Self-adhesive PDLC smart film is an improved product from the non-adhesive PDLC film, by adding a self-cling adhesive layer on the rear side of the normal PDLC film, then the film has a self-adhesive function. The film can stick directly to existing glass, which provides a simple and cost-effective alternative to retrofit the existing glass into switchable PDLC glass. When power is on it becomes transparent, when power is off it becomes opaque.
Working principle
Smart PDLC film(Polymer Dispersed Liquid Crystal Film) is an interlayer film in the middle of Switchable PDLC Glass. When there is no electric field(Power off), the Liquid Crystal Molecules inside are scattered irregularly, so the incident light will disperse and can not pass through, and the PDLC film appears Opaque(Milky White). When there is an electric field(Power on), the Liquid Crystal Molecules are arranged in an orderly manner, so the incident light passes through freely, and the PDLC film appears Transparent(Clear state).
Supply Mode
We supply both customized cut-to-sheet size smart film and standard roll-size smart film to meet different clients’ requirements.
