| Self-adhesive Smart Switchable Transparent Film For Office is also known as PDLC (Polymer Dispersed Liquid Crystal) film, electronic dimming film, electronic curtain, etc.
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. |

| lt consists of two layers of flexible transparent conductive films (ITO film and PDLC) |
| The film is composed of PET film,ITO film,polymer and liquid crystal molecules. When the film is under off state, the randomly aligned liquid crystal molecules stay along on the walls of capsule, the reflection of liquid crystal molecules and polymer makes light disperses then it is opaque. While electricity supplied, these molecules arrange themselves in a specific direction then parallel light can pass through the film makes it transparent.
