Patent Images
1. A vehicular rearview assembly having a front and front peripheral region, the assembly comprising:
- a first substrate includinga first surface corresponding to the front;
a second surface; and
a first transparent electrically conductive electrode layer carried on the second surface;
a second substrate includinga third surface; and
a fourth surface; and
an at least partially reflective stack of materials carried on at least a portion of at least one of the third surface and the fourth surface;
a perimeter seal between the first substrate and second substrate;
wherein the first substrate, second substrate, and the perimeter seal define a cavity;
an electro-optic medium disposed in the cavity between the first substrate and the second substrate and bounded by the perimeter seal; and
a ring of spectral filter material disposed circumferentially at a periphery area of the first substrate on at least one of the first surface and the second surface, wherein a diffuse reflectance at the periphery area of the first substrate is greater than a specular reflectance by at least about 3 L* units.
