ABSTRACT:
The present invention provides a smart mirror apparatus using an LCD panel. The smart mirror of the present invention includes a reflective mirror, which is provided in the vehicle, and an LCD panel, which is placed in a light path between the reflective mirror and eyes of the driver and has one or two polarizing sheets. The smart mirror further includes an incident light detecting unit, which detects both the brightness of the incident light transmitted from the rear to the LCD panel and the brightness around the LCD panel, and calculates a difference value therebetween. The smart mirror further includes a voltage determination unit, which receives the calculated difference value and determines the drive voltage depending on the difference value, and a voltage apply and supply unit which applies the drive voltage, determined by the voltage determination unit, to the LCD panel.
