China's polarizer industry will usher in explosive rapid growth

The entry of multiple giants has continued to heat up the polarizer industry in mainland China, and the production capacity will continue to grow at a high speed in the next few years.    Strong demand, rapid growth in the mainland    In recent years, almost all of the newly built LCD panel production lines around the world have been concentrated in mainland China. The pace of construction in Japan, South Korea, and Taiwan has been slowed or even stagnated.    Mainland Chinese panel companies, such as BOE, China Star Optoelectronics, CLP Panda, Tianma, etc., are continuing to invest in the construction of new LCD panel lines. In the next two to three years, more than 8 new production lines will start production capacity.   It is estimated that by 2017, China will have more than 28 LCD panel lines of 4.5 and above, and there will be 11 lines of 8.5 generation alone, and several OLED production lines will also be put into production.    Large-scale, high-speed and intensive construction of new production lines will bring greater market space, and the demand for polarizers will also show a higher growth rate. According to statistics from Σintell, the demand for polarizers from panel makers in mainland China in 2014 was approximately 65 million square meters. It is estimated that by 2018, the annual demand for all panel production lines (including LCD and AMOLED production lines) will be As much as 140 million to 180 million square meters, the average annual growth rate is close to 30%.    Get together and settle down nearby supporting facilities    China's position in the global market can be said to be more and more important. The demand for raw materials is also growing rapidly. Coupled with the consideration of tariffs and other aspects, many upstream raw material companies have entered China one after another to support LCD panel companies nearby.    In terms of polarizer industry, Chinese local companies mainly include Shengbo and Sanlipu. Due to the background of state-owned capital, Shengbo's investment plan is relatively conservative, while the three-profit spectrum of another private capital is much more radical.    On December 29, 2013, Sanlipu and Hefei Xinzhan District formally signed a cooperation agreement with a total investment of 2 billion yuan to invest in the construction of a polarizer production base in Hefei Xinzhan District. The project plans to expand 6 wide-format TFT polarizer production lines within 10 years. The first phase of the project is planned to be completed by 2018, with an investment of 1 billion yuan, and three wide-format TFT-type polarizer production lines will be built within four years. By then, the total annual output will reach 35 million square meters.   Kunshan Chimei Materials Polarizer Project was signed in March 2014. The first phase of the project plans to build 2 production lines with an annual output of 12 million square meters of polarizers. The project will eventually plan to build 12 production lines.    The expansion project of LG Chemical's Nanjing plant started in April and is scheduled to be completed in the first half of 2016. The new production line will produce 2300mm wide polarizers, which can be applied to the 8th generation LCD panels. The expansion will increase LG Chemical's Nanjing plant from its current annual production capacity of 40 million square meters to 64 million square meters.    On May 25th, Samsung SDI and Wuxi Municipal Government signed a memorandum of understanding on the establishment of a polarizer factory. Samsung SDI plans to invest more than 200 billion won to build an 8th-generation polarizer factory in Wuxi, with an annual production scale of 30-40 million square meters.   According to the statistical data of Intell Consulting (Σintell), the annual production capacity of polarizers in mainland China in 2014 was about 40 million square meters. It is estimated that by 2018, the annual production capacity will exceed 140 million square meters, which can meet most of the localization needs.   Intensified competition, the profit of national enterprises is worrying    The polarizer industry has a high technical threshold. As early as the 1930s, the United States invented the preparation method of polarizers, and began to realize industrial production in Japan in the 1960s.    Beginning in 1963, SANRITZ began the production of polarizers. Nitto (NITTO) and Sumitomo (SUMITOMO) entered the polarizer industry in 1975 and 1988, respectively.    At the end of the 1980s, South Korea began to produce polarizers. At the end of the 1990s, my country's mainland and Taiwan also joined the polarizer production camp.    The production of polarizer is the crystallization of the development of petrochemical industry and mechanical processing industry, and the preparation of optical grade products is quite difficult. And in the supply of base film, almost all domestic enterprises rely on imports.    Generally speaking, foreig

The domestic polarizer market is gradually expanding, and the development of the domestic polarizer industry will usher in the spring

Technological innovation can fundamentally change the problem Judging from the development of the domestic flat-panel display industry in recent years, with national policy subsidies and the joint efforts of enterprises, the panel industry has developed rapidly, with dozens of production lines. Recently, the world's highest 11-generation line has also settled in China, and the panel production capacity is expected to be global the first. However, for key panel materials and components, it seems that they are not so lucky. Major international display material manufacturers such as Merck of Germany, Asahi Glass of Japan, and Corning of the United States still monopolize most of the domestic material market. For the domestic side, although there are material companies such as Chengzhi Yonghua, Sanlipu, and Dongxu Optoelectronics, it is still difficult to compete with Japanese and Korean companies that have core technologies. Most of them rely on imports. In response, Zhang Jianwei, CEO of Nanjing Guanshi Technology Co., Ltd. said frankly: "In the past two years, in terms of polarizers, although several major domestic companies have made rapid progress, the domestic display material market has gradually entered a stage of rapid growth, but some core materials still rely on With imports, international manufacturers have further increased their investment in the domestic market, making domestic companies still have a low market share and are facing tremendous pressure." In fact, there are two main reasons for the pressure: On the one hand, although the display panel is booming, many material manufacturers focus on output and light quality, and the production process and technology do not meet the requirements, resulting in material product quality that does not meet the standard. Oversupply, panel manufacturers and material manufacturers are under great pressure; on the other hand, limited by the international brand material market, the domestic display material market still has the disadvantage that the core technology is not too hard, and it is difficult to overcome. Due to the late start of the domestic display industry, the core technology is basically in the hands of Japanese, Korean, and Taiwanese companies. Mainland Chinese companies can only conduct research and development through acquisition, cooperation, and technology introduction. In addition, Japanese, Korean and Taiwanese technologies are not easy Therefore, domestic companies are struggling in this display industry, especially in terms of materials. At present, there are relatively few varieties of mid-to-high-end products in the country, which cannot meet the needs of the domestic market. It is urgent to increase scientific research and development efforts. "Therefore, to fundamentally change the problems in the domestic display material market, we can only start with technological optimization, increase investment in display material production technology projects, integrate technological advantages, strive for product technological innovation, and improve product quality and competitiveness." Zhang Jianwei said.   The rise of the panel industry brings opportunities to the material industry    Due to the rapid rise of the panel industry in mainland China, it has brought many development opportunities to the material industry. It is precisely because of this that leading foreign companies such as South Korea's Samsung SDI, LG Chem, and Germany's Merck have built factories in the mainland to grab a share, which will inevitably bring greater pressure to the mainland's leading companies.    In response to this situation, Zhang Jianwei believes that “competition is also a good thing.” "First of all, we can make full use of our strengths and avoid weaknesses, and make full use of the advantages of domestic companies that fully integrate into the local market. To be defeated is not long-term. Only in the face of strong opponents can we improve ourselves faster; in addition, multinational companies do not build factories in China. It represents a complete occupation of the market. Multinational companies have their own advantages, such as capital and channels, but they also have their common problems. Because they are too large, multinational companies have certain limitations in terms of organizational structure, communication and coordination, and execution efficiency." "For example, in terms of modules, domestic companies have a certain low-cost advantage." Due to the low threshold of backlight module technology and low domestic labor costs, coupled with the rapid growth of domestic demand for terminal products such as LCD TVs, The backlight module manufacturing base has gradually shifted to mainland China. According to statistics, in recent years, the output of backlight modules in mainland China has accounted for more than 60%, and China has become the world's largest production area.   "On the other hand, optical films have relatively c
