Abstract: An electronic device may be provided with a display. An opaque layer may be formed on an inner surface of a display cover layer in an inactive area of the display. An optical component window may be formed from the opening. A light guide may be aligned with the optical component window and may be used to guide light from the optical component window to an optical component such as an ambient light sensor. The light guide may have a core surrounded by a cladding. The core may be formed from a material such as blue glass that absorbs infrared light and that transmits visible light. Particles of titanium dioxide or other high-refractive-index material may be incorporated into the core to enhance the refractive index of the core. Thin-film interference filters may be formed on the light guide to enhance infrared light blocking.

Abstract: An electronic device may be provided with a display mounted in a housing. The display may have an array of pixels that form an active area and may have an inactive area that runs along an edge of the active area. An opaque layer may be formed on an inner surface of a display cover layer in the inactive area of the display or may be formed on another transparent layer in the electronic device. An ambient light sensor window may be formed from the opening and may be aligned with color ambient light sensor. The ambient light sensor may have an integrated circuit with an array of photodetectors and may have a color filter layer forming a corresponding array of thin-film interference color filters with different respective pass bands. The color filter layer may have a shared dielectric stack and multiple color-filter-specific dielectric stacks on the shared dielectric stack.
