Abstract
An inventive rearview assembly for a vehicle may comprise a mirror element and a display including a light management subassembly. The subassembly may comprise an LCD placed behind a transflective layer of the mirror element. Despite a low transmittance through the transflective layer, the inventive display is capable of generating a viewable display image having an intensity of at least 250 cd/m2 and up to 3500 cd/m2. The display includes a novel backlighting subassembly and novel optical components including a magnifying system, a depolarizer, a reflector, and a reflective polarizer. The display may be configured to display an image having edges contoured to correspond to the edges of the mirror element.
