Abstract: An electro-optic device includes a first substrate that has a first surface and a second surface. A second substrate has a third surface and a fourth surface. A first electrode layer is associated with the second surface. A second electrode layer is associated with the third surface. An electro-optic medium is disposed between the first and second electrode layers. The electro-optic medium is operable between substantially activated and substantially unactivated states based on changes to an electrical potential between the first and second electrode layers. At least one third electrode layer is disposed adjacent to one of the first electrode layer and the second electrode layer. At least one light source operably electrically interposes the at least one third electrode layer and the one of the first electrode layer or the second electrode layer that is adjacent to the at least one third electrode layer.

Abstract: An electro-optic element is disclosed. The electro-optic element may comprise a voltage control device electrically connected to an electrode of the electro-optic medium. In some embodiments, the voltage control device may be a transistor. The voltage control device may be operable to receive a supply voltage and to output an activation voltage to an electro-optic medium of the electro-optic element. Additionally, the electro-optic element may further comprise a control circuit. The control circuit may be configured to receive at least one feedback signal. Based, at least in part, on the feedback signals, the control circuit may accordingly control the activation voltage output by the voltage control devices.
