Abstract: A vehicular rearview assembly, includes a front substrate defining a first surface and a second surface. The front substrate being substantially transparent. The front substrate defines a shaped edge along a periphery of the first surface. A first polarizer is coupled with the second surface. An electro-optic element is coupled to the first polarizer having a first substrate defining a first element surface and a second element surface. A second substrate is spaced away from the first substrate and defines a third element surface and a fourth element surface. An electro-optic material is positioned between the first and second substrates. A second polarizer is coupled to the fourth element surface. A display is configured to emit light having a first polarization into the second polarizer. A reflective layer is positioned between the front substrate and the display is configured to reflect both the first polarization of light and a second polarization of light.

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.

Abstract: A control apparatus for an electro-optic element comprises a first voltage converter in connection with a power supply. The first voltage converter is configured to receive a supply voltage from the power supply and output a first voltage. A first storage capacitor is in connection with the first voltage converter and configured to store first energy at the first voltage. A second storage capacitor is configured to store second energy at a second voltage, wherein the second energy is supplied by the power supply. A driving circuit in conductive connection with the second storage capacitor and configured to supply a driving voltage to the electro-optic element. In response to a failure of the power supply, the first storage capacitor is configured to supply the first energy to a controller and the second storage capacitor is configured to supply the second energy to the driving circuit.
