Dimming glass: control method and principle of similarities and differences between dimming glass can then be used by electronic control, temperature control, light control, voltage control and so on various ways to achieve transparent and opaque switch. Living in a variety of conditions, now on the market to achieve mass production of dimming glass, almost all electronic dimming Windows. Electric control principle of the glass easier to understand: when the electrical control products when power is turned off, electronically controlled dimming liquid crystal molecules in the glass appear irregularly scattered, so that light could not score, electronically controlled glass rendered opaque appearance.
