PDLC Switchable Frosted Glass with Switchable Privacy Glass Film
What is Smart Glass
Smart glass, also known as switchable glass, is a type of glass that possesses light transmission properties that can be altered by applying light, heat or voltage to it. The more common types of smart glass make use of a small amount of electricity to transform between transparent and translucent. Electronically tintable glass when activated will change the tint of the glass by using electricity to control microscopic particles within it. This enables the glass to effectively block out some or all wavelengths of light. With just the touch of a button or a gesture or flip of a switch or your phone, you can instantly change the tint of smart glass to keep out harsh sunlight as well as outside heat. Switchable windows are also effective at blocking out infrared and UV rays, thus making your interior safer, cooler and more enjoyable.
How does switchable privacy glass work
Through the application of an electrical current the properties of the glass change turning it from opaque to clear in less than 0.01 seconds. This transformation to opaque and back again can be triggered from a range of wall switches, remote controls, movement sensors, light sensors or timers, depending on each customer’s individual needs. Numerous variations of privacy switchable glass can be supplied including colour tinted, fire rated, double glazed, curved and shaped privacy glass.
The original ON/OFF switchable smart glass is a laminated glass panel with a polymer dispersed liquid crystal interlayer film (PDLC). It offers instant privacy at the flick of a switch by changing its state from transparent to opaque and vice versa through a small electrical current.
Once activated, Electric Glass turns transparent for as long as the transformer is running. When the electrical current stops, the electric smart glass instantly returns to an opaque state.
