Patent number: 8329304Abstract: A plasma display panel (PDP) includes an EMI filter supported by a glass substrate for blocking/shielding substantial amounts of electromagnetic waves, with the filter being supported by a side of the substrate opposite a viewer. In certain example embodiments, a black frit and a silver frit comprise a filter frame and are supported by the filter such that the filter is closer to the glass substrate than either or both of the frits. Alternatively, in certain example embodiments, a conductive black frit comprises a filter frame and is supported by the filter such that the filter is closer to the glass substrate than the frit. The filter has high visible transmission, and is capable of blocking/shielding electromagnetic waves. Advantageously, a transparent conductive coating (TCC) can be coated on a stock, non-cut glass sheet.Type: GrantFiled: August 21, 2008Date of Patent: December 11, 2012Assignee: Guardian Industries Corp.Inventors: Yei-Ping (Mimi) H.

Patent number: 8318329Abstract: The radiation-selective absorber coating (20) has two barrier layers (24a, 24b), an IR-reflecting layer (21) arranged thereon, an absorption layer (22) arranged above the IR-reflecting (21) and an antireflection layer (23) over the absorption layer (22). The absorber tube (13) is a steel tube (1) with the radiation-selective absorber coating (20) applied to the outside thereof. In the process of coating the absorber tube (13) a first oxide barrier layer (24a) is applied to a steel tube by thermal oxidation; a second barrier layer (24b) is then applied by physical gas phase deposition of silicon with supply of oxygen; the IR-reflecting layer (21) is then applied by gas phase deposition of gold, silver, platinum or copper; the absorption layer (22) is then applied by deposition of aluminum and molybdenum; and a final antireflection layer (23) is applied by deposition of silicon with supply of oxygen.Type: GrantFiled: February 17, 2009Date of Patent: November 27, 2012Assignee: Schott AGInventors: Kamel Silmy, Jan Schulte-Fischedick, Thomas Kuckelkorn, Christina Hildebrandt, Wolfgang Graf, Andreas Georg

Patent number: 8304072Abstract: 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.Type: GrantFiled: October 7, 2008Date of Patent: November 6, 2012Assignee: Guardian Industries Corp.Inventors: Desaraju V.

Patent number: 8304045Abstract: 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.Type: GrantFiled: May 10, 2010Date of Patent: November 6, 2012Assignee: Guardian Industries Corp.Inventors: Jean-Marc Lemmer, Nestor P.
