When the power is on, two PET-ITO conductive film functions as planar electrodes, which makes the liquid crystal droplets orderly arranged perpendicular to the film surface, whereby the parallel light passes through the liquid crystal layer without being reflected and refracted . When the power is on, two PET-ITO conductive film functions as planar electrodes, which makes the liquid crystal droplets orderly arranged perpendicular to the film surface, whereby the parallel light passes through the liquid crystal layer without being reflected and refracted . PDLC Film consists of a polymer matrix of liquid crystals enclosed by electrically conductive Indium Tin Oxide-coated PET film. The resulting PDLC Film has wiring attached to a conductive copper strip (bus bar) along the film's edge. Control using GRAFIK Eye 3000 Series Control Units, Lutron Wallbox Controls, Spacer System, or any incandescent dimmer or Class 2 momentary contact raise/lower control. Allows control of 277V loads using a 120V lighting control. Dimming. Smart film has the dimming function that power on- transparent, power off-opaque.
