adjustable glass
Society / Technology

The molecules of liquid crystals change direction depending on the surrounding temperature, electric field, and magnetic field, causing optical changes in areas such as color and transparency to occur. With adjustable glass, a thin layer of liquid crystals is placed between two sheets of glass, allowing a person to freely change the permeability of the light entering the room, thus creating the effect of having blinds in front of the glass. In addition to liquid crystals, other substances such as oxidized tungsten are also used.
