INTERIOR REARVIEW MIRROR ASSEMBLY WITH FULL SCREEN VIDEO DISPLAY
First Claim
1. An interior rearview mirror assembly for a vehicle, said interior rearview mirror assembly comprising:
- a mirror head pivotable about a mirror support;
wherein said mirror support is configured to attach at an interior portion of a vehicle equipped with said interior rearview mirror assembly;
wherein said mirror head comprises a mirror reflective element having a transflective mirror reflector that at least partially reflects light incident thereon and at least partially transmits incident light therethrough;
wherein said mirror reflective element comprises a reflective region defined by said transflective mirror reflector;
a video display device disposed rearward of said mirror reflective element;
a polymer reflector layer disposed between said mirror reflective element and said video display device;
wherein, with said mirror support attached at the interior portion of the equipped vehicle, said video display device is operable to display video images captured by a rearward viewing camera of the equipped vehicle;
wherein, when said video display device is operated to display video images, light emitted by said video display device passes through said polymer reflector layer and said mirror reflective element for viewing of displayed video images by a driver of the equipped vehicle viewing said mirror reflective element; and
wherein said transflective mirror reflector and said polymer reflector layer allow at least 35 percent transmission of visible light emitted by said video display device and reflect at least about 35 percent of visible light incident at a front surface of said mirror reflective element.

Abstract
An interior rearview mirror assembly for a vehicle includes a mirror head having a mirror reflective element with a transflective mirror reflector. A video display device is disposed rearward of the mirror reflective element, and a polymer reflector layer is disposed in front of the video display device. The video display device is operable to display video images captured by a rearward viewing camera of the vehicle. When the video display device is operated to display video images, light emitted by the video display device passes through the polymer reflector layer and the mirror reflective element for viewing of displayed video images by a driver of the vehicle viewing the mirror reflective element. Linearly polarized light emitted by the video display device is circularly polarized as it passes through the polymer reflector layer, such that the displayed video images comprise circularly polarized light.
