Abstract: An electronic device may be provided with a display mounted in a housing. A color sensing ambient light sensor may measure the color of ambient light. The color sensing ambient light sensor may be mounted in alignment with an ambient light sensor window formed in an inactive area of the display. The color sensing ambient light sensor may be formed from detectors on a semiconductor substrate. The detectors may include detectors that have spectral sensitivity profiles matching those of color matching functions. The color sensing ambient light sensor may include an infrared light detector. Light redirecting structures such as a diffuser, prism film, negative lens film, or privacy film may be used in directing light into the ambient light sensor. The color sensing ambient light sensor may be calibrated by exposing the sensor to light sources of different types.

Abstract: An electronic device may be provided with light sensors. The electronic device may have an electronic device housing in which a display is mounted. The display may have a transparent layer such as a transparent display cover layer, a thin-film transistor layer, or a color filter layer. An opaque masking layer such as a layer of black ink may be used to cover an inner surface of the transparent layer in an inactive area of the display. Sensor window openings may be formed in the black ink layer. A layer of ink may be formed in each sensor window opening. Each layer of ink may have a diffuse reflectivity that is matched to that of the black ink. A diffuser layer such as a polymer coating layer with light-scattering particles may be coated on the inner surface of the layer of ink in a sensor window opening.
