An insulating glass unit, comprising: first and second substrates, each having interior and exterior major surfaces, the interior major surface of the first substrate facing the interior major surface of the second substrate; a spacer system for helping to maintain the first and second substrates in substantially parallel spaced apart relation to one another and to define a gap therebetween; a dynamically controllable shade (202a, 202b) interposed between the first and second substrates, the shade (202a, 202b) including: a first conductive coating provided, directly or indirectly, on the interior major surface of the first substrate; a dielectric or insulator film provided, directly or indirectly, on the first conductive coating; and 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; first and second electrically conductive bus bars located at first and second opposing edges of the first substrate, each of the bus bars (2004, 2006) having first and second ends, the first and second bus bars being at least partially provided, directly or indirectly, on the dielectric or insulator film; and wherein the first and second conductive coatings are configured to be electrically connectable to a power source that is controllable to selectively set up an electric potential difference using the first and second bus bars to correspondingly drive the polymer substrate between the shutter open and closed positions, characterized in that the insulating glass unit further comprising first and second patterns of conductive frit applied, directly or indirectly, to the first substrate, the frit (2002a, 2002b) being interposed between at least the first substrate and the first conductive coating, the first pattern of frit electrically connecting with the first conductive coating, the first and second patterns 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, and 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. first and second substrates, each having interior and exterior major surfaces, the interior major surface of the first substrate facing the interior major surface of the second substrate;
