Abstract: An electronic device may have one or more displays that produce images for a user. The display may include an array of light-emitting diodes. Each light-emitting diode in the array of light-emitting diodes may include a plurality of vias. The vias may be arranged in an array of rows and columns. The light-emitting diodes in the array may share a common cathode. The common cathode may include a conductive layer formed from a reflective material. The conductive layer may be formed in a grid that defines a plurality of openings for the light-emitting diodes or may be formed around the periphery of the array. The array may include light-emitting diodes of two different colors in a head-to-tail arrangement, connected in series, or that share a common cathode. The array may include light-emitting diodes of three different colors that are vertically stacked.

Abstract: A system may have a display that includes a plurality of light sources such as light-emitting diodes. The display may be an exterior display that is routinely operated in daytime conditions where ambient light levels are very high. To increase contrast in an exterior display, the display may include a sunlight blocking element. A static sunlight blocking element may include a louver film with asymmetric light blocking portions. The system may include an ambient light sensor that is configured to determine ambient light levels. Based on the detected ambient light level, control circuitry in the system may adjust one or more adjustable components in the display. The display may include an adjustable diffuser that has at least two states with different haze levels. The display may include an adjustable tint layer that has at least two states with different transmission levels.

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.
