Nippon Kayaku Co., Ltd.'s subsidiary POLATECHNO will expand into automotive applications through its main LCD polarizer business. POLATECHNO said that the company will accelerate the sales growth of the automotive LCD market by expanding the application fields of the highly durable iodine-based polarizer "JET" and the dye-based polarizer "GHC" with high contrast and strong durability.
With the increase in the number of panels and the expansion of the area, the market for automotive displays continues to grow. Many Japanese companies have invested in R & D and production of vehicle displays.
In July 2018, Dexials invested in the research and development of related film products for automotive displays, and developed a sheet-shaped thermal conductive film, which is mainly used in head-up displays and sensor camera modules. It is understood that the sales of Diruihe's reflective films for automotive displays are growing at a rate of 50% per year. Di Ruihe said that the company's current reflective film can provide thin-film materials for 50 types of vehicle display screens of auto manufacturers in Asia, Europe and the United States.
In addition, the AIST also developed a low-reflection and high-durability wire grid polarizer in June this year.
According to the AIST, the wire grid polarizers they developed are more durable, more transparent, and more reflective than ordinary polarizers on the market, and the reflectivity of the polarizer is reduced to one-tenth of the polarizers on the market. The degree of polarization is 99% or more and the reflectance is ≤5%. The company said that the polarizer has heat resistance, humidity resistance, anti-glare and abrasion resistance, and will be suitable for use in the field of glasses and the automotive industry.
