Glass has excellent light transmission and provides a wide view, from daily glassware to optoelectronic technology glass, the user of glass date back to thousands of years. The development of coating technology has greatly changed or enhanced the original properties of glass, resulting in more new applications. 

Low-E glass can greatly reduce heat loss that due to radiation from indoors to outdoors by depositing a variety of thin film layers on glass substrates, while improving comfort with excellent thermal and optical properties, which can be used in more spaces, such as large-are architectural projects. 

Electro-chromic glass, with depositing ITO, oxide and phase-change material on the glass substrate, realizing the intelligent control of glass by adjusting the light transmittance according to the environmental conditions, and can be used in automotive glass, etc.
