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.
