When no electric current is applied (the OFF state), these liquid crystals are randomly oriented, scattering light and rendering the film opaque and frosted, providing complete privacy. The moment a low-voltage electrical current is activated (the ON state), the liquid crystals instantly align. This alignment allows light to pass through unimpeded, making the film crystal-clear and transparent.

This remarkable transformation happens in milliseconds, offering dynamic control. Beyond instant privacy, LUMEON films are engineered for efficiency. They exhibit low power consumption, typically drawing only 10 watts per square meter when in the transparent (ON) state. Optically, they boast over 96% transparency in the ON state, ensuring ample natural light, and less than 5% light transmission in the OFF state, guaranteeing effective visual block. This advanced engineering ensures not just privacy, but also significant UV protection (blocking up to 99% of harmful rays) and solar heat reduction, contributing to a healthier, more energy-efficient environment.
