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 a housing wall on a rear face of the device. The glass housing wall 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, cavities, coatings, and other decoration may be embedded in glass structures that are joined with chemical bonds at diffusion-bonding interfaces.
Abstract:
Methods and systems for depositing a thin film are disclosed. The methods and systems can be used to deposit a film having a uniform thickness on a substrate surface that has a non-planar three-dimensional geometry, such as a curved surface. The methods involve the use of a deposition source that has a shape in accordance with the non-planar three-dimensional geometry of the substrate surface. In some embodiments, multiple layers of films are deposited onto each other forming multi-layered coatings. In some embodiments, the multi-layered coatings are antireflective (AR) coatings for windows or lenses.
Abstract:
An article includes an optically transparent substrate, an amorphous carbon layer formed on at least a portion of the optically transparent substrate, and an oleophobic layer attached to the optically transparent substrate by the amorphous carbon layer. The oleophobic coating, where present, may be attached to the substrate through the amorphous carbon layer. The article may be used as a cover for an electronic device.
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.
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.

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:
Keycaps for keyboards that have transparent top portions have a set of layered components to define a top surface that provides key definition by curvature, texture, ridges, or other external structural features. Other portions of the keycaps define a glyph or support structure for the top layer. Features such as angle filters and partially reflective materials are implemented to improve the visibility, contrast, and reflectivity of the keycaps. Multiple methods are used to bend or otherwise modify rigid transparent materials such as glass in order to add surface features and to improve aesthetics of the keycaps of a keyboard.
Abstract:
A cover glass assembly comprises a sheet having a first surface and a second surface below the first surface. The second surface comprises a textured portion. The cover glass assembly also includes a pigment layer below the textured portion, and a mirror layer below the pigment layer. The textured portion diffusely reflects a first portion of light that enters the cover glass assembly through the first surface. The pigment layer diffusely reflects a second portion of the light. The mirror layer reflects, onto the pigment layer, a third portion of the light. The cover glass assembly provides a high-luminance surface. A method of forming the cover glass assembly is also disclosed.
