What's the difference between traditional and smart sun visor?

According to the electro-optical characteristics of liquid crystal, the intelligent sun visor adopts the most environmentally-friendly solar energy, and through the unique micro-power design, it realizes the function of automatically controlling the light transmittance of liquid crystal when lighting, so that the liquid crystal screen changes color with the intensity of external sunlight, thus achieving the effect of shading without blocking the line of sight, eliminating the stimulation and harm of external strong light and various harmful rays to drivers and passengers, and playing a comfortable and safe role. In addition, the solar cell-driven analog-to-digital hybrid LCD controller of this product is the first in the world, and it has applied for 13 China patents, of which 9 are national invention patents. Up to now, products such as smart sunglasses driven by solar cells and smart car sunshade invented by smart sunshade are in a leading position in the same industry in the world. ) features, only blocking the sun and not getting in the way, driving comfortably; Automatically change the brightness of the LCD panel according to the intensity of sunlight to reduce visual fatigue; Through feedback control, the amount of light perceived by human eyes can remain basically unchanged. Anti-ultraviolet 99% and most harmful light radiation, effectively protecting eyes; Polarized light can remove glare reflection and play an anti-glare role; Can effectively reduce the strong light emitted by the opposite car when the car meets at night; The solar cell supplies power to the LCD sun visor, without charging, which is safe and environmentally friendly; Wide application range and simple installation; It embodies the incomparable warmth of humanistic care. Today, this technology has been patented in many countries around the world. Domestic * * * applied for 9 invention patents and 4 utility model patents. An automobile intelligent sun visor with adjustable front and rear comprises a hook, a joint plate, a bracket and a color-changing liquid crystal panel in sequence from top to bottom, and is characterized in that the hook is rotationally connected with the joint plate, the joint plate is rotationally or fixedly connected with the bracket, and the bracket clamps the color-changing liquid crystal panel. In addition, the joint plate is rotatably connected with the bracket, and the hook is closed.
