PDLC film is a kind of polymer dispersed liquid crystal film, also known as electronic dimming curtain film. The development of this film has a history of more than 20 years. PDLC film is the key core material for the production of intelligent dimming glass. With the continuous reduction of cost for more than 20 years, it has become more and more popular, and its application field is more and more extensive. However, due to the high driving voltage, this application is only used in intelligent dimming glass. With the continuous expansion of popularity, PDLC liquid crystal dimming film has begun to develop into intelligent glass film. Therefore, the development of low-voltage driving PDLC film is conducive to the faster and wider development of intelligent glass. Such as: intelligent projection glass, commercial window advertising film, bathroom intelligent glass, intelligent dimming curtain glass, intelligent dimming curtain film, intelligent home glass, . This kind of low voltage PDLC film has the following characteristics: safety, energy saving, low power consumption, intelligent dimming and convenient use, with unlimited application prospects.
