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: An electro-optic apparatus configured to adjust in transmittance in response to a control input comprises a first web substrate and a second web substrate. Each of the web substrates form a plurality of perimeter edges. A first edge is in connection with a first electrical terminal connecting in connection with a first electrode. A second edge opposing the first edge is in connection with a second electrical terminal in connection with a second electrode. A third edge and an opposing fourth edge comprise a barrier seal in a first configuration in connection with an exterior surface of each of the first web substrate and the second web substrate. The barrier seal encapsulates the electro-optic medium between an interior surface of each of the first web substrate and the second web substrate.

Abstract: A heads up display system of a vehicle includes a combiner screen having a first substantially transparent substrate defining a first surface and a second surface, a second substantially transparent substrate defining a third surface and a fourth surface. 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 material is positioned within the cavity and a transflective layer having a multilayer polymeric film positioned on one of the first and second surfaces, and a projector for projecting light having a first polarization toward the first surface of the first substrate.

Abstract: Anisotropic film laminates for use in image-preserving reflectors such as rearview automotive mirror assemblies, and related methods of fabrication. A film may comprise an anisotropic layer such as a light-polarizing layer and other functional layers. The film having controlled water content is heated under omnidirectional pressure and vacuum to a temperature substantially equal to or above a lower limit of a glass-transition temperature range of the film so as to be laminated to a substrate. The laminate is configured as part of a mirror structure so as to increase contrast of light produced by a light source positioned behind the mirror structure and transmitted through the mirror structure towards a viewer. The mirror structure is devoid of any extended distortion and is characterized by SW and LW values less than 3, more preferably less than 2, and most preferably less than 1.

Abstract: A vehicular rearview assembly with a mirror element having a curved or rounded edge on the first surface that is fully observable from the front of the assembly, a complex peripheral ring, and a user interface with switches and sensors that activate and configure pre-defined function(s) or device(s) of the assembly in response to the user input applied to the user interface. The mirror element is supported by a hybrid carrier co-molded of at least two materials, a portion of which is compressible between the housing shell and an edge of the mirror element. The peripheral ring may include multiple bands. Electrical communications between the electronic circuitry, the mirror element, and the user interface utilize connectors configured to exert a low contact force, onto the mirror element, limited in part by the strength of adhesive affixing the EC element to an element of the housing of the assembly.

Abstract: An imager module for a vehicle includes an imager having an imager lens. The imager is configured to collect image data from at least one of inside and outside the vehicle. A cover is disposed proximate the imager lens and configured to allow the imager to capture image data through the cover. The cover is operable between a first condition, wherein the imager is generally visible through the cover, and a second condition, wherein the imager is generally concealed from view by the cover.

Abstract: An electro-optic assembly for use in a vehicle having a windshield is provided and includes a first arcuate substrate having a first surface with an anti-reflective coating and a second surface. A second arcuate substrate includes a third surface and a fourth surface with an anti-reflective coating. The first and second substrates are positioned such that the second and third surfaces are at least 0.1 mm apart. A seal is disposed between the first and second substrates and located substantially about a periphery of the electro-optic assembly. An electro-optic medium is positioned in a cavity defined by the first substrate, the second substrate, and the seal, the electro-optic medium including a refractive index greater than 1.2. The second surface is configured to receive and reflect incident light projected from a projector, thereby displaying information that appears to be displayed forward of the windshield.
