polymer dispersed liquid crystal film supplier/PDLC

Switchable Film

Adjustable optical thin film is a kind of wisdom film, the film laminating directly on the glass, repass voltage makes the light penetration and fog film, realized the glass penetration and the double requirements of privacy, even if is not transparent, daylighting is very good, this is the curtain of all cannot achieve, insulation reflection effects of heat and light, make indoor warm in winter and cool in summer, environmental protection and energy saving.The product utilizes the optical properties of liquid crystal to realize the photoelectric function of thin film.At present, this product is widely used in Europe, America and Japan.Hollywood actress, director, business men, multinationals light glass decorative noble building and amusement park to run out of film do magic, car use it as a skylight, villa, Banks, insurance companies, hospitals, hotels, restaurants, store, showroom for cultural relics and museums, churches, command center, etc. Use it as a partition, door, window, ceiling, the store also can use it as a transparent back projection screen to attract customers.

Dimming film is a new type of electronic light control product. The electrically controlled intelligent dimming film device is a mixture of liquid crystal/polymer material injected between two transparent conductive films. Under the circumstance of no electric field action, the electrically controlled intelligent control film is in an opaque state.Electrification generates an electromagnetic field, which makes the intermediate polymers orderly and transparent.

The intelligent control film is in an opaque state;When an alternating current is applied, the liquid crystal molecules are arranged in an orderly manner. At this time, the electromodulating film changes from an opaque (OFF) state to a transparent (ON) state.Through the action of electric field, it can realize the fast conversion from open state to off state, from off state to open state
