Teardown: Gentex GENK3345S Rear View Mirror

14 March 2018
The following is an overview of a teardown analysis conducted by IHS Benchmarking.

The Rear Camera Display uses LCD technology integrated into a Gentex auto-dimming mirror that works with a video camera mounted at the rear of the vehicle to provide a view directly behind the vehicle while backing up. When the vehicle is shifted into "reverse", a display appears automatically through the auto-dimming mirror's reflective surface. The display disappears when the vehicle is shifted into any other gear, a capability that is made possible utilizing Gentex's "transflective" coating and lighting techniques, which result in a bright, high-resolution color image.
