    Abstract: An array of pixels in a display may be illuminated by a backlight having an array of light sources such as light-emitting diodes. The light-emitting diodes may be mounted on a printed circuit. A reflector may be formed on the printed circuit to help reflect light from the light- emitting diodes upwards through the pixels. The reflector may include two white ink layers. Multifunctional layers and other optical films may be incorporated into the backlight. These layers may include diffusers, microlens array layers, thin-film interference filters, phosphor layers, light-collimating layers, and reflective polarizers.

    Abstract: An electronic device may generate content that is to be displayed on a display. The display may have an array of liquid crystal display pixels for displaying image frames of the content. The display may be operated in at least a normal viewing mode, a privacy mode, an outdoor viewing mode, and a power saving mode. The different view modes may exhibit different viewing angles. In one configuration, the display may include a backlight unit (42) that generates a collimated light source and that includes a switchable diffuser film (200) for selectively scattering the collimated light source depending on the current viewing mode of the display. In another configuration, the display may include a backlight unit that generates a scattered light source that includes a switchable microarray structure such as a switchable mirror structure or a tunable microlens array for selectively collimating the scattered light source depending on the current viewing mode.

    Abstract: Displays such as liquid crystal displays may be provided with structures that minimize curtain mura. A display may have upper (22) and lower (24) polarizers. A color filter layer (12) and a thin film transistor layer (14) may be located between the upper and lower polarizers.

    Abstract: An edge-lit backlight unit for a display is provided. In one embodiment, the backlight unit may include a light guide configured to receive light from a source and emit such light in a broad distribution to a turning film disposed over the light guide. The turning film may be configured to redirect light received from the light guide toward a normal of the turning film. In one embodiment, the light guide may be configured such that peak light distribution therefrom occurs at an incident angle of approximately sixty degrees, with broad light distribution substantially occurring over an angular range between incident angles of thirty-five and eighty- five degrees. Additionally, in one embodiment, the turning film may include multiple prisms that receive and redirect the light emitted from the light guide, and that include apex angles of less than or about sixty degrees. Additional edge-lit backlight units and methods are also disclosed.

    Abstract: A pixel array may be illuminated with backlight illumination from a backlight. The backlight may include a two-dimensional array of light-emitting diodes, with each light- emitting diode being placed in a respective cell. Different light-emitting diodes may have unique brightness magnitudes based on the content of the given display frame. Driver integrated circuits may control one or more associated light-emitting diodes to have a desired brightness level. The driver integrated circuits may be formed in an active area of the backlight. The driver integrated circuits may be arranged in groups that are daisy chained together. A digital signal (that includes information such as addressing information) may be propagated through the group of driver integrated circuits. To manage thermal performance of the backlight, the backlight may include a thermally conductive layer and/or a heat sink structure. To increase the efficiency of the backlight, the backlight may include one or more reflective layers.

    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: An electronic device may have a display with a backlight (42). The backlight provides backlight illumination for an array of pixels (24) that is displaying images. The backlight includes an array of cells (38C). Each cell contains a light source (38) with one or more light-emitting diodes (38D) and a cavity reflector (68) that reflects light from the light source outwardly through a diffuser (34) for use in forming the backlight illumination. The light sources are mounted to a printed circuit (60). Support posts (90) on the printed circuit are used to maintain the diffuser at a fixed distance (H) from the printed circuit. Sensors (104) on the printed circuit are used to measure separation distances between the printed circuit and diffuser. Adjustments to pixel gain profiles can be made based on the measured separation distances to maintain uniform illumination.
