Smart film



Smart film is a new kind of smart glass technology in which a special film can be directly and easily applied to glass. The film adjusts to light under electric pressure to switch between a transparent and a semi-opaque state. It also meets the double requirements of glass on penetrability and privacy protection - the lighting is good even when it’s not transparent. It also insulates and reflects infared light, making your room warm in winter and cool in summer, and therefore conserves energy. Smart film utilizes the opto-electrical functions of optical film by employing liquid crystal (PDLC) optics.

Technology of Smart Film

Polymer Dispersed Liquid Crystals (PDLCs)

1. When the smart film is off power, the high polymer LC materials in it are in disorder, which makes light be unable to penetrate the film, and now it’s on opaque state.

2. When the smart film is on power, the high polymer LC materials in it are in order, which makes light penetrate the film, and now it’s a transparent film.


Application of Smart Film

Electric curtain

Environmental and energy-saving for green building material. It uses transparent or haze temperature control film, makes the smart film a haze state when the indoor temperature is high, when the light reduces, the smart film is in a translucent state; when the light is weak, the smart film is in a transparent state.

Projection screen

use the projector on the crystal projection screen similar to a TV screen.

Multi-function

  • Combines touch IR and control by voice commands and the product to give customers more choice.
  • Combines full color LED tube
  • Combines laser membrane and many translucent printing membranes.
  • Combines the projector, effect of suspended particulate as transparent state.
  • Combines multiple movies and advertise to appear in transparent glass.
  • Combines with control system; upon all function can be used with smart film.
