Abstract:
An electronic device may have a display. Inactive portions of the display such as peripheral portions of the display may be masked using an opaque masking layer. An opening may be provided in the opaque masking layer to allow light to pass. For example, a logo may be viewed through an opening in the opaque masking layer and a camera may receive light through an opening in the opaque masking layer. The display may include upper and lower polarizers, a color filter layer, and a thin- film transistor layer. The opaque masking layer may be formed on the upper polarizer, may be interposed between the upper polarizer and the color filter layer, or may be interposed between the color filter layer and the thin- film transistor layer. The upper polarizer may have unpolarized windows for cameras, logos, or other internal structures.
Abstract:
Electronic devices may be provided with backlight structures that provide backlight illumination for a display. The backlight structures include a light source such as an array of light-emitting diodes that launches light into an edge of a light guide plate. The light guide plate distributes the light laterally across display layers in the display. One or more optical films such as brightness enhancement films and diffuser layers are interposed between the display layers and the light guide plate. The light guide plate includes light guide plate alignment features that mate with corresponding optical film alignment features in the optical films. The light guide plate alignment features may be protrusions that extend into openings such as notches or holes in the optical films. The light guide plate may have a protruding portion that extends around a periphery of the light guide plate and surrounds a perimeter of the optical films.
Abstract:
An electronic device may have a housing with a lid that rotates relative to a base. A display in the lid may have a thin-film transistor layer. Display driver circuitry may be mounted to the thin-film transistor layer. A display timing controller integrated circuit may be mounted in the base. A rigid flex printed circuit may have a rigid portion in the base to which the display timing controller integrated circuit is mounted and may have a rigid portion in the lid. A flexible printed circuit portion of the rigid flex printed circuit may be used to couple the rigid printed circuit portion in the lid to the thin-film transistor layer. A flexible printed circuit portion of the rigid flex printed circuit that extends between the lid and the base may be formed from a double-shield-layer single-signal-line-layer flexible printed circuit.
Abstract:
An electronic device may be provided with a display. The electronic device may include a housing. A display trim may be formed from injection molded plastic that is molded directly onto the housing. The molded plastic trim may form a rectangular ring around the periphery of the housing. The housing may have angled or curved interior surfaces that are covered by the molded plastic trim. Computer-controlled positioners may be used to center the housing within an injection molding tool. Independently controlled positioners may also be used in capturing the housing between the lower die and the upper die in the injection molding tool. The injection molding tool may inject thermoplastic elastomer material into a channel in the upper die to form the plastic display trim.

Abstract:
An electronic device 10 may be provided with an organic light- emitting diode display 14 with minimized border regions IA. The border regions IA may be minimized by providing the display with bent edge portions 56 having neutral plane adjustment features 58 that facilitate bending of the bent edge portions while minimizing damage to the bent edge portions. The neutral plane adjustment features may include a modified backfilm layer 52 of the display in which portions of the backfilm layer are removed in a bend region. A display device may include a substrate, a display panel on the substrate having display pixels, and peripheral circuitry proximate the display panel and configured to drive the display pixels. A portion of the periphery of the substrate may be bent substantially orthogonal to the display panel to reduce an apparent surface area of the display device. The bent portion may include an electrode for communication with the peripheral circuitry.
Abstract:
A camera may be mounted under a display in an electronic device. The display may include a polarizer layer, a color filter layer, and a thin-film-transistor layer. A layer of material such as a glass insert may be attached to an edge of the display. Openings may be formed in the layers of the display and the insert to accommodate the camera. A sleeve structure may be mounted within an opening. The camera may include lens structures formed from a stack of lens elements. One or more layers of the display may be interposed within the lens structures. The glass insert may be mounted within a notch in the color filter layer and thin-film transistor layer or along a straight edge of the color filter layer and thin-film transistor layer. The edge of the color filter layer may be recessed with respect to form a mounting shelf for the insert.
Abstract:
An electronic device such as a laptop computer or other device may have a housing. A display may be coupled to the housing. The display may have a pixel array configured to display an image. Backlight illumination for the pixel array may be provide by a backlight unit. The backlight unit may have a light guide layer. A light source may provide light to an edge of the light guide layer. The light guide layer may scatter the light outwardly to serve as the backlight illumination for the pixel array. The backlight unit may have optical films interposed between the light guide layer and the pixel array. The optical films may include flexible polymer layers such as diffuser layers and prism films. The optical films may each have a bent alignment portion that bends back on itself while wrapping around an edge of the light guide layer.
Abstract:
Embodiments are directed to an electronic device having an illuminated body that defines a virtual or dynamic trackpad. The electronic device includes a translucent layer defining a keyboard region and a dynamic input region along an external surface. A keyboard may be positioned within the keyboard region and including a key surface and a switch element (e.g., to detect a keypress). A light control layer positioned below the translucent layer and within the dynamic input region may have a group of illuminable features. The electronic device may also include a group of light-emitting elements positioned below the optical diffuser. One or more of the light control layer or the group of light-emitting elements may be configured to illuminate the dynamic input region to display a visible boundary of an active input area. At least one of a size or a position of the visible boundary may be dynamically variable.
