Abstract:
A video mirror system for a vehicle comprising an interior rearview mirror assembly having a transflective electro-optic reflective element that transmits at least about ten percent of visible light incident thereon and reflects at least about sixty percent of visible light incident thereon. A display module is disposed at a rear of the transflective electro-optic reflective element and comprises a plurality of individual light sources. A thermally conductive element may be in substantial thermal contact with the display module and is exposed at a rear casing portion of the mirror assembly so as to draw heat generated by the display module away from the display module and to the exterior of the interior rearview mirror assembly. The exposure of the thermally conductive element at the rear casing portion may be substantially not discernible to a viewer viewing the rear casing portion of the interior rearview mirror assembly.
Abstract:
A display mirror assembly includes a reflective mirror element having a semitransparent mirror reflector coated onto a light-transmitting substrate. Visible light transmission through the reflective mirror element is at least 3 percent and visible light reflectance by the reflective mirror element is at least 40 percent for visible light incident upon the front side of the reflective mirror element. The reflective mirror element does not exhibit substantial spectral selectivity in its reflectance of visible light incident upon its front side. A display device is disposed to the rear of the reflective mirror element and configured so that light emitted by the display device passes through the semitransparent mirror reflector to be viewed by a viewer viewing from the front. When electrically powered, a display luminance of at least about 60 foot lamberts as measured with said display device placed behind, and emitting light through, the reflective element is achieved.
Abstract:
A mirror assembly for a vehicle includes a mirror element having at least one substrate that has a forward surface and a rearward surface. The mirror element comprises at least one substantially reflective metallic layer sandwiched between a respective pair of substantially transparent non-metallic layers. Each of the substantially transparent non-metallic layers and the substantially reflective metallic layer have a selected refractive index and a selected physical thickness such that the reflective element is selectively spectrally tuned to substantially transmit at least one preselected spectral band of radiant energy therethrough while substantially reflecting other radiant energy. A radiant energy emitting element is disposed at or near the rearward surface of the at least one substrate. The radiant energy emitting element is configured to emit radiant energy with a peak intensity within the at least one preselected spectral band.

Abstract:
A variable reflectance mirror reflective element assembly for an exterior mirror assembly includes a heater pad disposed at the fourth surface of the rear substrate. The heater pad includes a first connector that electrically connects with the transparent electrically conductive coating disposed at the second surface of the front substrate, and a second connector that electrically connects with the metallic electrically conductive coating disposed at the third surface of the rear substrate. The heater pad includes third and fourth connectors that provide, at least in part, electrical conductive connection with a heating element. The connectors are part of a unitary multi-pin connector that is configured to connect with a corresponding wire harness connector to provide electrical power to the heating element and to the transparent electrically conductive coating and the metallic electrically conductive coating of the reflective element when the exterior minor assembly is mounted at the vehicle.
Abstract:
A rearview mirror element assembly includes an electrochromic reflective element having a primary viewing region operable to exhibit electrically variable reflectivity, with a specularly reflective mirror reflector established at a third surface of a rear substrate at the primary viewing region. An auxiliary viewing region provides an auxiliary wide angle view of a blind spot to the side of a vehicle when the electrochromic reflective element is used in an exterior rearview mirror assembly mounted at a side of a vehicle. A specularly reflective demarcating layer is established at a second surface of a front substrate of the electrochromic reflective element and, at least in part, is visible through the front substrate to a viewer when viewing the first surface of the front substrate of the electrochromic reflective element. The demarcating layer at least partially traverses the reflective element adjacent the auxiliary viewing region.

A variable reflectance vehicular electro-optic rearview mirror reflective element assembly includes a front substrate and a rear substrate and a perimeter seal disposed therebetween. The front substrate has a first surface and a second surface that has a transparent electrically conductive coating disposed thereat. The rear substrate has a third surface and a fourth surface, with the third surface having a conductive coating disposed thereat. The perimeter seal spaces the front and rear substrates apart and forms an interpane cavity therebetween. The third surface conductive coating includes a plurality of layers, which includes a first layer of nickel chromium. The first layer of nickel chromium is overcoated with a silver or silver alloy layer, and the silver or silver alloy layer is overcoated with a second layer of nickel chromium, and the second layer of nickel chromium is overcoated with a reflective layer.

A vehicular interior rearview mirror assembly includes an electro-optic reflective element, a photo sensor and a light concentrator. The electro-optic reflective element has a front substrate with a first surface and a transparent second surface electrically conductive coating disposed on a second surface, and the electro-optic reflective element has a rear substrate with a third surface transflective metallic reflector disposed at a third surface thereof. The photo sensor is disposed behind a fourth surface of the rear substrate and operable to detect light passing through the transflective metallic reflector and the electro-optic reflective medium disposed between the second and third surfaces. The light concentrator is disposed between the photo sensor and the fourth surface of the rear substrate, and the light concentrator receives light passing through the transflective metallic reflector of the electro-optic reflective element and concentrates light onto a light sensing surface of the photo sensor.
Abstract:
A vehicular blind spot indicator mirror includes a transparent glass substrate having a mirror reflector coated onto the substrate. Visible light reflectance by the mirror reflector coated substrate is at least about 40 percent visible light reflectance for visible light incident upon a front side of the mirror reflector coated substrate. A blind spot indicator light display is disposed to the rear of the mirror reflector coated substrate and emits visible light upon a detection by a blind spot detector. Light emitted by the display passes through the transparent glass substrate to be viewed by a viewer viewing from the front side of the substrate. The display is operable, when electrically powered and when operated in the vehicle during day time driving conditions, to exhibit a display luminance of at least about 60 foot lamberts as measured with the display placed behind, and emitting light through, the transparent glass substrate.
Abstract:
An interior rearview mirror reflective element includes a front substrate connected with a rear substrate via a perimeter seal, whereby, when so connected, at least a portion of a circumferential outer edge of the rear substrate is inward of a circumferential outer edge of the front substrate and no portion of the rear substrate protrudes beyond the front substrate. A first electrical connection establishes electrical connection at the front substrate and a second electrical connection may establish electrical connection at the rear substrate. An electrically conductive perimeter hiding band is disposed around a border region of the front substrate and substantially hides the seal and the electrical connections from view by a driver normally operating the vehicle and viewing the reflective element when the interior rearview mirror assembly is normally mounted in the vehicle.
