An electronic device may have transparent housing structures such as walls formed of glass or sapphire. Housing structures such as transparent housing structures may have a colored coating. The colored coating may include an absorptive layer and a metal layer. The coating may exhibit a color that can be adjusted by adjusting the thickness of the thin absorptive layer. A colored layer such as a layer of colored polymer may be incorporated into the colored coating to further adjust the color of the coating. The colored coating may be formed on an inner or outer housing structure surface. The surface may have a texture to provide the coating with a matte appearance. When formed on an outer surface, a diamond-like carbon layer may protect the colored coating. When formed on an inner surface, a passivation layer may be used to prevent oxidation of the metal layer.

Aspects of the present disclosure relate generally to methods and apparatus of processing transparent substrates, such as glass substrates. In one implementation, a film stack for optical devices includes a glass substrate including a first surface and a second surface. The film stack includes a device function layer formed on the first surface, a hard mask layer formed on the device function layer, and a substrate recognition layer formed on the hard mask layer.

The present disclosure relates to a method for forming a glass, ceramic or composite material. The method may involve initially forming a plurality of tubes and then performing a coating operation to coat the plurality of tubes with materials containing metal or metalloid elements, including inorganic compounds, organometallic compounds, or coordination complexes to form coated tubes. The method may further include performing at least one of a thermal operation or a thermochemical operation on the coated tubes to form a solid glass, ceramic, or composite structure with dimensions representing at least one of a rod or fiber.

A mask blank glass substrate having a maximum value of a circularly averaged power spectral density of 1,000 nm.sup.4 or less at a spatial frequency of 0.1 μm.sup.−1 or more and 20 μm.sup.−1 or less, the maximum value being obtained by measuring a surface morphology of a region of 10 μm×10 μm with an atomic force microscope.

A projection assembly for a head-up display (HUD) includes a windshield, including an outer and inner pane joined to one another via a thermoplastic intermediate layer, and having an HUD region; and a projector directed at the HUD region. The radiation of the projector is predominantly p-polarised, and the windshield is provided with a reflective coating, which is suitable for reflecting p-polarised radiation. The reflective coating has exactly one electrically conductive layer and arranged one above and one below the electrically conductive layer are two dielectric layer sequences, each including n low-optical-refraction layers having an index of refraction less than 1.8 and (n+1) high-optical-refraction layers having an index of refraction greater than 1.8, arranged alternatingly in each case, wherein n is an integer greater than or equal to 1.

Black-coloured article (1) which is not a photovoltaic device, comprising:—a substantially transparent substrate (3);—a substantially transparent textured layer (5) provided upon a first surface (3a) of said substrate, said textured layer (5) having a textured surface (5a) oriented away from said substrate (3);—an absorption layer (7) comprising silicon-germanium alloy, said absorption layer (7) being situated upon said textured surface (5a) of said textured layer (5).

A low-E (low emissivity) coating includes a multilayer overcoat designed for reducing fingerprints. The multilayer overcoat includes a layer comprising an oxide of zirconium (e.g., ZrO.sub.2) sandwiched between and contacting first and second layers of or including silicon nitride (e.g., Si.sub.3N.sub.4, SiO.sub.xN.sub.y, SiZrO.sub.xN.sub.y, or the like). The uppermost layer comprising silicon nitride modifies the surface energy of the layer comprising the oxide of zirconium so as to make the uppermost surface of the coating more hydrophilic, thereby reducing or minimizing interaction between zirconium oxide and finger oil to reduce fingerprints on the uppermost surface of the coating.
