    摘要： A system may have an external display that presents content to viewers outside of the system. The external display may have a display panel with an array of pixels formed from light-emitting diodes. Optical films that help collimate and homogenize light from the light-emitting diode pixels may overlap the light-emitting diodes. A transparent cover may overlap the display. The transparent cover may have an outer surface and an opposing inner surface. The outer surface and inner surface may be planar or may have a curved cross-sectional profile. An optical louver layer or other solar rejection layer may be interposed between the inner surface of the transparent cover and the display panel. The louver layer may have a series of elongated parallel louvers formed from an opaque polymer or other material. The louvers may be configured to block sunlight reflections while allowing images on the display panel to be viewed.

    摘要： An electronic device may include a projection display that has a high transparency when the display is turned off. The high off-state transparency may create the appearance of the display being invisible in the off-state, which may be desirable in certain electronic devices. The projection display may include an adjustable diffuser, a spatial light modulator that projects images onto the adjustable diffuser, a mirror that reflects the images from the spatial light modulator to the adjustable diffuser, and a light source that provides light to the spatial light modulator. The projection display may also include an adjustable opacity layer that is controlled based on detected ambient light levels. The projection display may also include an adjustable reflectivity layer. The adjustable diffuser and/or light source may be pixelated to increase contrast in the projection display.

    摘要： 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.

    摘要： 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.

    摘要： 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.
