Abstract
An insulated glazing unit includes a spacer defining a framed area, first and second glazing panes attached to the spacer, a pane conductive layer on an inner surface of the first glazing pane, and a dielectric layer disposed on the pane conductive layer. A shade for use with the insulated glazing unit is affixed to the first glazing pane. The shade includes one or more layers selected from a resilient layer, a substantially transparent shade conductive layer, and an opaque shade conductive layer. When an electric drive is applied between the pane conductive layer and the shade conductive layer, a potential difference between the pane conductive layer and the shade conductive layer causes the shade to extend from a retracted configuration to an extended configuration. The shade can further include at least one ink coating layer including pigments that selectively reflect or absorb certain visible colors and infrared.
