Abstract
A video mirror system for a vehicle includes an interior rearview mirror assembly with an electrochromic reflective element having a front portion and a rear portion generally opposite the front portion. The reflective element has an electrochromic medium disposed between a first substrate and a second substrate and has a transflective third-surface mirror reflector that is at least 15 percent transmitting to visible light and that is at least 40 percent reflective to visible light. A video display is disposed to the rear of the reflective element and emits light when actuated that passes through the transflective mirror reflector. The video display is back lit by at least one light source, and the video display is operable to exhibit a display intensity as viewed by the driver of at least about 400 candelas per square meter when the interior rearview mirror assembly is mounted and is viewed in the vehicle.
