    Abstract: Abstract of the Disclosure 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 5 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 10 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 15 have unpolarized windows for cameras, logos, or other internal structures.

    Abstract: An electronic device comprising: one or more input structures; a storage structure capable of storing one or more executable routines; a processor capable of receiving inputs from the one or more input structures and of executing the one or more executable routines; and a liquid crystal display (LCD) capable of displaying an output of the processor, wherein the LCD includes: a liquid crystal display panel; and an edge-lit backlight unit 104 configured to output light to the liquid crystal display panel, the backlight unit including: a light guiding plate106; a light source 108 adjacent a lateral edge of the light guiding plate; and a turning film 120 disposed over the light guiding plate, the turning film including a plurality of prisms 118 on a surface of the turning film facing the light guiding plate, wherein the plurality of prisms includes prisms having apex angles between approximately fifty and sixty-five degrees; wherein the light guiding plate is configured to receive light from the light source at the lateral edge such that the received light propagates through the light guiding plate and is redirected by lenses of the light guiding plate to emit light to the turning film, and wherein light emitted from an emission surface of the light guiding plate is distributed within a primary distribution range of thirty-five degrees to eighty-five degrees measured with respect to a normal of an emission surface of the light guide and at a peak incident angle between fifty-seven degrees and sixty-three degrees with respect to the normal from the light guide.
