Mitsubishi Chemical will introduce three high-performance films for foldable organic EL displays.
Mitsubishi said that they are developing transparent polyimide (PI) films that can be used for low-temperature film formation. The film can be supplied to the market at a low price, reducing manufacturing costs.
In addition, Mitsubishi Chemical has also developed PET films and flexible epoxy films that are resistant to bending. According to the performance of the film, the company can apply the front cover of the display, the touch sensor, and the thin film transistor (TFT) substrate to meet the growing demand of the display market.
Relevant information shows that Mitsubishi Chemical is a comprehensive company formed by the merger of Mitsubishi Chemical Corporation and Mitsubishi Petrochemical Co., Ltd. on October 1, 1994. The company provides products through its three main divisions: functional materials and plastic products (including information and electronics, specialty chemicals, pharmaceuticals); petrochemicals; carbon and agricultural products. The company has now developed into 371 subsidiaries, of which 113 are multinational companies with operations in 17 countries.
In recent years, Mitsubishi Chemical is committed to the research and development of thin films related to displays.
It is understood that Mitsubishi Chemical once imitated the moth-eye structure in April last year and developed anti-reflection film (anti-reflection film) products. The width of the new anti-reflection film products will be doubled to 1200mm. . Prior to this, the company’s anti-reflection film products were 600mm wide and were mainly used in small and medium-sized LCD panels such as tablet computers. Into.
In addition, Mitsubishi Chemical Holdings plans to invest about 1.5 billion yen to build a new production line at its existing plant in Wuxi, Jiangsu Province, China. It aims to increase China’s optical film production capacity to 10,000 tons in spring 2019, It will reach twice the previous level, in the hope of consolidating the global leading position of optical film through increasing production.
The product that Mitsubishi Chemical plans to increase production is the release film required for the manufacture of LCD TV parts “polarizing plates”. Without calculation of yield and simple calculation, 10,000 tons is equivalent to about 100 million 60-inch LCD TVs Release film. After 2018, the number of polarizing plate production lines is expected to increase from the current 9 to more than 20, and Mitsubishi Chemical plans to increase production by taking 50% of the release film market in China to market share.
