Abstract

The invention discloses a car rearview mirror with color-changing performance and a manufacturing method thereof, which improves the structure and manufacturing process of an electrochromic device so that it has the characteristic of self-supply, and its color-changing response time is short , the service life is prolonged, the freezing resistance is good, and the self-color can be changed according to the light intensity, so that the user can have a clear observation field, and the method of the invention is simple and easy to operate, and easy to industrialized production.

Description

technical field [0001] The invention belongs to the field of automobiles, and more specifically relates to an automobile rearview mirror with color-changing performance and a manufacturing method thereof. Background technique [0002] In conventional technology, car rearview mirrors generally do not have automatic color changing function, and are generally located on the left and right sides of the car head, as well as in front of the car interior, and the mirror reflection principle is generally used to check the road conditions behind the car. [0003] However, the stronger light irradiation of the rear car will make the driver blind for a short time, which is easy to cause traffic accidents. Contents of the invention [0004] Based on the technical problems existing in the background technology, the present invention aims at the problems existing in the background technology. It improves the structure and manufacturing process of the electrochromic device, so that it ha...
