摘要： An improved seal member is provided as a part of an electrochromic device to bond two glass elements together in a spaced-apart relationship. In one embodiment the seal member provides improved adhesion to a reflector/electrode on the third surface of an electrochromic mirror, or to a layer of metal on the second or third surface for an electrochromic light filter. This seal member comprises a mixture of an organic resin sealing system and an adhesion promoter, where the adhesion promotor comprises a first and a second region, where the first region interacts with the reflector/electrode or the metal layer, and a second region that interacts with the organic resin sealing system, and may even chemically react with the organic resin sealing system. In another embodiment the seal member is provided with a coefficient of thermal expansion that is closer to glass than a standard epoxy sealing system.

摘要： To allow an electrochromic device to have little or no offset between its front and rear elements, an electrical conductor may be provided to electrically couple a portion of a first conductive layer provided on the rear surface of the front element with a portion of a second conductive layer provided on the front surface of the rear element. The electrical conductor may be in the form of a conductive portion of the seal. To prevent shorting across the electrochromic medium, at least one of the first and second conductive layers is separated into a first portion and a second portion that is electrically isolated from the first portion and is in electrical contact with the electrochromic material. An elastomeric bezel may be utilized. Also, an edge seal may optionally be employed so as to reduce the need or width of the bezel.

摘要： An electrochromic window assembly (10) is disclosed that includes a first substrate (12) and a second substrate (14) that is maintained in a parallel and spaced relation from the first substrate by means of a window frame (16) and spacer (18). The window assembly further includes an electrochromic device (22) mounted in the airtight chamber formed between the first and second substrates. Electrochromic device (22) may be mounted so as to provide an air chamber between first substrate (12), which is the external substrate, and electrochromic device (22). At least one of the chambers formed between substrates (12) and (14) and electrochromic device (22) may be filled with an insulating gas such as argon. Also disclosed are novel methods for manufacture of an electrochromic device for incorporation into such a window assembly. A novel electrochromic device is also disclosed having electrical bus clips (40a, 40b) secured about the entire periphery of the electrochromic device. Also disclosed is the use of steel bus clips for the electrochromic device.

摘要： An electrochromic device is disclosed having a self-cleaning, hydrophilic optical coating. The electrochromic device preferably forms an external rearview mirror for a vehicle The coating preferably includes alternating layers of a photocatalytic material having a high index of refraction and a hydrophilic material having a low refractive index More specifically, the coating includes a first layer having a high refractive index, a second layer having a low refractive index, a third layer of titanium dioxide, and a fourth layer of silicon dioxide provided as an outermost layer. The disclosed optical coating exhibits a reflectance at the front surface of the reflective element that is less than about 20 percent, and has sufficient hydrophilic properties such that water droplets on a front surface of the optical coating exhibit a contact angle of less than about 20°.

摘要： According to one embodiment of the present invention, an electrochromic rearview mirror assembly for a vehicle includes an electrochromic mirror having a variable reflectivity, a glare sensor for sensing levels of light directed towards the front element from the rear of the vehicle, an ambient sensor for sensing levels of ambient light, a display positioned behind the partially transmissive, partially reflective portion of the reflector for displaying information therethrough; and a control circuit coupled to the sensors and the display. The control circuit determines whether daytime or nighttime conditions are present as a function of the ambient light level sensed by the ambient sensor. During daytime conditions, the control circuit responds to light levels sensed by the glare sensor to control a contrast ratio of light originating from the display and light reflecting from the partially transmissive, partially reflective area of the reflector.

摘要： A mirror (110) includes an electro-optic mirror subassembly (111), and a thin-profiled bezel (144) attached around a perimeter of the electrochromic mirror subassembly. The electro-optic mirror subassembly is supported on a carrier by an adheringly bonded heater and foam tape in a laminar arrangement. The bezel may be bonded to an edge of the front surface of the front element of the electro-optic mirror subassembly, and/or may be bonded and/or interlockingly mechanically attached to an edge of the carrier. Alternatively, the bezel can be a strip of paint or thin coating material. The bezel can be molded in place, or can be pre-molded and elastically stretched to permit assembly. In one form, the bezel includes a laterally-extending fin that prevents seeing past the bezel into the inside of a mirror housing.

摘要： An improved seal member is provided as a part of an electrochromic device to bond two glass elements together in a spaced-apart relationship. In one embodiment the seal member provides improved adhesion to a reflector/electrode on the third surface of an electrochromic mirror, or to a layer of metal on the second or third surface for an electrochromic light filter. This seal member comprises a mixture of an organic resin sealing system and an adhesion promoter, where the adhesion promotor comprises a first and a second region, where the first region interacts with the reflector/electrode or the metal layer, and a second region that interacts with the organic resin sealing system, and may even chemically react with the organic resin sealing system.
