    Abstract: An electrochromic device is provided that includes: a first substrate having a first surface and a second surface opposite the first surface, the first substrate having a multilayer polymer film; a first electrode; a second substrate having a third surface and a fourth surface opposite the third surface, the second substrate spaced from the first substrate with the second and third surfaces facing but spaced from one another; a second electrode; and an electrochromic layer positioned between the first and second electrodes. The first electrode is positioned between the second surface and the electrochromic medium and the second electrode is positioned between the third surface and the electrochromic medium. The multilayer polymer film includes a nonpolar polymer layer as an outermost layer closest to the electrochromic medium.

    Abstract: An overmold is disclosed, wherein the overmold may be incorporated into a window assembly. The overmold comprises a base portion and a receiving portion. The receiving portion may comprise a notch or a channel operable to receive a window. The window may be such that when coupled with the overmold, the sides of the overmold and the window are substantially co-planar. Accordingly, window may comprise a first and a second substrate, wherein the second substrate is coupled to a first side of the first substrate. Further, the first substrate may extend beyond the second substrate. Therefore, the overmold, when in abutting contact with the window, may extend onto the first side of the first substrate up to the second substrate.

    Abstract: An improved device switchable between reflective and display states comprising an optical element and a display element. The optical element comprising a liquid crystal medium disposed between first and second substrates. The optical element may further comprise a first electrode, a second electrode, an absorptive polarizer, and a reflective polarizer. The first electrode and the absorptive polarizer may be disposed in a first direction relative the liquid crystal medium. Similarly, the second electrode and the reflective polarizer may be disposed in a second direction relative the liquid crystal medium. The second direction is opposite the first direction. In some embodiments, one or more of the absorptive and reflective polarizers may be further disposed between the first and second substrates. The display may be disposed in the first direction relative the optical element. Additionally, the device may further comprise a housing. In some embodiments, the housing may not have a bezel.

    Abstract: A vehicular rearview assembly includes an electro-optic element. A first substrate defines a first element surface and a second element surface. A first polarizer is coupled to the 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 second substrate. A display is configured to emit light having a first polarization toward the second polarizer.

    Abstract: A display mirror assembly for a vehicle is presented that includes a full display module and an electro-optic element that includes a first substantially transparent substrate having first and second surfaces disposed on opposite sides thereof. The second surface includes a first electrically conductive layer. A second substantially transparent substrate has third and fourth surfaces disposed on opposite sides thereof. The third surface includes a second electrically conductive layer. A primary seal is disposed between the first and second substrates. The seal and the first and second substrates define a cavity therebetween. An electro-optic medium is disposed in the cavity. The electro-optic medium is variably transmissive such that the electro-optic medium is operable between generally clear and darkened states. A first electrical connection and a second electrical connection are positioned on the same side of the electro-optic element.
