Guangdong: E-glass substrate

The TFT alkali-free glass substrate project developed by Guangdong Shantou Jingang Glass Technology Co., Ltd. was successful in August 2003 and has applied for a national invention patent. This project fills the domestic gap and is of great significance in reversing the long-term dependence of China's liquid crystal display production lines on foreign glass substrates.
According to reports, TFT alkali-free glass substrates are important components of liquid crystal displays. Flat panel displays require glass with a thickness of 2.8 mm or less. The glass used in liquid crystal displays is an ultra-thin flat glass. The glass components do not contain alkali metals such as lithium, sodium, and potassium, and they are also resistant to thermal expansion, density, and chemical resistance. All are more demanding than those containing alkali glass. Due to high technical barriers and large one-time capital investment, at present, China is still blank in the production of TFT-I base glass substrates. In July 2002, Shantou Jingang Glass Science and Technology Co., Ltd. successfully won the bid for the major scientific and technological projects in Guangdong Province and made full use of the 2 million yuan special fund provided by the Provincial Department of Science and Technology for the expansion of experiments and the purchase of raw materials such as silica sand and borax. Effectively promoted the smooth development of the TFT alkali-free glass substrate project.
