The invention provides an IG unit comprising two panes and a between-pane space located between the two panes. A desired surface of a selected one of the two panes bears a coating comprising both a transparent conductive oxide film, and an overcoat film located over the transparent conductive oxide film. The IG unit further comprises a bus bar and a transparent conductor bridge each located over the desired surface. The bus bar is spaced apart from the coating and is connected electrically to the transparent conductive oxide film by virtue of the transparent conductor bridge extending from the bus bar to a top surface of the overcoat film. In some embodiments, the IG unit further comprises a frit located over the desired surface and extending around a perimeter thereof. The bus bar is located over the frit. Certain embodiments provide a refrigerator having a door comprising such an IG unit.
A multiple-pane insulating glazing unit comprising two panes and a between-pane space, the between-pane space being located between the two panes, wherein a desired surface of a selected one of the two panes bears a coating comprising both a transparent conductive oxide film and an overcoat film, the overcoat film being located over the transparent conductive oxide film, the multiple-pane insulating glazing unit further comprising a bus bar and a transparent conductor bridge each located over the desired surface, the bus bar being spaced apart from the coating, the bus bar being connected electrically to the transparent conductive oxide film by virtue of the transparent conductor bridge extending from the bus bar to a top surface of the overcoat film.
A multiple-pane insulating glazing unit comprising two panes and a between-pane space, the between-pane space being located between the two panes, wherein a desired surface of a selected one of the two panes bears a coating comprising both an indium tin oxide film and an overcoat film, the overcoat film being located over the indium tin oxide film, the multiple-pane insulating glazing unit further comprising a bus bar and a transparent conductor bridge each located over the desired surface, the bus bar being spaced apart from the coating, the bus bar being connected electrically to the indium tin oxide film by virtue of the transparent conductor bridge extending from the bus bar to a top surface of the overcoat film, the multiple-pane insulating glazing unit further comprising a frit, the frit being located over the desired surface and extending around a perimeter thereof, the bus bar being located over the frit.
A refrigerator having a door comprising a multiple-pane insulating glazing unit, the refrigerator having a refrigerated interior environment, the door having an open configuration and a closed configuration, the multiple-pane insulating glazing unit having an interior face and an exterior face, the interior and exterior faces being opposed, such that when the door is in the closed configuration the interior face is exposed to the refrigerated interior environment while the exterior face is exposed to an ambient environment, the multiple-pane insulating glazing unit comprising two panes and a between-pane space, the between-pane space being located between the two panes, wherein a desired surface of a selected one of the two panes bears a coating comprising both a transparent conductive oxide film and an overcoat film, the overcoat film being located over the transparent conductive oxide film, the multiple-pane insulating glazing unit further comprising a frit, a bus bar, and a transparent conductor bridge each located over the desired surface, the frit extending around a perimeter of the desired surface, the bus bar being located over the frit and being spaced apart from the coating, the bus bar being connected electrically to the transparent conductive oxide film by virtue of the transparent conductor bridge extending from the bus bar to a top surface of the overcoat film.
