Abstract (en)

[origin: WO2022144705A1] Electric, potentially-driven shades usable with insulating glass (IG) units, IG units including such shades, and/or associated methods. In such a unit, a dynamic shade is located between the substrates (102, 104) defining the IG unit, and is movable between retracted and extended positions. The dynamic shade includes on-glass layers including a transparent conductor and an insulator or dielectric film, as well as a shutter (312). The shutter includes a resilient polymer- based layer and a conductive layer. A first voltage is applied to the transparent conductors to cause the shutter to extend to a closed position, and a second voltage is applied to a stop (504) to electrostatically hold the shutter (312) in the closed position. The first and second voltage levels can be reduced once the shutter (312) is extended to the closed position, the reduction to the first voltage level being greater than the reduction to the second voltage level.
