Abstract: A portable electronic device can include a housing defining an aperture and a display positioned in the aperture. The portable electronic device can include a number of components that can provide desired functionalities and levels of performance. For example, the device can include one or more couplers that interconnect various portions of the housing together. Additionally or alternatively, the portable electronic device can include one or more millimeter-wave antennas. Additionally, or alternatively, the electronic device can include one or more grounding elements or layers that reliably and electrically ground the display to the housing.

Abstract: A display may have a pixel array such as a liquid crystal pixel array. The pixel array may be illuminated with backlight illumination from a direct-lit backlight unit. The backlight unit may include an array of light-emitting diodes on a printed circuit board. The backlight unit may include first, second, and third light spreading layers formed over the array of light-emitting diodes. A color conversion layer may be formed over the first, second, and third light spreading layers. First and second brightness enhancement films may be formed over the color conversion layer.

Abstract: A display may have a pixel array such as a liquid crystal pixel array. The pixel array may be illuminated with backlight illumination from a backlight unit. The backlight unit may include a printed circuit board, a plurality of light-emitting diodes mounted on the printed circuit board, at least one light spreading layer formed over the printed circuit board that spreads light received from the plurality of light-emitting diodes, a partially reflective layer formed over the at least one light spreading layer, a color conversion layer formed over the partially reflective layer, a collimating layer formed over the color conversion layer, a brightness enhancement film formed over the collimating layer, and a diffuser formed over the brightness enhancement film. The at least one light spreading layer may include two light spreading layers with elongated protrusions that are rotated relative to each other.

Abstract: An electronic device may have a hinge that allows the device to be flexed about a bend axis. A display may span the bend axis. The device may have a stainless steel and/or carbon fiber reinforced polymer layer with slots. The slots may overlap the bend axis. The slots may have at least one property that varies in a non-linear manner as a function of position on the layer. The device may include an adhesive layer with a cutout that overlaps the slots. An interface that defines the cutout may have a plurality of recesses with varying depths. A flexible printed circuit may be attached to an edge of the display panel. The display cover layer may overlap a bonding region between the flexible printed circuit and the edge of the display panel. A UV-curable gap filler may be interposed between the flexible printed circuit and the display cover layer.
