OCA optical adhesive demand is increasing rapidly
Oct 29, 2018

China is becoming the world's largest producer of flat panel display devices. At the same time, the explosive growth of the domestic touch screen industry has led to a rapid increase in the demand for OCA optical adhesives. OCA optical adhesives have become one of the most important strategic raw materials for the front end of the optoelectronic industry chain.


Optical grade polyester film has excellent optical properties such as low haze and high light transmittance, high surface finish and small thickness tolerance. It is mainly used for diffusion film, brightness enhancement film, reflective film and antistatic protection in high-end liquid crystal display equipment. In the fields of films, protective films in touch screens, and films for flexible displays. Among the raw materials in the upstream of the liquid crystal panel, the OCA optical adhesive is used in the backlight module, the polarizer, and the liquid crystal material.

In the entire TFT-LCD production process, the total required area of the optical film is about 15-20 times that of the panel, and the cost accounts for about 15-20% of the liquid crystal panel. It is predicted that the global demand for TFT-LCD optical films will exceed 400 million square meters in 2012, which is more than 16 billion US dollars. The demand for polarizers is close to 250 million square meters, the demand for prism films exceeds 80 million square meters, the demand for diffusion films exceeds 150 million square meters, and the demand for TV composite optical films is close to 27.5 million square meters. Based on current product prices, the global optical film output in 2012 was approximately $78.5 billion.
