1.Sunshade and heat insulation: the dimming film adopts the combination of two layers of rare earth metal film and one layer of liquid crystal layer. On the basis of the principle similar to the traditional automobile heat insulation film, the main body relies on the 360 ° reflection of liquid particles (liquid spheres with a radius of one thousandth of a millimeter) of liquid crystal as the heat insulation element. When the solar insulation coefficient is as low as 0.4, the heat absorption is less than 28%. In hot summers, compared with traditional insulation films, it can lower the surface of the car seat leather by about 20 ℃. Due to the presence of liquids, expert research has found that what is even more valuable is that insulation films can better reduce heat leakage in winter. Whether it is waves, particles, or radiation, they can reflect more comprehensively, thereby reducing heat leakage.

2. Projection: Due to the high light energy utilization rate of liquid crystals, their projection effect is very good, far exceeding that of ordinary projection screens.

3.Adjustable translucency: The dimming film can be switched between transparent and opaque states by an electric control switch.

4. Safety: It can completely replace explosion-proof film, providing more protection for car glass. Even if the glass is broken, it will not break and fall off, causing harm to passengers inside the car.

5. Privacy protection: The dimming film mainly uses special materials and its intelligent control system, which can adjust the transparency of the glass through the switch at any time during use, thus having a very good privacy protection effect.

6. Sound insulation: Through our experiments, we found that the dimming film also has the function of blocking noise, effectively blocking various types of noise.

7. Energy saving and environmental protection: Due to the thermal insulation and resistance to ultraviolet and infrared rays of the Longsheng dimming film, the usage rate of air conditioning in cars or buildings can be greatly reduced. At the same time, the reflection of ultraviolet rays can prevent aging and wrinkling of car and building interior items. These characteristics give it the function of energy saving and environmental protection. 8. Intelligent operation: Fast response, no matter from opening to closing or from closing to opening, it will not exceed 0.02 seconds, making intelligence more convenient.
