  • Patent number: 9499435
    Abstract: Certain example embodiments of this invention relate to coated articles including substrates that support printed patterns and thin film layer stacks that can have the patterns and the layer stacks formed thereon and then be cut, heat treated, and optionally built into an insulated glass unit, laminated to another substrate, and/or used in another product. In certain example embodiments, this is made possible by bonding to the glass the frit material used in forming the pattern, re-annealing the glass following the bonding, disposing the thin film layer stack on the re-annealed substrate supporting the bonded pattern, and then cutting and heat treating. The frit advantageously does not re-melt during heat treatment because the melting temperature is higher than the temperature used in heat treatment. Associated methods also are provided.

  • Patent number: 9487437
    Abstract: Certain example embodiments relate to substrates or assemblies having laser-fused frits, and/or methods of making the same. In certain example embodiments, a pattern is formed or written on a stock glass sheet by laser fusing frit material to the glass sheet. An optional thin film coating is disposed on and supported by the stock glass sheet. The stock glass sheet with the pattern and the optional thin film coating is cut prior to heat treatment (e.g., heat strengthening and/or thermal tempering). A YAG or other type of laser source may be used to directly or indirectly heat the frit material, which may be wet applied to the substrate. In certain instances, the laser firing of the frit raises the temperature of the glass substrate to no more than 100 degrees C. and, preferably, the temperature is kept even lower.

  • Patent number: 9469565
    Abstract: A writable window (e.g., IG window unit) is provided where images (e.g., advertisements, logos, designs, pictures and/or words) can be selectively written into the window. A substrate supports a solar coating such as a low emissivity (low-E) coating which may include at least one infrared (IR) reflecting layer (e.g., silver) and a contact/seed layer (e.g., zinc oxide and/or zinc stannate). A radiation source (e.g., laser(s) and/or lamp(s)) selectively exposes certain areas of the coating to radiation (e.g., UV radiation). Exposed area(s) of the coating, after exposure/heating, have different optical characteristic(s) than non-exposed areas, so that exposed area(s) form an image(s) designed to be viewed by humans and/or animals.

  • Patent number: 9469767
    Abstract: Certain example embodiments of this invention relate to articles including anticondensation coatings that are exposed to an external environment, and/or methods of making the same. In certain example embodiments, the anticondensation coatings may be survivable in an outside environment. The coatings also may have a sufficiently low sheet resistance and hemispherical emissivity such that the glass surface is more likely to retain heat from the interior area, thereby reducing (and sometimes completely eliminating) the presence condensation thereon. The articles of certain example embodiments may be, for example, skylights, vehicle windows or windshields, IG units, VIG units, refrigerator/freezer doors, and/or the like.

    Abstract: Certain example embodiments relate to improved lighting systems and/or methods of making the same. In certain example embodiments, a lighting system includes a glass substrate with one or more apertures. An LED or other light source is disposed at one end of the aperture such that light from the LED directed through the aperture of the glass substrate exits the opposite end of the aperture. Inner surfaces of the aperture have a mirroring material such as silver to reflect the emitted light from the LED. In certain example embodiments, a remote phosphor article or layer is disposed opposite the LED at the other end of the aperture. In certain example embodiment, a lens is disposed in the aperture, between the remote phosphor article and the LED.

  • Patent number: 9441415
    Abstract: A window includes a vacuum insulating glass (VIG) window unit in a window frame. The window frame includes at least one vacuum insulated structure (VIS) for improving the insulating functionality of the frame, so that the frame can adequately insulate the periphery of the VIG unit. Such windows may be used in residential and/or commercial window applications for buildings. The use of a window frame having at least one VIS is advantageous in that allows for improved window frame thermal performance and a narrow frame design if desired for improved aesthetics.

  • Patent number: 9434643
    Abstract: Certain example embodiments relate to Ni-inclusive ternary alloy being provided as a barrier layer for protecting an IR reflecting layer comprising silver or the like. The provision of a barrier layer comprising nickel, chromium, and/or molybdenum and/or oxides thereof may improve corrosion resistance, as well as chemical and mechanical durability. In certain examples, more than one barrier layer may be used on at least one side of the layer comprising silver. In still further examples, a NixCryMoz-based layer may be used as the functional layer, rather than or in addition to as a barrier layer, in a coating.

  • Patent number: 9434640
    Abstract: A method of making a heat treated (HT) or heat treatable coated article. A method of making a coated article includes a step of heat treating a glass substrate coated with at least layer of or including carbon (e.g., diamond-like carbon (DLC)) and an overlying protective film thereon. In certain example embodiments, the protective film may be of or include both (a) an oxygen blocking or barrier layer, and (b) a release layer of or including zinc oxide. Treating the zinc oxide inclusive release layer with plasma including oxygen (e.g., via ion beam treatment) improves thermal stability and/or quality of the product. Following and/or during heat treatment (e.g., thermal tempering, or the like) the protective film may be entirely or partially removed.

  • Patent number: 9428952
    Abstract: A vacuum insulated glass (VIG) window assembly and method for making same is provided in which a variation in the final edge seal height is preferably 0.20 mm or less, more preferably about 0.15 mm or less. Controlling final edge seal height variations substantially reduces breakage of the glass substrates of the VIG window assembly during vacuum pump-down of the cavity between the glass substrates. Edge seal height variation may be controlled, for example, by controlling initial dispensing of green frit material, controlling temperature variations during firing, and/or controlling cycle times during firing.

  • Patent number: 9422189
    Abstract: Certain example embodiments relate to substrates or assemblies having laser-fused fits, and/or methods of making the same. In certain example embodiments, a pattern is formed or written on a stock glass sheet by laser fusing frit material to the glass sheet. An optional thin film coating is disposed on and supported by the stock glass sheet. The stock glass sheet with the pattern and the optional thin film coating is cut prior to heat treatment (e.g., heat strengthening and/or thermal tempering). A YAG or other type of laser source may be used to directly or indirectly heat the frit material, which may be wet applied to the substrate. In certain instances, the laser firing of the frit raises the temperature of the glass substrate to no more than 100 degrees C. and, preferably, the temperature is kept even lower.

  • Patent number: 9423533
    Abstract: Certain example embodiments of this invention relate to patterned glass that can be used as a cylindrical lens array in a concentrated photovoltaic application, and/or methods of making the same. In certain example embodiments, the lens arrays may be used in combination with strip solar cells and/or single-axis tracking systems. That is, in certain example embodiments, lenses in the lens array may be arranged so as to concentrate incident light onto respective strip solar cells, and the entire assembly may be connected to a single-axis tracking system that is programmed to follow the East-West movement of the sun. A low-iron glass may be used in connection with certain example embodiments. Such techniques may advantageously help to reduce cost per watt related, in part, to the potentially reduced amount of semiconductor material to be used for such example embodiments.
