A radio-wave transmitting substrate includes a dielectric substrate, and, on at least one main surface of the dielectric substrate, a heat-ray reflection film including an electroconductive film, and an opening where the electroconductive film is absent in a plan view. At least a part of the at least one main surface in a plan view is a radio-wave transmitting region. The radio-wave transmitting region is a region where every 1-cm square unit region in the region satisfies the following expression (a): L>802.6×S−503.7. L is an overall length (unit: mm/cm.sup.2) of a boundary between the heat-ray reflection film and the opening in the unit region, and S is a proportion of an area occupied by the heat-ray reflection film in the unit region.

Provided are novel energy-efficient signal-transparent window assemblies and methods of fabricating thereof. These window assemblies are specifically configured to allow selective penetration of electromagnetic wavelengths greater than 0.5 millimeters, representing current and future wireless signal spectrum. This signal penetration is provided while IR blocking properties are retained. Furthermore, the windows assemblies remain substantially transparent within the visible spectrum with no specific features detectable to the naked eye. This unique performance is achieved by patterning conductive layers such that the conductive layer edges remain protected during most fabrication steps and the fabrication. As such, the conductive layers are encapsulated and being separated from the environment while retaining separation between individual disjoined structures of these layers. For example, a barrier layer and/or a dielectric layer may extend over the conductive layer edge. The patterning is achieved by forming photoresist structures on the substrate and depositing a low-E stack over these photoresist structures.

The invention provides low-emissivity coatings that are highly reflective of infrared radiation. The coating includes three infrared-reflection film regions, which may each comprise silver.

A low-emissivity (low-E) coating on a substrate (e.g., glass substrate) includes at least first and second infrared (IR) reflecting layers (e.g., silver based layers) that are spaced apart by contact layers (e.g., NiCr based layers), a layer comprising silicon nitride, and an absorber layer of or including a material such as niobium zirconium which may be oxided and/or nitrided. The absorber layer is designed to allow the coated article to realize glass side reflective (equivalent to exterior reflective in an IG window unit when the coating is provided on surface #2 of an IG window unit) silver color. In certain example embodiments, the coated article (monolithic form and/or in IG window unit form) has a low visible transmission (e.g., from 15-45%, more preferably from 22-39%, and most preferably from 24-35%). In certain example embodiments, the coated article may be heat treated (e.g., thermally tempered and/or heat bent).

A low-E coating has good color stability (a low ΔE* value) upon heat treatment (HT). Thermal stability may be improved by the provision of an as-deposited crystalline or substantially crystalline layer of or including zinc oxide, doped with at least one dopant (e.g., Sn), immediately under an infrared (IR) reflecting layer of or including silver; and/or by the provision of at least one dielectric layer of or including an oxide of zirconium. These have the effect of significantly improving the coating's thermal stability (i.e., lowering the ΔE* value). An absorber film may be designed to adjust visible transmission and provide desirable coloration, while maintaining durability and/or thermal stability. The dielectric layer (e.g., of or including an oxide of Zr) may be sputter-deposited so as to have a monoclinic phase in order to improve thermal stability.

A heating device equipped with a chamber defining a cavity, includes a door or wall incorporating a triple glazing including three transparent substrates defining, from the interior to the exterior of the cavity, faces numbered 1 to 6 respectively, at least the faces 1 and 2 of the first substrate and 3 and/or 4 of the second substrate being covered with heat-reflecting coatings, wherein the mean spacing e1 between the first substrate and the second substrate and the mean spacing e2 between the second substrate and the third substrate is different, the ratio between the largest spacing and the smallest spacing being greater than 1.1, and e1 and e2 being between 2 and 20 mm.

Certain example embodiments of this invention relate to techniques for laser ablating/scribing peripheral edges of a coating (e.g., a low-emissivity, mirror, or other coating) on a glass or other substrate in a pre- or post-laminated assembly, pre- or post-assembled insulated glass unit, and/or other product, in order to slow or prevent corrosion of the coating. For example, a 1064 nm or other wavelength laser may be used to scribe lines into the metal and/or metallic layer(s) in a low-emissivity or other coating provided in an already-laminated or already-assembled insulated glass unit or other product, e.g., around its periphery. The scribe lines decrease electron mobility from the center of the coating to the environment and, thus, slow and sometimes even prevent the onset of electrochemical corrosion. Associated products, methods, and kits relating to same also are contemplated herein.

A transparent structure may have structural layers such as an inner layer and an outer layer, which may be formed from glass. The transparent structure may be curved. At least one of the inner layer and the outer layer may be coated with an infrared reflection coating. The infrared reflection coating may be formed from multiple optical resonators. Each of the resonators may include two half-mirrors separated by a dielectric layer. The half-mirrors may include infrared reflective material, such as silver. At least some of the resonators may additionally include a getter layer. The getter layer may be formed from amorphous material, nanoparticles in dielectric material, or other desired material, and may protect the infrared reflective material while the infrared reflection coating is being deposited. Additionally, the getter layer may reduce the color shift exhibited by high angle light as it passes through the transparent structure.

A head-up display system with an imaging unit for generating an image on a projection surface is described. The projection surface is provided for reflecting at least a part of the image. The projection surface includes a transparent screen having a transparent substrate and at least one electrically conductive coating with at least one functional layer on at least one surface of the transparent substrate.
