Electric potentially-driven shade with improved electrical connection between internal shade and external power source, and/or method of making the same

A method of making an insulating glass (IG) unit, the method comprising:

• providing first and second substrates, each having interior and exterior major surfaces;
• forming a first conductive coating, directly or indirectly, on the interior major surface of the first substrate;
• providing a dielectric or insulator film, directly or indirectly, on the first conductive coating;
• locating, adjacent to the dielectric or insulator film, a shutter including a polymer substrate supporting a second conductive coating, wherein the polymer substrate is extendible to serve as a shutter closed position and retractable to serve a shutter open position;
• providing first and second electrically conductive bus bars at first and second opposing edges of the first substrate, each of the bus bars having first and second ends, the first and second bus bars being provided, directly or indirectly, on the dielectric or insulator film;
• applying first and second patterns of conductive frit, directly or indirectly, to the first substrate, the frit being interposed between the first substrate and the first conductive coating, the first pattern of frit electrically connecting with the first conductive coating, the first and second pattern extending along third and fourth opposing edges of the first substrate, the first through fourth edges being different from one another, the first pattern extending in a direction from the first end of the first bus bar towards the first end of the second bus bar, the second pattern extending in a direction from the second end of the first bus bar towards the second end of the second bus bar;
• electrically connecting the first and second conductive coatings to a power source, wherein the first conductive coating, dielectric or insulator film, and shutter at least partially form a dynamic shade that is controllable in connection with the power source and using the first and second bus bars to selectively set up an electric potential difference and correspondingly drive the polymer substrate between the shutter open and closed positions;
• and
• connecting the first and second substrates together in substantially parallel spaced apart relation to one another in connection with a spacer system such that the interior surfaces of the first and second substrates face one another in making the IG unit, a gap being defined therebetween, the dynamic shade being interposed between the first and second substrates in the gap.
