Abstract: Electronic devices may be provided with optical components such as displays and sensors that emit and/or detect visible and/or infrared light. The optical components may be mounted in a housing and covered by a textured glass cover layer. The textured glass cover layer may have an antireflection coating formed from a stack of alternating higher index and lower index inorganic dielectric layers. An outermost one of the inorganic dielectric layers may have a hardness greater than quartz to help the antireflection coating resist abrasion. The coating may optionally include a layer of diamond-like carbon to reduce friction and an oleophobic polymer coating to resist fingerprint smudging.
