Abstract

A mirror having a field emission information display includes a semitransmitting reflecting mirror body for a rear vision mirror installed in the car, a field emission unit, a control unit, and a satellite navigation module. The field emission unit is installed in the semitransmitting reflecting mirror body. The control unit is installed in the semitransmitting reflecting mirror body and is connected with the field emission unit for controlling the field emission unit to display information images. The satellite navigation module is installed in the semitransmitting reflecting mirror body and is connected with the control unit for receiving a satellite signal and transmitting the satellite signal to the control unit. Thereby, the satellite signal is controlled by the control unit so as to be transmitted to the field emission unit. The field emission unit generates an information image area on the surface of the semitransmitting reflecting mirror body.
