    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.

    Abstract: An electronic device may have a rollable display. The display may be moved between an unrolled state in which the display is planar and a rolled state in which a rollable portion of the display is rolled up for storage. The display may have a display panel with a pixel array that produces images and a transparent protective layer that overlaps the pixel array. The transparent protective layer may contain a layer of glass. The glass layer may be locally thinned in the rollable portion to facilitate rolling of the display. The display may be configured to apply compressive stress to the outwardly facing surface of the glass layer when the display is rolled up. Compressive stress in the outwardly facing glass surface may help prevent damage to the display when the display is bent during rolling operations.
