PNLC Smart Film, also known as Reverse Smart Film, is a functional PDLC Film made by coating liquid crystal polymer between two layers of flexible ITO conductive film using polymer dispersed liquid crystal technology. The Switchable Glass Film can control the order of liquid crystal molecules through voltage, thereby controlling the transparency of the product. When powered on, the liquid crystal molecules are arranged in disorder under the action of the electric field, and parallel light cannot pass through. At this time, the dimming film is in an opaque state. When the power is off, the liquid crystal molecules are arranged in order under the guidance of the phase matching layer, so that parallel light can pass through. At this time, the PDLC Smart  Film is transparent.
