Abstract

A multi-functional vehicle rearview minor that includes a cover, a glass reflecting mirror face, a large sized liquid crystal display device which includes a large sized display screen and a large sized display driver board, wherein the large sized display screen includes a large sized displaying liquid crystal glass and a large sized display device backlight module, wherein the large sized liquid crystal display device is provided with a retention frame and a high obscuration media, wherein a small window with a small sized backlight module and a control circuit is provided. The rearview minor automatically shifts between multiple cameras via signals from vehicle lamps. The RF modules with little power consumption are embedded into the circuits of the rearview minor and the cameras for providing the video shift and information communication of the whole system.

Claims

1. A multi-functional vehicle rearview mirror comprising a cover, a glass reflecting minor face provided in the cover, a large sized liquid crystal display device which includes a large sized display screen and a large sized display driver board, wherein the large sized display screen includes a large sized displaying liquid crystal glass and a large sized display device backlight module, wherein the large sized liquid crystal display device is provided with a retention frame and a high obscuration media at a rear side thereof, wherein a small window is provided on the retention frame and the high obscuration media, wherein the window is provided with a small sized backlight module and a control circuit at a rear side thereof.

2. The multi-functional vehicle rearview mirror according to claim 1, wherein the shape and size of the backlight face of the small sized backlight module is similar to the shape and size of the small window, wherein an illumination face of the small sized module is firmly attached to the rear side of the large sized display device through the small window.
