Problems solved by technology

This will not only greatly increase the cost of the rearview mirror, but also because the aluminum dielectric film is not well protected, it will slowly penetrate into the liquid crystal over time, affecting the life of the display

Abstract

The invention discloses a dye liquid crystal anti-glare vehicle rearview mirror, which is formed by overlaying a substrate A and a plane B at intervals according to the pattern of an ITO electrode, and then forms a close box body with peripheral sealing frames. The inner surface of a substrate B is sequentially provided with a SiO2 film, an Al film, a SiO2 film, a transparent conducting film and an orientation layer, and the inner surface of the substrate B is provided with the SiO2 film, the transparent conducting film and the orientation layer. The substrate A and the substrate B are separated by a separation material, and an insulating film in a special structure is designed by using a relief printing method, thereby simplifying manufacturing process. A specific box structure is utilized by utilizing a built-in Al dielectric film mode, without the need of etching the substrate B. When the vehicle rearview mirror is not powered up, the reflectivity of the rearview mirror can be up to about 75%, while the dark-state reflectivity is 10%-13% when powered up. The vehicle rearview mirror has the characteristic of high performance-price ratio and great competitive advantage.

Description

technical field [0001] The invention relates to the technical field of reflective liquid crystal displays, in particular to automobile rearview mirrors with anti-glare functions. Background technique [0002] After nearly a century and a half of development, the car rearview mirror is no longer a simple mirror, but a key device to ensure the driver's safe driving. In the modern automobile industry, all components are constantly updated with the advancement of technology. [0003] The anti-glare effect of the rearview mirror of the car has also been continuously improved, and the driver obtains the information of the rear vehicle through the images of the inner rearview mirror and the outer rearview mirror during driving. The clarity of the image in the mirror is obviously directly related to the relative light intensity of the image. For example, in the daytime image, the light intensity of each part is uniform, and the imaging source does not emit strong light, so the imag...
