Abstract: A system may have an exterior display. The exterior display may display symbols that correspond to intended actions for the system or instructions for nearby viewers. The exterior display may include an array of light-emitting diodes, a collimator, a one-way filter to prevent sunlight from washing out the display, and a cover layer. The one-way filter may include a microlens array and a masking layer. The collimator is configured to collimate light from the array of light-emitting diodes and provide the collimated light to the one-way filter. The microlens array receives the collimated light and focuses the collimated light through a plurality of holes in the masking layer. In this way, the majority of display light is passed through the one-way filter towards a viewer. However, the majority of ambient sunlight is blocked by the masking layer, thus preserving a high contrast for the exterior display even in bright sunlight.

Abstract: 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.

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 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, which may have areas of compound surface curvature. Louvers that serve to reduce off-axis solar light reflections while allowing light from the display panel to be emitted may be formed from molded polymer supported by a transparent cover layer in the cover. A diffuser may be formed by embedding light-scattering particles in a polymer layer covering the louvers and/or by forming light-scattering surface structures such as ridges and/or other texture on the surface of the polymer layer. Electrically adjustable light modulator layers and electrically adjustable louvers may be used in the display.
