    Abstract: An electronic device may have transparent housing structures such as walls formed of glass or sapphire. Housing structures such as transparent housing structures may have a colored coating. The colored coating may include an absorptive layer and a metal layer. The coating may exhibit a color that can be adjusted by adjusting the thickness of the thin absorptive layer. A colored layer such as a layer of colored polymer may be incorporated into the colored coating to further adjust the color of the coating. The colored coating may be formed on an inner or outer housing structure surface. The surface may have a texture to provide the coating with a matte appearance. When formed on an outer surface, a diamond-like carbon layer may protect the colored coating. When formed on an inner surface, a passivation layer may be used to prevent oxidation of the metal layer.

    Abstract: A sapphire structure including an ion-implanted, anti-reflective layer and a method of forming an ion-implanted, anti-reflective layer within a sapphire component is disclosed. The method includes forming an ion-implanted layer in a sapphire material at a first depth, and annealing the sapphire material to a second depth. The second depth may be greater than or equal to the first depth. The ion-implanted layer may have a first index of refraction, and the sapphire material may have a second index of refraction different from the first index of refraction.

    Abstract: An optical device includes a dielectric substrate and a cured resin coating adhered to the substrate. The resin coating includes an organic component and an inorganic component. A surface portion of the resin coating includes greater than about 60 at. % inorganic component and less than about 40 at. % organic component, an intermediate portion includes between about 10 at. % and about 60 at. % inorganic component, and between about 40 at. % and about 90 at. % inorganic component, and a bottom portion includes less than about 10 at. % inorganic component and greater than about 90 at. % organic component. The resin coating has improved hard coat properties and excellent adhesion to a dielectric.

    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.

    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 have transparent members such as display cover layers and camera windows. A transparent member such as a sapphire member may be provided with an antireflection coating. The antireflection coating may have a stack of dielectric thin-film interference filter layers that form a thin-film interference filter that suppresses visible light reflections. The stack of dielectric thin-film interference filter layers may have thicknesses and materials that provide the thin-film interference filter and coating with low light reflection properties while enhancing scratch resistance. An adhesion layer may be used to help adhere the stack of thin-film interference filter layer to the transparent member. An antismudge coating such as a fluoropolymer coating may be used to reduce smudging. Graded layers and layers with elevated hardness values may be used in the coating.
