Abstract: A method of controlling an electroactive device can include operating the electroactive device at an operating parameter for a first period of time, applying a switching voltage having a first magnitude and a first polarity to the electroactive device for a second period of time, and applying a step-wise overshoot voltage having a second magnitude and a second polarity to the electroactive device for a transition period of time. The first magnitude can be greater than the second magnitude, and the first polarity can be the same as the second polarity. The method can also include applying a reverse overshoot voltage having a third magnitude and a third polarity to the electroactive device. The third polarity can be the opposite the second polarity.

Abstract: An apparatus including a substrate with at least three sides and an active stack on the substrate. The active stack can include a first transparent conductive layer, a second transparent conductive layer, an anodic electrochemical layer, and a cathodic electrochemical layer. The apparatus can also include a first bus bar set comprising a plurality of bus bars, wherein each bus bar of the first bus bar set is electrically coupled to the first transparent conductive layer, a second bus bar set comprising a plurality of bus bars, wherein each bus bar of the second bus bar set is electrically coupled to the second transparent conductive layer, and a bus bar arrangement wherein the bus bar arrangement comprises a bus bar from the first bus bar set and a bus bar from the second bus bar set on at least three sides of the substrate.
