JNI Smart Glass
Smart glass (or switchable glass) is a glazing whose light transmission properties are altered when voltage, light or heat is applied. Generally, the glass changes from near opaque to transparent, changing from blocking some (or all) wavelengths of light to letting light pass through. Applications of smart glass include privacy glass for conference rooms, light and energy control into commercial and residential buildings, and custom applications. Smart Glass can be applied to buildings, vehicles, and visors. Critical aspects of smart glass include material costs, installation costs, electricity costs and durability, as well as functional features such as the speed of control, possibilities for dimming, and the degree of transparency.
What Is Smart Glass?
JNI SmartGlass uses polymer dispersed liquid crystals (PDLCs) to control light transmission. You are probably familiar with liquid crystals, which are found in many of the products you use every day. Portable computers, calculators, digital clocks and watches all use liquid crystal displays (LCDs). In these displays, electricity is used to change the shape of the liquid crystals to allow light to pass through, thus forming figures and numbers on the display. The technology behind an LCD is similar to the polymer dispersed liquid crystals used in JNI SmartGlass applications. In these windows, the liquid crystals respond to an electrical charge by aligning parallel and letting light through. When the electrical charge is absent, the liquid crystals in the window are randomly oriented. With liquid crystals, the glass is either clear or translucent.
