When was Smart Glass Invented?
1984 – The Birth of PDLC Technology
Polymer-Dispersed Liquid Crystal (PDLC) technology was first patented by J.L. Fergason in the United States. His invention, based on a micro-emulsion method, allowed glass to switch between transparent and opaque states using an electric current. By 1987, Raychem Corporation secured exclusive patent rights. Early PDLC technology required high voltage, was expensive, and had a limited lifespan of fewer than three years. It had a haze factor of 12%, slow cycling speeds, and was sensitive to temperature variations.

How does Smart Glass work and what is Smart Glass?
Smart Glass is any glass that has Smart Tint installed on the surface of it or sandwiched in between 2 pieces of glass. The original old school smart glass was only available sandwiched in between 2 pieces of glass. This method was soon upgraded to a surface mount Smart Tint version for many important reasons. Here is a list of advantages of Genuine Smart Tint® w/ proprietary nano hard shell scratch resistant coating and proprietary Smart Cling® self adhesive peel-n-stick backing technology that is included with all of our Smart Film®. Genuine Smart Tint has the lowest haze rate of less than 1.5% providing the best performing Smart Film world wide!
Traditional Smart Glass is very expensive to transport, Install and needs to be cycled has the heat build up due to its embedded glass design requires a cool off period. Smart Tint is low voltage, NEC compliant and does not have to be cycled and is a fration of the cost of pre manufactured smart glass and can instantly convert any glass with its application.
Smart Tint applied Smart Glass transitions from transparent to opaque with the flick of a switch when power is applied.
While this may seem like magic, it is simply the interaction of the embedded PDLC or Polymer Dispersed Liquid Crystal technology and low voltage electricity. With power Genuine Smart Tint® Switchable electric Smart Film® turns clear and when the power is removed it turns private. Smart Tint also manufactures the reverse operating technology that Powers OFF Clear and Powers ON Private. Contact a Smart Tint project manager with any question and a free estimate for your project. All Smart Tint films are dimmable as well.
