Until the Tang Dynasty, people were represented by straight-lattice windows. By the Ming Dynasty, horizontal lattice windows had developed greatly. Various mullion windows were made on brick towers in the Song Dynasty, and horizontal mullion windows were also made on brick towers in the Ming Dynasty. There are many examples, and these are the predecessors of shutters.
The window lattice is nothing more than a few styles, either horizontal or vertical. The horizontal strips are the prototype of the blinds. Strictly speaking, there is one difference between horizontal lattice windows and blinds, that is, horizontal lattice windows are parallel and the gaps are transparent. The louver window lattice is made of oblique lattice, so that it cannot be seen inside and outside in the horizontal direction, and can only be seen when looking at the oblique plane. In ancient times, people made wooden window lattice mainly to achieve the purpose of ventilation and air circulation. After various improvements, modern blinds have integrated many functions and are suitable for various buildings.
But modern blinds were invented by an American named John Hampson and he obtained a patent for the invention on August 21, 1841.
Louvres are generally relatively wide and are generally used for indoor and outdoor shading and ventilation. The louvered curtain wall that more and more people recognize is also evolved from the louver. Louver curtain walls have many functional advantages and are very beautiful. They are generally used in high-rise buildings.
