The production scale of polarizers in mainland China is relatively small

The rise of the polarization film industry in mainland China has a long way to go. In the current global display panel market, the production capacity of mainland China is expanding rapidly. However, in sharp contrast, the production scale of polarization film, one of the key materials, is relatively small. This article will explore the reasons, impacts, and future development directions of this phenomenon. The importance and market landscape of polarizers. Polarizers are one of the key components of liquid crystal displays (LCDs), which can control the passage or obstruction of light, thereby achieving the display effect of images. With the continuous growth of demand for consumer electronics products such as smartphones, tablets, and televisions, the market demand for polarizers has also skyrocketed. At present, the global polarizer market is mainly occupied by enterprises in Japan, South Korea and Taiwan, China, such as Nitto Electric, Sumitomo Chemical, LG Chem and Qimei Industry. These enterprises have dominated the global market with their technological accumulation and experience advantages. The current situation and challenges of the polarization film industry in mainland China Although China has made significant progress in display panels, there are still many challenges in the upstream material field, especially in the polarization film field. Firstly, the technical threshold is high and requires long-term investment in technological research and development to reach the international advanced level; Secondly, the capital intensive nature of industries results in huge initial investment costs, which is a significant barrier for new entrants; In addition, environmental pressure is also a factor that mainland enterprises must consider when expanding the production capacity of polarizers. The above reasons have led to a relatively small number of polarization film production enterprises in mainland China, and the overall production capacity scale is relatively small. In order to promote the localization process of core materials such as polarizers, the government has introduced a series of policies in recent years to encourage and support the development of related industries. For example, the 2019 Action Plan for the Development of Ultra High Definition Video Industry (2019-2022) mentioned accelerating the research and development of key common technologies for new displays, supporting the production and manufacturing of 4K/8K ultra high definition and flexible foldable displays, and encouraging the construction of polarization film production lines with independent intellectual property rights. The implementation of these policies is expected to provide more opportunities and development space for mainland polarization film production enterprises. In the face of the current situation, the domestic polarizing film industry needs to increase technological innovation, improve product quality and stability, and reduce production costs to enhance competitiveness in the international market. In addition, strengthening cooperation with downstream panel manufacturers and establishing a stable and efficient supply chain system will also help promote the healthy development of the entire industry chain. It is expected that in the coming years, with the maturity of technology and continuous capital investment, the polarization film industry in mainland China will gradually narrow the gap with leading foreign enterprises and win more say in the global market. Conclusion: Although the growth of the polarization film industry in mainland China faces numerous difficulties, its potential cannot be ignored. Driven by both national policies and market demand, we have reason to believe that the polarizing film industry in mainland China will inevitably usher in broader development prospects in the future.
