PDLC Technology
In clear mode an electrical current passes through the PDLC (Polymer Dispersed Liquid Crystal) interlayer which aligns the microscopic crystals along a number of parallel axes, thus allowing vision through the glass.
When the power is off the liquid crystal molecules are randomly oriented scattering light and the our switchable Smart Film becomes opaque (frosted, private).
When the small electrical supply is on, the liquid crystal molecules align and incident light passes through and the our switchable Smart Film instantly clears (transparent)
