Abstract:
The described embodiments relate generally to computing devices including liquid crystal displays (LCDs) and more particularly to methods for attaching a backlight assembly to a cover glass layer while minimizing an amount of stress transferred through the cover glass layer to the LCD module. A continuous and compliant foam adhesive can be used to bond the cover glass layer to the backlight assembly. The compliant bond can absorb and distribute local stress concentrations caused by structural loads, mismatched surfaces and differing thermal expansion rates between various structures and cover glass layer. This can reduce stress concentrations in the cover glass layer that can lead to stress induced birefringence in the LCD cell. In another embodiment, a series of rigid plates can be bonded to the cover glass layer and attached to the backlight assembly. Point loads applied from the backlight assembly can be distributed over a larger area due to the resilience of the rigid plates.
Abstract:
An electronic device may have a liquid crystal display with backlight structures. The backlight structures may produce backlight that passes through an array of display pixels. The display pixels may include electrode structures and thin-film transistor structures for controlling electric fields in a layer of liquid crystal material. The liquid crystal material may be formed between an outer display layer and an inner display layer. The inner display layer may be interposed between the backlight structures and the liquid crystal material. Thin-film transistor structures, electrodes, and conductive interconnection lines may be deposited in a layer on the inner surface of the outer display layer. A layer of color filter elements may be used to provide the display with color pixels. The color filter elements may be formed on top of the thin-film transistor layer or on a separate color filter array substrate such as the inner display layer.
Abstract:
Head-mounted devices can be formed as a modular system that provides a variety of different components and functions to achieve the results that are desired by a user. The modular configurations allow a user to easily customize a head-mounted device with one or more arm modules to provide features that integrate with other operations of the frame module of the head-mounted device. The arm modules can be easily exchanged with each other to provide different components and functions at different times. Accordingly, a frame module of a head-mounted device need not include permanent components that provide every function that will later be desired by the user. Instead, the head-mounted device can have expanded and customizable capabilities by the use of one or more arm modules.
Abstract:
An illumination structure for a key of a keyboard is used to uniformly illuminate the key and any glyphs that are present on the key. The illumination structure includes a light guide (310) having reflection features (325) positioned at various locations around the light guide that increase total internal reflection, illumination features (315) or light extraction features that are operative to illuminate the glyphs of the key, and light-directing features (330) to direct light emitted from the light emitting element (335) down one of more paths of the light guide (310).
Abstract:
The present application describes various embodiments of systems and methods for providing internal components for portable computing devices having a thin profile. More particularly, the present application describes internal components configured to fit within a relatively thin outer enclosure.
Abstract:
An electronic device may have an elongated sensing strip (20). Control circuitry (16) may use the sensing strip to gather air gesture input from the fingers or other body part of a user. The electronic device may have a housing. The housing may have portions such as upper and lower portions that rotate relative to each other about an axis. A hinge may be used to couple the upper and lower portions together. The sensing strip may extend parallel to the axis and may be located on the lower portion between keys on the lower portion and the axis or on the upper portion between the edge of a display in the upper portion and the axis. The sensing strip may have a one-dimensional array of sensor elements such as capacitive sensor elements, optical sensor elements, ultrasonic sensor elements, or radio-frequency sensor elements.

The electronic device further comprising an input device (1090b) positioned between the first glass sheet (1050a) and the second glass sheet (1050b) and configured to detect an input through the first glass sheet.
Abstract:
Cable assemblies for providing electrical communication between hinged sections of an electronic device are described. The cable assemblies can include a cover that covers one or more cables that run through a hinge region of the electronic device. The cable and cover can be drawn over a mandrel of the hinge region. The cover and the portions of the mandrel can be visible to a user at the hinge region of the electronic device. The cover can be sufficiently rigid to guide a path of the cable and protect the cable from bending beyond a prescribed angle during rotation of the electronic device at the hinge region. The cover can also be sufficiently rigid to prevent ceasing or folding of the cover and the cable during rotation of the electronic device at the hinge region. The cable assemblies can also include a hinged cover that can be pivoted to close a gap between two hinged sections of the electronic device.
