Abstract

[목적][purpose]

본 발명은 전방차량 속도 표시장치에 관한 것으로 특히, 차량 룸 미러에 액정소자(LCD)를 장착하여 전방차량의 속도를 디스플레이 해주도록 함으로써, 전방차량이 어느정도의 속도로 주행되는지를 야간이나 또는 새벽에 용이하게 인식토록하여 안전운행을 도모할 수 있도록 한 전방차량 속도 표시장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front vehicle speed display device. In particular, a liquid crystal element (LCD) is mounted on a vehicle room mirror to display the speed of the front vehicle so that the speed at which the front vehicle is running at night or at dawn. The present invention relates to a front vehicle speed display device that can be easily recognized to promote safe driving.
