- a first substrate comprising;
a first surface; and
a second surface;
a second substrate comprising;
a third surface; and
a fourth surface,wherein the first substrate and the second substrate are configured to be held in a parallel spaced apart relationship and sealed around a perimeter of the first and second substrates;
a transflective coating positioned on at least one of the first and second surfaces of the first substrate;
an antireflective electrode positioned on at least one of the second and third surfaces;
an antireflection coating positioned on the fourth surface; and
an electrochromic medium positioned between the second surface of the first substrate and the third surface of the second substrate,wherein the electro-optic assembly is configured to reflect an image from a projector of the heads up display system of the vehicle.

Abstract
An electro-optic assembly configured to be operably connected to a heads up display system of a vehicle is provided that includes a first substrate with a first surface, a second surface, and a second substrate with a third surface and a fourth surface. The first substrate and the second substrate are configured to be held in a parallel spaced apart relationship and sealed around a perimeter of the first and second substrates. An antireflection coating is positioned on the third surface of the second partially reflective, partially transmissive substrate. A transflective coating is positioned on at least one of the first and second surfaces and an electrochromic medium is positioned between the second surface of the first substrate and the third surface of the second substrate. The electro-optic assembly is configured to reflect an image from a projector of the heads up display system of the vehicle.
