Abstract

The invention discloses a single-polarizer liquid crystal dimming automotive rearview mirror. A layered structure of the rearview mirror comprises a front polarizer, a front substrate, a front substrate electrode, a front direct action membrane, a liquid crystal layer, a rear direct action membrane, a rear substrate electrode and a rear substrate with a reflector from front to back in turn, wherein the front substrate electrode and the rear substrate electrode respectively comprise an ion infiltration-preventing SiO2 film and an indium tin oxide (ITO) transparent conductive film; and the product of the birefraction rate of the liquid crystal and the thickness of the liquid crystal layer is more than 0.2 and less than 1.6mu m. Compared with the prior art, the single-polarizer liquid crystal dimming automotive rearview mirror has better dimming effect and temperature characteristic, good reflectivity in a bright state and a dark state, and low cost, and is easy to popularize.

Description

technical field [0001] The invention relates to the technical field of liquid crystal modulators, in particular to a liquid crystal automobile rearview mirror with anti-glare function. Background technique [0002] After long-term improvement and continuous 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 continuously updated and improved with the advancement of technology. [0003] The anti-glare effect of car rearview mirrors has also been continuously improved, and drivers can obtain information about vehicles behind them through the images of the interior rearview mirror and exterior rearview mirror during driving. The clarity of the image in the mirror is directly related to the relative light intensity of the image. For example, in the daytime image, the light intensity of each part is uniform, the imaging source does not emit strong light, and...
