Abstract:
1. A rearview mirror system for a vehicle comprising: a rearview mirror assembly comprising an electrochromic mirror reflective element having electrically variable reflectivity between a high reflectance state and a dimmed reflectance state; said electrochromic mirror reflective element comprising a front substrate having a first surface and a second surface; said electrochromic mirror reflective element comprising a rear substrate having a third surface and a fourth surface; said second surface of said front substrate and said third surface of said rear substrate opposing each other in said electrochromic mirror reflective element and with an electrochromic medium disposed therebetween; a specularly reflecting mirror reflector established at said third surface of said rear substrate, said specularly reflecting mirror reflector having a reflectance value of at least about 70 percent of light incident thereon; a specularly reflecting indicia reflector locally established at said second surface of said front substrate to form indicia at said reflective element, said specularly reflecting indicia reflector having a reflectance value of light that passes through said front substrate to be incident thereon that is at least about 5 percent less than that of said specularly reflecting mirror reflector; and the indicia providing a visible contrast between light incident at said mirror reflector and light incident at said indicia reflector so that when said electrochromic mirror reflective element is in its high reflectance state, indicia information is subtly viewable by a person viewing said reflective element of said mirror assembly.
