Window Electronic 5mm Switchable Transparent Film
Electronic Window Film Switchable Transparent Film
Product Description:
STF (Switchable Transparent Film) is also known as PDLC (Polymer Dispersed Liquid Crystal) film,
electronic dimming film, electronic curtain, etc.
It is based on film technology. The rod-shaped polymer liquid crystalls mixing with prepolymer stick
to transparent conductive base material, so that it simultaneously possesses charateristics of liquild
and crystal. When powering off, polymer comes to the atomization of disorder.
With polymer powering on, it is orderly arranged along with the direction of the electric field,
which enables the film to have transmittance of the light.
By controling the electric switch, It can be converted between transparent and opaque state.
