    Abstract: An electronic device may be surrounded by an exterior region and may have an interior region. Electronic components may be mounted in the interior region. Housing walls such as housing walls formed from transparent layers of material may separate the interior region from the exterior region. A display may be visible through one of the transparent layers of material. A transparent layer of material may be coupled to housing structures in the device and may be formed of glass or glass-ceramic. The transparent layer may have two opposing chemically strengthened surface layers of different thicknesses. A coating may be formed on a thinner of the two opposing chemically strengthened surface layers. The coating may have an oleophobic outer coating layer, an antireflection layer, and an antiscratch layer. The antiscratch layer may have one or more compressively stressed dielectric layers and may have one or more corresponding graded composition layers.

    Abstract: An electronic device may have a display and a rear housing. A coating may be formed on an inner surface of a display cover layer for the display or on an inner surface of the rear housing. The coating may include one or more inorganic layers such as inorganic layers in a thin-film interference filter or other layer of material. A buffer layer having a polymer with adhesion promotion additive and embedded silicon oxide particles may be interposed between the coating and a glass layer forming the rear housing or between a patterned indium tin oxide coating on a display cover layer and an adhesive layer that attaches a pixel array to the display cover layer.

    Abstract: A transparent component of an electronic device having a nano-crystalline layer is disclosed. The nano-crystalline layer may be formed as a series of layers separated by or interspersed with one or more other layers including a non-crystalline or amorphous material. The series of layers may also be interspersed with one or more anti-reflective layers configured to reduce optical reflections off the transparent component. The nano-crystalline layer may be formed by a deposition process or by an ion-implanting and annealing process to form crystals having a size of less than 10 nanometers. The protective coatings may be utilized on portions of an electronic device, such as a housing or a cover glass, to protect the electronic device from scratching and/or damage caused by impact.

    Abstract: A graded index antireflection layer may be formed on a transparent crystalline member such as a sapphire member. The graded index layer may include aluminum oxide and silicon oxide. The graded index layer may extend from a first surface at the transparent member to a second surface. The fraction of aluminum oxide in the graded index layer may be at a maximum at the first surface so that the index of refraction of the graded index layer at the first surface matches the index of refraction of the transparent member and may be at a minimum at the second surface so the index of refraction of the graded index layer is minimized at the second surface. The graded index layer may be annealed to form aluminum oxide nanocrystals in the graded index layer and to form a polycrystalline aluminum oxide adhesion layer at the first surface.
