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.
