Abstract
A vehicle rearview mirror system includes a transflective reflective element, an ambient light sensor that senses ambient light and a glare light sensor that senses glare light. A control circuit establishes a reflectance level of the reflective element, and the control circuit is responsive to light detection by at least one of the ambient light sensor and the glare light sensor. A display element is disposed behind the reflective element and operable to display information through the reflective element and viewable through the mirror reflector of the reflective element by a driver of the vehicle when the display element displays information, and substantially non-viewable by the driver of the vehicle when the display element does not display information. A display intensity control adjusts display intensity responsive to a light detection by at least one of the glare light sensor and the ambient light sensor.
