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 an array of pixels that display images for a user. The backlight unit may have a light-guide layer. An array of light-emitting diodes may emit light into an edge of the light-guide layer. The light guide layer may overlap a backlight reflector. A quarter wave plate may be interposed between the light guide layer and the backlight reflector. A turning film may be interposed between a lower polarizer in the array of pixels and the light guide layer. The lower polarizer may be a reflective polarizer. Light exiting the upper surface of the turning film may have a dominant polarization. A half wave plate may be used to rotate the dominant polarization into alignment with a pass axis of the reflective polarizer.

Abstract: An electronic device may have a display such as a liquid crystal display. The display may have an array of pixels that display images to a user. Backlight structures may provide the array of pixels with backlight illumination at a backlight illumination level. The backlight structures may have a light source with an array of light-emitting diodes and photoluminescent material that is pumped by pump light from the light-emitting diodes. The backlight illumination may experience color variations as a function of the backlight illumination level. Circuitry in the electronic device may be used to implement a backlight level color compensator. The backlight level color compensator may apply color correction factors to the image data of the displayed images to compensate for variations in color of the image data due to variations in backlight illumination level and operating temperature.
