Abstract:
A portable computer may include battery indicator light structures. Battery status information in the portable computer may be presented to a user using an array of light-emitting diodes or other light emitters. Light-emitting diodes may be mounted on a printed circuit board. A stiffener may provide the printed circuit board with rigidity. The printed circuit board may include a connector that allows the board to be connected to a main logic board. A switch on the printed circuit board may be actuated by a power button on the portable computer. An opaque member with an array of holes may be used to reduce light bleed between adjacent light-emitting diodes. Diffusing plastic may be mounted within the array of holes. Bumps in the diffusing plastic may mate with corresponding holes on a portable computer housing.
Abstract:
An electronic device may include a device housing having a topside and an underside. The electronic device may also include a mounting frame movable above the topside of the device housing and a finger biometric sensor carried by the mounting frame. A flexure member may be coupled to the underside of the device housing and configured to upwardly bias the mounting frame relative to the device housing. A pushbutton switch may be operatively coupled between the finger biometric sensor and the topside of the device housing.
Abstract:
Disclosed herein is a stack-up for an input device. The stack-up may include a flexible substrate having a switch and a light source. The switch has at least two contacts that are bridged in response to actuation of a dome that is positioned above the switch. The flexible substrate includes a signal trace for detecting the actuation of the dome and a power trace for providing power to the light source.
Abstract:
An electronic device housing may have upper and lower portions that are attached with a hinge. At least one portion of the housing may have a rear planar surface and peripheral sidewalls having edges. A display module may be mounted in the housing. The display module may have glass layers such as a color filter glass layer and a thin-film transistor substrate. The color filter glass layer may serve as the outermost glass layer in the display module. The edges of the display module may be aligned with the edges of the peripheral housing sidewalls to create the appearance of a borderless display for the electronic device. The display module may be provided with an opening that allows a camera or other electronic components to receive light. Traces may be provided on the underside of the thin-film transistor substrate to serve as signal paths for the electrical components.
Abstract:
A display may include a color filter layer, a liquid crystal layer, and a thin-film transistor layer. A camera window may be formed in the display to accommodate a camera. The camera window may be formed by creating a notch in the thin-film transistor layer that extends inwardly from the edge of the thin-film transistor layer. The notch may be formed by scribing the thin-film transistor layer around the notch location and breaking away a portion of the thin-film transistor layer. A camera window may also be formed by grinding a hole in the display. The hole may penetrate partway into the thin-film transistor layer, may penetrate through the transistor layer but not into the color filter layer, or may pass through the thin-film transistor layer and partly into the color filter layer.
Abstract:
Embodiments related to an electronic device having an adaptive input row. The adaptive input row may be positioned within an opening of a device and include a cover for receiving a touch and a display that is configured to present an adaptable set of indicia. The adaptive input row may also include one or more sensors for detecting the location of a touch and/or the magnitude of a force of the touch. The adaptive input row may be positioned adjacent or proximate to a keyboard of the electronic device.
Abstract:
Described is an illumination structure for a key of a keyboard. The illumination structure is used to uniformly illuminate the key and any glyphs that are present on the key. The illumination structure includes a light guide having various features that increase total internal reflection and also illuminate the glyphs of the key.

The single membrane sheet may substantially cover the PCB. The keyboard assembly may also include a group of dome switches coupled directly to the single membrane sheet. Another keyboard assembly may include a group of conductive pads and a group of membrane pads. Each of the group of membrane pads may be adhered directly to a corresponding one of the group of conductive pads. The keyboard assembly may also include a group of dome switches coupled directly to the membrane pads. Each of the group of dome switches may be coupled directly to a corresponding one of the group of membrane pads.
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:
An electronic device may have a housing. Electrical components such as a display and other circuitry may be mounted in the housing. The housing may have portions that move with respect to each other such as a lid that rotates relative to a base. A flexible printed circuit may have metal lines that couple components in one portion of the housing to components in another portion of the housing. As the housing portions move with respect to each other, the flexible printed circuit bends. Reliability may be enhanced for the flexible printed circuit by providing the metal layer that forms the metal lines with upper and lower coating layers. The coating layers may be formed from metal with a higher Young's modulus than a metal core in the metal layer. A slot may be formed along the length of the flexible printed circuit to help increase the minimum bend radius exhibited by the flexible printed circuit. Upper and lower metal shield layers may be provided above and below the metal traces.
