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.
Structure of Switchable Transparent Film:
The picture shows the principle diagram of the STF.
The swichable liquid crystal transparent film is also called an electronically controlled smart PDLC flm.
lt consists of two layers of flexible transparent conductive films (ITO film and PDLC).
Available color options:
Principle of Polymer Dispersed Liquid Crystal Film:
By controlng the electic field, It is switchable between the transparent and opaque (atomized) state.
