Dimming glass according to the principle of control means, and the similarities and differences, dimming glass can be borrowed by the electric control, temperature control, electric, pressure control and so on all kinds of ways to realize the transparent and opaque glass state of the switch. Due to various constraints, dimming glass, realize the mass production on the market are almost type electric control dimming glass.
Easy to understand the principle of electrical control dimming glass: turn off the power supply when the electric products, electric control dimming glass inside the liquid crystal molecules will show irregular dispersed state, make the light shows, let electric glass present opaque appearance.
Product definition
Dimming glass is a liquid crystal composite membrane into two layers of glass in the middle, after high temperature and high pressure agglutination mono-assembly of the sandwich structure of new type special photoelectric glass products. Users by controlling the current on and off or not control state of transparent and opaque glass. Not only has all the characteristics of safety glass, glass itself at the same time have control of transparent glass or not privacy protection function, due to the nature of liquid membrane interlayer, dimming glass can also be used as a projection screen, instead of ordinary curtain, high-definition image in a glass. [1]
The working principle of
When turn off the power supply dimming glass, electric control dimming glass inside the liquid crystal molecules will show irregular distribution state, the electronic glass show the appearance of the pervious to light and opaque state; When the dimming glass after electrify, the inside of the liquid crystal molecules present lined up, light can penetrate freely, adjustable light transparent glass instantaneous state at this time. [2]
The control mode
Artificial medallion, artificial light, electric adjustable light, acoustic control medallion, temperature control with medallion, remote control switches, remote network control, can be combined freely according to customer's requirement.
