Smart glass film, also known as switchable film, is a thin layer that can be applied to glass to control its transparency using electricity. It allows the glass to change from clear to opaque instantly, giving privacy whenever needed. This technology works using liquid crystal particles inside the film; when power is supplied, the particles align and the glass becomes transparent, and when the power is turned off, the particles scatter, making the glass look frosted.
It is commonly used in homes, offices, hotels, and hospitals because it provides a modern alternative to curtains or blinds. Along with privacy, it also helps block UV rays and reduce heat, making spaces more energy efficient. Smart glass film can be operated through a simple switch, remote control, or even a mobile app, making it a convenient and advanced solution for smart interiors.
