Abstract:
An electronic device may have components such as a display, a camera, a button, and other electrical components. A transparent crystalline member such as a layer of aluminum oxide, zirconium oxide, or other crystalline dielectric structure may overlap an electrical component and may serve as a display cover layer, button cover member, or window member. An annealed adhesion layer such as an annealed inorganic layer may be formed on a crystalline dielectric member. The annealed adhesion layer may help adhere an oleophobic coating to the transparent crystalline member.
Abstract:
An electronic device may include electrical components and other components mounted within an interior of a housing. The device may have a display on a front face of the device and may have a glass layer that forms part of the housing on a rear face of the device. The glass layer may be provided with regions having different appearances. The regions may be textured, may have coatings such as thin-film interference filter coatings formed from stacks of dielectric material having alternating indices of refraction, may have metal coating layers, and/or may have ink coating layers. Textured surfaces may be formed on thin glass layers and polymer films that are coupled to the glass layer. A glass layer may be formed from a pair of coupled glass layers. The coupled layers may have one or more recesses or other structures to visually distinguish different regions of the glass layer.
Abstract:
An electronic device may have a display with a cover layer. An ambient light sensor may be aligned with an ambient light sensor window formed from an opening in a masking layer on the cover layer in an inactive portion of the display. To help mask the ambient light sensor window from view, the ambient light sensor window may be provided with a black coating that matches the appearance of surrounding masking layer material while allowing light to reach the ambient light sensor. The black coating may be formed from a black physical vapor deposition thin-film inorganic layer with a high index of refraction. An antireflection layer formed from a stack of dielectric layers may be interposed between the black thin-film inorganic layer and the display cover layer.

Abstract:
An electronic device may be provided with a display. The display may have a display cover layer. The display may have an active area with pixels and an inactive area without pixels. An opaque masking layer such as a layer of black ink may be formed on the underside of the display cover layer in the inactive area. Windows may be formed from openings in the opaque masking layer. Optical components such as infrared-light-based optical components may be aligned with the windows. The windows may include coatings in the openings that block visible light while transmitting infrared light. The window coatings may be formed from polymer layers containing pigments, polymer layers containing dyes that are coated with antireflection layers, thin-film interference filters formed from stacks of thin-film layers, or other coating structures.

Abstract:
A cover glass including a center region and an outer region abutting the center region at an interface. The interface inhibits crack propagation from the outer region to the center region and vice versa. In another embodiment the cover glass may include mitigation voids introduced into the cover glass to inhibit crack propagation. The interface may be formed from the mitigation voids.
Abstract:
Systems and methods for polishing a ceramic component using a laser. The ceramic component may include a planar region that is polished using, for example, a mechanical or chemical mechanical polishing operation to produce a polished face. A contoured region that is adjacent to the planar region may be irradiated using a laser to heat the ceramic material within the contoured region. The irradiation may reduce the surface roughness of the contoured region to produce a polished surface. The ceramic component may be heated prior to being irradiated with the laser to reduce thermal gradients within the ceramic component.
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 strengthened film for a substrate such as a glass panel is provided. The strengthened film may be formed by implanting sodium in the film, and then performing an exchange through which the sodium is replaced by potassium. The film may be an anti-reflective coating. Related assemblies and methods are also provided.
