Abstract: An electronic device may have a display with backlight structures. The backlight structures may produce backlight that passes through the display layers in the display. The backlight structures may include a light guide plate that distributes light across the display layers. A light source such as a light-emitting diode light source may be used to provide light to the light guide plate. In one suitable embodiment, a light guide structure having a bend may be coupled between the light source and the light guide plate and may be used to guide the light from the light source to the light guide plate via total internal reflection. In another suitable embodiment, the light-emitting diodes may be mounted on a flexible printed circuit that is curled into a spring element. The flexible printed circuit may be used to bias the light-emitting diodes against the edge of the light guide plate.

Abstract: An electronic device may have a liquid crystaldisplay with backlight structures. The backlight structures may produce backlight that passes through display layers in the display. The display layers may include color filter elements, a liquid crystal layer, and a thin-film transistor layer. The backlight structures may have a light guide plate with opposing first and second edges. The light guide plate and other display layers may be assembled within support structures such as a metal chassis and a plastic chassis. A first strip of light-emitting diodes may be attached, to the first edge of the light guide plate in a position that is floating with respect to the metal chassis. A second strip of light- emitting diodes may foe attached to the second edge of the light guide plate in a position that is fixed with respect to the metal chassis.

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.

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.
