Until the tang dynasty, the folk were represented by mullion Windows. In the Ming dynasty, the lattice Windows were greatly developed. In the song dynasty, various kinds of mullion Windows were made in various kinds of brick towers, and there were still lattice Windows on the brick tower in the Ming dynasty, which was a lot of examples, which was the predecessor of shutters.

But modern shutters were invented by americans, called John hampson, and patented the invention on August 21, 1841.
The louver  has a louver window. Distinguish from Venetian blinds. Venetian blinds are similar to curtains, with smaller leaves, which can be folded up, which we often use on TV or everyday.

The shutters are generally relatively wide, generally used for indoor and outdoor shading and ventilation. Now more and more people agree that the curtain wall evolved from the shutter. The function of the shutter wall has many advantages, and is very beautiful, generally used in high-rise buildings.
