Smart PDLC Film Is a new type of electronic light control products, A mixture of polymer dispersed liquid crystals  is sandwiched between the two ITO conductive membranes, which are reticulated and filled with liquid crystal droplets made up of liquid crystals in the voids. The liquid crystal molecules in each liquid crystal droplet are arranged consistently to form a single-axis liquid crystal body, but the optical axes of different liquid crystal droplets are arranged in disarray. ITO Conductive film is a flake surface coated with ITO conductive layer of polyester film, has a conductive effect. When the light passes through the ITO conductive film, along the propagation direction through the mesh polymer, the liquid crystal droplet, the mesh polymer, the liquid crystal droplet and so on, in the absence of the electric field, because the liquid crystal droplet optical axis is arranged in disarray, causes the light to occur in the liquid crystal droplet and the mesh polymer interface rice scattering, thus presents the opaque state Under the action of electric field, because of the ordered arrangement of the optical axis of the liquid crystal droplet, the light can penetrate the interface of the liquid crystal droplet and the mesh polymer, thus presenting a transparent state.

Smart PDLC Film working Principle :

pdlc technology work principle

pdlc technology work principle

When alternating current is achieved, the liquid crystal molecules are arranged in an orderly manner, and the electro-dimming film is converted from an opaque state (off state) to a transparent state (on state). Through the action of electric field, it is possible to realize the rapid conversion between open-state, off-state and open state.

Two Types of Smart PDLC Film :

smart glass

Non adhesive smart film is used for Smart glass lamination. It is laminated between two pieces of Glass,then finished product is switchable smart glass .

adhesive smart film.

Self adhesive smart film is used for existing glass decorative, belongs to renovation projects. It is with self adhesive layer, can paste on glass surface directly, then common glass with switchable function and can be projected .
