Abstract

A rearview assembly for a vehicle includes a mirror element having a partially reflective, partially transmissive coating, and a video display positioned behind the mirror element such that a display image is viewable through the partially reflective, partially transmissive coating. The video display may have an output intensity such that the viewable display image has an intensity of at least 250 cd/m². The rearview assembly may include a housing having an opening with curved edges. The video display may be positioned in the housing, and the video display may generate a display image that extends along and abuts at least a portion of the curved edges of the housing.
