Abstract: An electro-optic element having multiple regions is disclosed. The electro-optic element comprises an electro-optic medium disposed between two electrodes. Further, the electro-optic medium is operable between activated and un-activated states based, at least in part, on exposure to an electrical potential. In some embodiments, in response to an electrical potential of a first polarity, the electro-optic medium may be substantially activated in one region and substantially un-activated in another region. In response to an electrical potential of a second polarity opposite the first polarity, the electro-optic medium may be substantially activated in both regions. In other embodiments, the electro-optic medium is operably activated such that electro-optic medium is activated in one region and un-activated in another region, regardless of polarity.

Abstract: An electro-optic apparatus configured to adjust in transmittance in response to a control input comprises a first web substrate and a second web substrate. Each of the web substrates form a plurality of perimeter edges. A first edge is in connection with a first electrical terminal connecting in connection with a first electrode. A second edge opposing the first edge is in connection with a second electrical terminal in connection with a second electrode. A third edge and an opposing fourth edge comprise a barrier seal in a first configuration in connection with an exterior surface of each of the first web substrate and the second web substrate. The barrier seal encapsulates the electro-optic medium between an interior surface of each of the first web substrate and the second web substrate.

Abstract: An improved electro-optic element is disclosed. The electro-optic element may comprise a first substrate, a second substrate, a first electrode, a second electrode, and/or an electro-active medium. The first electrode may be associated with a surface of the first substrate. Likewise, the second electrode may be associated with a surface of the second substrate. The first and second substrates may be disposed in a substantially parallel, spaced apart relationship relative one another such that the first and second electrode face one another. The electro-active medium may be disposed between the first and second electrodes. Additionally, each of the first and second electrodes may comprise a conductive mesh and a layer. The layer may be electrically conductive and associated with an inner side of the mesh. Accordingly, the layer may serve as a lateral electrical distributor such that the electrical potential may be substantially uniform across the electrode.

Abstract: An electro-optic element includes a first substantially transparent polymer substrate defining first and second surfaces. The second surface includes a first electrically conductive layer. A first polymer multi-layer film is disposed between the first substrate and the first conductive layer. The first polymer multi-layer film includes a first polymer layer, an inorganic layer, and a second polymer layer. A second substantially transparent substrate defines a third surface and a fourth surface. The third surface includes a second electrically conductive layer. An electrochromic medium is disposed in a cavity defined between the first and second substrates and includes a cathodic material, an anodic material, and at least one solvent.
