In modern apartments with large windows or suites with glass bathrooms, privacy is a problem. Curtains accumulate dust and spoil the minimalist aesthetic. The cutting-edge engineering solution is called PDLC Glass (Polymer Dispersed Liquid Crystal).

The "Switchable" Technology: This is a laminated film between two panes of glass (or applied over existing glass) containing liquid crystals.

OFF Status (No current): The crystals are disordered, making the glass opaque (frosted white). Total privacy.

ON State (With electric current): The crystals align, and the glass becomes transparent instantly.
