Abstract
A video mirror system for a vehicle includes an interior rearview mirror assembly having an electrochromic reflective element and a video display screen disposed to the rear of the reflective element. The video display screen, when actuated, emits light that passes through a transflective mirror reflector of the reflective element to be visible to a driver of the vehicle viewing the reflective element. The video display screen includes a thin film transistor liquid crystal display element that is back lit by a plurality of white light emitting light emitting diodes. A camera having a field of view rearward of the vehicle is mounted at the rear of the vehicle and, during a reversing maneuver of the vehicle, a video output of the camera is displayed by the video display screen as video images so as to assist the driver in reversing the equipped vehicle.
