope, and other sensors for gathering input such as user input. The electronic device may use one or more sensors to gather information on rotational motion of the device and can display content on the flexible display layer accordingly. | 12-12-2013 |
20130342970 | LOW-FORCE DUST SEAL - An electronic device may have polarizer layers, color filter layers, thin-film-transistor layers, and other display layers. A display layer may be separated from structures such as a display cover layer formed from clear glass or plastic and a touch sensor layer mounted on an inner surface of the display cover layer by an air gap. Cavities within an electronic device housing may serve as a source of dust and other contaminants. The air gap may be sealed against dust intrusion from a cavity within an electronic device using a dust sealing structure. The dust sealing structure may have a rectangular ring shape that runs around a rectangular peripheral portion of a display layer. The dust sealing structure may be formed from a tape-based structure, an elastomeric structure, a compressible foam structure, or a cured liquid structure. | 12-26-2013 |
20140092560 | FORCE AND HEAT SPREADING PCB FOR LCD PROTECTION AND INTERCONNECTION - The described embodiment relates generally to the manufacture of display assemblies. More particularly the use of alternative back plates for a display assembly is discussed. By using a printed circuit board (PCB) in lieu of a metal backer heat can be evenly spread across the backer by applying a layer of copper configured to normalize a spread of heat across the printed circuit board. The configuration of the copper layer can be configured based on a tested or simulated heat map that accounts for proximate heat producing elements. The PCB can also advantageously act as an interconnection layer between other electrical components disposed within the electronic device. | 04-03-2014 |
