Problems solved by technology

[0003] However, due to the existence of the polymer-dispersed liquid crystal layer in the traditional smart dimming film, the clear observation angle is limited to a certain extent, especially the clear line of sight of the left and right rearview mirrors of the car, which is very important for safe driving; and the traditional polymer-dispersed liquid crystal layer They are all reactive UV glue mixed with liquid crystal, without the existence of inert components. The working voltage is generally 48-75V, which is above the safe voltage (36V). For passengers who can easily touch the car film with bare hands, there is a certain degree of safety. Hidden danger

Abstract

The invention discloses an intelligent dimming automobile film, which relates to the technical field of intelligent dimming automobile film preparation. The intelligent dimming automobile film sequentially comprises a wide-viewing-angle optical film layer, a colorless or colored PET conductive film layer, a polymer dispersed liquid crystal layer, a colorless or colored PET conductive film layer, amounting adhesive film layer and a PET release film layer from outside to inside. The intelligent dimming automobile film has the advantages of being good in safety, capable of being used under safevoltage and the like, and can be used for windows and skylights on the two sides of various types of automobiles.

Description

technical field [0001] The invention relates to the technical field of intelligent dimming automobile film preparation, in particular to an intelligent dimming automobile film which has a wide viewing angle, does not affect the clear line of sight of the left and right rearview mirrors of the automobile, and can be used under a safe voltage. Background technique [0002] The smart dimming film is a film that can adjust the state of light passing through. It mainly works between the scattering state and the transparent state. adjust. However, smart dimming films are generally used in modern architectural glass curtain walls, window glass, building interior partitions and other fields. With the rapid development of the automobile market, the production of functional films is becoming more and more diverse and diversified. Applying intelligent dimming film technology to automobile film can control the transparency and atomization state of the entire automobile glass through s...
