Patent ID: 8274729

Claim:
A mirror system for use in a vehicular rearview assembly equipped with a light source configured to generate light that is transmitted from within the rearview assembly through said mirror system to a field of view (FOV) outside the assembly, the generated light having a generated spectrum, the mirror system comprising an electrochromic (EC) element, the EC-element including: a first substantially transparent substrate having first and second surfaces, the second surface including a transparent electrode carried thereon, the first substrate corresponding to an outside portion of said assembly; a second substrate having third and fourth surfaces, the second and first substrates being mutually secured in a parallel and space-apart relationship thereby defining a gap between the second and third surfaces, the third surface having a spectrally-selective transflective thin-film stack carried thereon, said spectrally-selective transflective stack having a multi-band transmission spectrum; a seal sealably bonding the second and third surfaces, wherein said spectrally-selective transflective stack is extended beyond the seal towards a perimeter of the second substrate and is configured to make the seal visible from the fourth surface; and an electrochromic medium inside said gap, wherein said mirror system is characterized by a C* value not exceeding 20, as measured in light produced by a standard D 65 illuminant and reflected by said mirror system.
