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: An electronic device such as a portable computer may have a housing with a rectangular recess in which layers of display structures such as a light guide panel layer and other light guide structures are directly mounted without intervening chassis members. Mating alignment features in the housing and display structures may be used to align the display structures relative to the housing. A display may be formed from glass layers such as a color filter glass layer and a thin-film transistor glass layer. Backlight for the display may be generated by an array of light-emitting diodes. The light guide panel may direct light from the light-emitting diodes through the glass layers. A clamp may be used to hold the light-emitting diodes and light guide structures in place in the recess. An undercut in the housing may also hold the light guide structures in place.

Abstract: A display may include a backlight structure. The backlight structure may include a light guide plate. Holes in the light guide plate may be configured to receive corresponding light-emitting diodes. The holes may separate an edge portion of the light guide plate from a main central portion of the light guide plate. Adhesive may be attached to the lower surface of the edge portion. The adhesive may be attached to a device housing or may be attached to a flex circuit that is attached to the housing with additional adhesive. The light-emitting diodes may be mounted within packages in pairs. The packages may be mounted on the flex circuit. Traces on part of the flex circuit may be covered by part of the light guide plate without any intervening adhesive. A reflective structure may be interposed between the traces and parts of the main portion of the light guide plate.

Abstract: An electronic device housing may contain a display module. The display module may contain layers of material such as a color filter layer and a thin-film transistor layer. These layers of material may be mounted in a display module chassis. A cover glass may cover the display module. The housing may have springs that mate with corresponding holes in the chassis of the display module to hold the display module in place within the housing. The springs may flex about a flex axis that is perpendicular to a planar rear housing surface and the planar layers of the display module. A disassembly tool may be inserted into a gap between the cover glass and housing sidewalls. When the disassembly tool is rotated, a fin on the tool may press against an engagement structure in the spring and may release the spring from the display module.

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: 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: Electronic devices may have housings. A housing may contain a display on its front face and a rear plate such as a plate formed from glass on its rear face. A peripheral housing member may surround the display and rear plate. An antenna may be formed in the peripheral housing member. The rear plate may be formed from laminated layers including a light guide layer. Device hinges may include hinge structures that are integral to the peripheral housing member. A logo may be formed by coating the rear plate with a patterned masking layer. Display structures for the display and the rear plate may be mounted to opposing sides of a shelf portion of the peripheral housing member. The rear plate may be formed from electrochromic glass and may cover photovoltaic cells and touch sensors. Driver boards may be mounted within a clutch barrel perpendicular to the display.

Abstract: An electronic device display may have a color filter layer and a thin film transistor layer. A layer of liquid crystal material may be interposed between the color filter layer and the thin film transistor layer. A layer of polarizer may be laminated onto the surface of the color filter layer. Laser trimming may ensure that the edges of the polarizer are even with the edges of the color filter layer. The thin film transistor layer may have an array of thin film transistors that control pixels of the liquid crystal material in the display. Driver circuitry may be used to control the array. The driver circuitry may be encapsulated in a planarized encapsulant on the thin film transistor layer or may be mounted to the underside of the color filter layer. Conductive structures may connect driver circuitry on the color filter layer to the thin film transistor layer.
