Abstract
A display mirror assembly includes a reflective mirror element having a semitransparent mirror reflector coated onto a light-transmitting substrate. Visible light transmission through the reflective mirror element is at least 3 percent and visible light reflectance by the reflective mirror element is at least 40 percent for visible light incident upon the front side of the reflective mirror element. The reflective mirror element does not exhibit substantial spectral selectivity in its reflectance of visible light incident upon its front side. A display device is disposed to the rear of the reflective mirror element and configured so that light emitted by the display device passes through the semitransparent mirror reflector to be viewed by a viewer viewing from the front. When electrically powered, a display luminance of at least about 60 foot lamberts as measured with said display device placed behind, and emitting light through, the reflective element is achieved.
