    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.

    Abstract: An electronic device may include display layers such as liquid crystal display layers and a backlight unit that provides illumination for the display layers. The backlight unit may include light-emitting diodes that emit light into the edge of a light guide film. To minimize the inactive area of the display, the light-emitting diodes may be tightly spaced to approximate a line light source instead of point light sources. Color and/or luminance compensation layers may be incorporated at various locations within the backlight structures to ensure that the backlight provided to the display layers is homogenous. A thin-film transistor layer of the display may be coupled to a printed circuit board by a flexible printed circuit. The flexible printed circuit may have additional solder mask layers to improve robustness, may include encapsulation, and may have traces with a varying pitch.

    Abstract: A privacy film may have a light-blocking layer that is interposed between first and second transparent substrates. The light-blocking layer may have a plurality of opaque portions and a plurality of transparent portions. The opaque portions may be shaped to ensure light from the display is directed only to the primary viewer of the display. Each opaque portion of the light-blocking layer may extend along a respective longitudinal axis between the first and second transparent substrates. Privacy films used to cover curved displays may have opaque portions that extend along longitudinal axes that have different angles relative to the transparent substrates. Opaque portions in the edge of the privacy film may have longitudinal axes that are at non-perpendicular angles with respect to the transparent substrates. A privacy film for a curved display may also include a light-redirecting layer such as a prism layer or a liquid crystal layer.
