Editing Smart glass (section)

== Applications ==
=== Electric curtain ===
Smart glass can be used for energy-saving heating and cooling in building by controlling the amount of sunlight which passes through a window. A transparent or haze temperature control film makes the smart film enter a haze state when it is sunny and the indoor temperature is high. When it's sunny and the indoor temperature is low, the smart glass enters a transparent state.

=== Privacy ===

* Applied to the glass enclosure of a conference room. When the glass is transparent, one can see into or out of the room, and when it is non-transparent it can be used as a projection screen. 
* Energy-saving function of glass curtain wall

Indoor decoration of residence:
*Lighting cover glass curtain, sunshine house, living room and bathroom compartment. The glass is in a cloudy state when out of use, which protects privacy, and when it turns to transparent, it can allow sunlight.
