PET polyester film-'optical film'-technical knowledge
PET polyester film-'optical film' Source: protective film factory direct release time: 2019-05-05 click: 1421 to change the optical characteristics of the surface of the optical part and the one or more layers of film plated on the surface of the optical part is the optics PET film. Optical PET film is divided into reflective film, antireflection film, filter film, optical protective film, polarizing film, spectroscopic film and phase film according to application. The first four are commonly used. 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. Films, protective films in touch panels, and films for flexible displays, etc. Among the upstream raw materials of liquid crystal panels, optical films are used in backlight modules, polarizers, and liquid crystal materials. The demand trend of optical films in liquid crystal display panels Liquid crystal display is the current mainstream flat panel display technology, which is widely used in fields such as LCD TVs, notebook computers, monitors, and mobile phones. In the entire TFT-LCD production process, the total area required for optical films is about 15-20 times that of the panel, and the cost is about 15-20% of that of the LCD panel. China is becoming the world's largest producer of flat panel display equipment. At the same time, the explosive growth of the domestic touch screen industry has prompted a rapid increase in the demand for optical films. Optical films have become one of the most important strategic raw materials at the front end of the optoelectronic industry chain. The monitoring data of the demand for optical films in color TV shows that the output of China's color TV increased from 76.73 million in 2004 to 139.7081 million in 2012. In 2013, the output of China's color TV exceeded 140 million, a year-on-year increase of 0.4%. The PET film market is huge, polyva film provides you with professional services and products, you are welcome to buy.
