Abstract
Certain example embodiments relate to 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 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. The shutter includes a resilient polymer, a conductor, and optional ink. The on-glass transparent conductor may be patterned into different areas. If shutter coil skew is detected, voltage(s) may be applied one or more areas of the on-glass transparent conductor to compensate for or otherwise attempt to correct the detected coil skew.
