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: A variable transmission element includes a first substrate that has a first surface and a second surface opposite the first surface. A second substrate includes a third surface and a fourth surface opposite the third surface. The first and second surfaces face each other and are disposed in a spaced apart relationship so as to define a space therebetween. A seal formed of a sealing material extends along a perimeter of the first and second substrates. A first lamination layer comprises a first lamination material that is different from the sealing material and the first lamination layer is coupled to the second surface. A second lamination layer comprises a second lamination material that is different from the sealing material and the second lamination layer is coupled to the second substrate. An electro-optic device is disposed between the first lamination layer and the second lamination layer.
