  • Patent number: 9061481
    Abstract: Certain example embodiments relate to robust semi-transparent coatings that are suitable for use in a wide variety of display-on-demand mirror applications, and methods of making the same. In certain example embodiments, a coated article includes a coating supported by a glass substrate. A reflective metal-inclusive layer is formed, directly or indirectly, on the glass substrate. A silicon oxide inclusive layer is formed, directly or indirectly, on the reflective metallic layer. A titanium oxide inclusive layer is formed, directly or indirectly, on the silicon oxide inclusive layer. The metal-inclusive layer is formed so as to reflect incoming light away from the glass substrate such that substantially less incoming light would be reflected away from the glass substrate if lighting were provided on a side of the glass substrate opposite the coating than if no lighting were provided. The surface of the coated article need not necessarily be conductive.

  • Patent number: 7879448
    Abstract: A coated article is provided that may be heat treated in certain example embodiments. A coating of the coated article includes a zinc oxide inclusive layer located over and contacting a contact layer that is in contact with an infrared (IR) reflecting layer of a material such as silver. It has been found that the use of such a zinc oxide inclusive layer results in improved thermal stability upon heat treatment, increased visible transmission, and/or lower sheet resistance (Rs).

  • Publication number: 20100255980
    Abstract: This invention relates to a high transmission low iron glass that includes boron oxide. The boron oxide, added to this low iron glass, has the effect of improving glass refining, homogeneity and quality (lower seed count) through its flux action and improves glass optical parameters of green and clear glass through the change in refractive index and surface tension. Boron oxide lends to broader and weaker absorption band of such transition element(s) as iron which additionally improves the transmittance of low iron clear glass in certain example embodiments of this invention. In certain example embodiments, the addition of boron oxide in certain quantities in advantageous in that it improves the chemical durability of the glass by decreasing the USPX (or USPXIII) value of the glass via suppression of the silica, sodium ions in the glass structure.
