Problems solved by technology

If lecithin is used as a surface treatment for vertical alignment materials, it is used in rearview mirror devices. Because of its ionic structure and hydrophilicity, it is easy to destroy the liquid crystal system and reduce the resistivity of the surrounding liquid crystal materials.
Causes low contrast in optoelectronic characteristics, and significantly shortens service life after frequent circuit driving
Therefore, this type of rearview mirror is not suitable for use on cars

Abstract

A CL-type rear view mirror able to automatically regulate light is composed of LCD, photosensitive device, power supply and casing. Its advantages are low drive voltage, high response speed to electric field, wide visional angle and high contrast.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to a liquid crystal automatic dimming rearview mirror. Background technique [0002] In the modern automobile industry, all components are constantly updated with the advancement of technology, but the rear-view mirror and side-view mirror of the car still use general mirror materials, and the image clarity of the driver's viewing mirror is obviously affected by the intensity of rear light. , it is clearer during the day, and when there is strong light at the rear at night, the light will irritate the driver's eyes through the reflection of the rearview mirror, making people feel dazzling, affecting the driving line of sight, and causing traffic accidents easily. Scientists have done a lot of research and made great progress. For example, they have developed an electrochromic mirror, which belongs to electrochemical display. A layer of electrochromic material is plac...
