Smart LC Film(Liquid Crystal Film) consists of two PET films and one PDLC layer. While voltage is brought to the two PET films, the smart LC film will turn from opaque state to transparent.  
The working principle of smart LC  film is illustrated in below. With the  film is "off", the disordered orientation arrangement of  liquid  crystals  leads  to  the mismatch of micro  refractive  index and cause strong  light  scattering(during which  the  appearance  of  a  smart  film  is  opaque  and  in  ivory white); while proper voltage is added to  the  film, the electric field makes the liquid crystal arrange in order. The micro  refractive  index  in  a  composite material  is widely  distributed. Light  scattering  is hightly 
restrained(during which the film is in transparent state). 
Smart LC  film consist  of  two layers of  ITO film sandwiched with PDLC  layer. Through  the applied power  control, the  smart LC   film  can  quick  change  in  a   state between clear and opaque.    


The smart film/glass can be used as a rear projector and its affection is far greater than projection curtain.  
Places to install: 
Exhibition hall, cinema, business cupboard, underground marketplaces, boardroom, etc. 
Clean Place 
The  smart  glass  can be  used  in  clean  places  like  hospital, dust-free workshop  to  replace  traditional 
curtain, which have function of separation and privacy protection. The smart glass is safety and solid 
and can kill absorbing noises. It has advantage of environment-friendly and dust resistance. 
The smart glass can be used in bathroom, balcony and bedroom. When power on, all the views outside 
the window  can be seen. When power off,  the  light  transmittance  is good and  the daylighting  is not 
affected and can protect privacy better. 
Marketplace and Bank 
The  smart  glass  can  be  used  in  bank,  jewelry  store,  museum,  exhibition  cabinet,  which  can  keep 
transparent when  open  and  can  switch  to  opaque  state  instantly  by  remote  controller  if  unexpected 
situation happens. On  this occasion,  the criminals will  lost  their  targets, ensuring  the user's personal 
and property safety. 
Office and Boardroom 
The  sense  of  space  in  the  office will  be  bad  if  they  are  separated  by  numbers  of  walls  or  frosted 
glasses. But  if use  transparent glass,  the business confidentiality  cannot be protected. The Smart LC 
Glass is designed to solve the above problem. During the leisure time, the smart glass can be switched 
to the full light transmittance state; and during the business meeting, just a click, the negotiation area 
will become opaque instantly.
