PET polyester film - ＂optical film＂

　　One or more layers plated on the surface of an optical component to change the optical properties of the optical parts are optical PET films. The optical PET film is divided into reflective film, antireflective film, filter film, optical protective film, polarizing film, spectrophotometer and phase film according to the application. Commonly used is the first four kinds.

　　Optical grade polyester film with low haze and high light transmittance, high surface finish, thickness tolerance and other excellent optical properties, mainly for high-end liquid crystal display equipment in the diffusion film, bright film, reflective film, anti-static protection Film, touch screen in the protective film and flexible display film and other fields. LCD panel upstream raw materials, optical film in the backlight module, polarizer, liquid crystal materials are used.

　　The demand trend of optical film in liquid crystal display panel

　　LCD display is the current mainstream flat panel display technology, widely used in LCD TVs, laptops, monitors and mobile phones and other fields. In the entire TFT-LCD production process, the total demand for optical film is about 15-20 times the panel, the cost of about 15 to 20% of the LCD panel. China is becoming the world's largest producer of flat panel display equipment, at the same time, the domestic touch-screen industry explosive growth, prompting the rapid increase in the demand for optical film, optical film has become the front of the photoelectric industry chain is one of the most important strategic raw materials.

　　Optical film in the smart phone needs

　　According to the latest release of the "China Mobile market quarterly data monitoring report in the second quarter of 2014" shows that the second quarter of China's mobile phone market (excluding parallel imports and cottage) sales of 11212 million units, growth of 1.46%, an increase of 24.4%. Among them, the smart phone sales of 102.98 million units, accounting for the overall mobile phone market reached 91.9%.

　　Optical film in the Tablet PC needs

　　According to the "first quarter of 2014 China Tablet PC market quarterly monitoring report" data show that the first quarter of 2014, China Tablet PC sales of 502.9 million units, the chain rose 14.1%, an increase of 48%. China's Tablet PC sales in the second quarter of 5.442 million units, the chain rose 8.21%.

　　According to the organization DIGITIMES Research is expected in 2009 - 2015 global LCD technology digital panel shipments compound annual growth rate will reach 22.7% in 2015 reached 3.5 million shipments scale, the demand for optical film is also growing rapidly. According to WitsView data, this year the size of the panel industry will remain 3% -4% growth, the industry's overall profitability will be better than last year.

　　Optical film applications are very broad, in addition to the above areas with the membrane, there are many other market segments, such as consumer electronics shell, home appliances control panel with single hardening film, matte mask, with the demand for consumer electronics And the growth of home appliances and steady growth; LCD TV with AG anti-glare film, anti-peep film, protective paste, etc., as people on the picture quality and safety needs more and more strong, optical film market space is also growing The

　　China BOPET industry is in a high-speed development stage, polyester film as a green, environmentally friendly, sustainable modification of new industrial materials, its application areas followed by national development, the need to continue to expand, high-performance, multi- The development and application of polyester film will not only promote the development of related industries but also make China BOPET industry production mode from large-scale to specialized division of labor development.
