On March 2, the second phase production line of TAC (cellulose triacetate) film for LCD and the third production line of solar cell back film invested by lucky group started construction in the company headquarters. After the two projects are put into operation, they will break the monopoly of foreign countries on the important raw material market of China's flat panel display and photovoltaic industry.
TAC thin film is an important raw material for making the core component of LCD - polarizer. At present, domestic high-end product manufacturing technology is monopolized by foreign enterprises. Lekai group increased R & D investment on the basis of the original TAC membrane production line, produced high-end TAC membrane and passed the application performance test. The market places high hopes on Lekai's products. After the completion of the project, the domestic TAC film will gradually replace the imported medium and high-grade optical TAC film, so as to reduce the operation cost of China's flat panel display industry.
At present, all kinds of new flat panel display devices led by LCD (liquid crystal display) have developed rapidly, especially thin film transistor liquid crystal display (TFT-LCD) has become the mainstream development direction of new thin display technology, and it is also the core force for the growth of electronic information industry in the next 20 years. Domestic polarizers are in a state of serious shortage of supply and basically rely on imports. The raw material of high-end optical TAC film also depends on imports. At present, lucky has a certain share in the domestic TN / STN (twisted nematic / super twisted nematic) polarizer market, and has made some progress in the research and development of TAC film for TFT polarizer.
Compared with the existing TAC membrane production line in the first phase, many process technologies of the second phase production line have been improved. Based on the production of medium and high-end products, the project is expected to break the foreign monopoly and further improve Lekai's position in the LCD industry chain to meet the development needs of China's flat panel display industry.
At the same time, the construction of the third production line of solar cell back film will produce important materials for solar cell modules, which are used for solar photovoltaic panel packaging, mainly serving the photovoltaic industry in China. At present, TPT (poly (ethylene terephthalate) and TPE (poly (ethylene terephthalate), ethylene vinyl acetate and poly (ethylene fluoride)) are the common back films of solar cells in the market, and the back films with multi-layer pet (poly (ethylene terephthalate) structure in Japan. Lekai solar cell back film has independent intellectual property rights, and its cost performance is better than that of foreign similar products, and is gradually breaking the market monopoly of foreign companies.
