Patent ID: 8614847

Claim:
A rearview assembly having a front and comprising: a electrochromic (EC) mirror element, the mirror element including: a first substrate having a first surface corresponding to the front, a second surface opposite to the first surface, and a rounded edge configured to improve durability of the first substrate, the second substrate having a ring of substantially opaque filter material disposed circumferentially around the perimeter of the second surface; a second substrate having third and fourth surfaces and an edge surface, the second substrate being smaller than the first substrate and disposed in a parallel and spaced-apart relationship with respect to the first substrate such that a perimeter of the second substrate is concealed behind the first substrate, the second and third surfaces defining a gap therebetween; and an EC medium in said gap; at least one auxiliary device behind the EC mirror element adapted to deliver light through the EC mirror element towards the front; electronic circuitry operably cooperated with the EC mirror element and configured to control an operation of the at least one auxiliary device; and a user interface (UI) configured to activate said electronic circuitry.
