ELECTROCHROMIC REARVIEW MIRROR INCORPORATING A THIRD SURFACE METAL REFLECTOR WITH A FLASH OVER-COAT LAYER

摘要

An electrochromic variable reflectance mirror for automotive vehicles is provided. The mirror has front and rear spaced elements, each having front and rear surfaces. The rear surface of the front element has a layer of transparent conductive material disposed thereon. The front surface of the rear element has a reflector/electrode including at least a layer of highly reflective material and a flash over-coat layer. The front and rear spaced elements are sealably bonded together in a spaced-apart relationship to define a chamber. The chamber contains at least one solution-phase electrochromic material in contact with the flash layer. The reflector/electrode is effective to reflect light through the medium and the front element when the light reaches the reflector/electrode after passing through the front element and the at least one electrochromic material. The reflector/electrode is constructed such that the electrochromic variable reflectance mirror exhibits a reflectance of at least 70%.
