Description

Vehicle rear view image and reversing image display system

The present invention relates to a display system, and more particularly to a rear view image and a reverse image display system for a vehicle.

As the range of people's activities expands, the moving distance becomes longer and longer. In order to facilitate the movement, many mobile vehicles are gradually developed. For example, in the case of automobiles, people can arbitrarily move to different places by driving the vehicle, thereby not only increasing the moving speed but also shortening the movement. Time, and with the interior of the vehicle such as seats, multimedia audio and video, etc. to improve the comfort of moving.

However, when driving a vehicle, the driver often encounters many inconveniences. For example, when the driver drives a large truck, a tour bus or a van to move forward, if the driver wants to control the vehicle to turn or change lanes, the driver passes through the driver. Watching the left and right rearview mirrors and the interior rearview mirrors to understand the rear road conditions of the vehicle, but because of the blind spot of the viewing angle, the road condition behind the vehicle cannot be detected, resulting in the vehicle turning or rapidly decelerating to become the rear vehicle chasing.
