A cardboard box, a brand, a craft knife, this is a roadside mobile phone booth all the things. Such vendors are almost everywhere in the city, especially in front of mobile phone stores and IT specialty stores. On October 26th, in front of a subway exit booth in Changping District of Beijing, nearly 10 passers asked about the price of the film, among which four citizens purchased mobile phone stickers. Vendors generally recommend a film based on the size of the mobile phone screen provided by the public, and then paste it in less than 5 minutes.
Do not underestimate this small film, it can not only be attached to the surface of digital electronic products such as mobile phones, digital cameras, MP4. Behind it, there is a more huge industry, which is the optical film industry in the ascendant.
“Mobile phone camera film is the terminal industry of optical film, and it is also an extension of optical film products. Its basic material is optical film, and it is widely used in PCs (personal computers), mobile phones, and liquid crystal displays. It is full of us. Every aspect of life has made our life more colorful," said Wu Shengchu, general manager of Shenzhen Lion Optical Material Co., Ltd.
Small-film industrial optical film, composed of thin layered media, and an optical media material that propagates light beams through the interface. Applications began in the 1930s and are now widely used in the fields of optics and optoelectronics to manufacture various kinds of optics. instrument. The application of optical films is everywhere. From the coating of glasses to the liquid crystal displays of mobile phones, computers, and televisions to LED (Light Emitting Diode) lighting, it has become one of the industries with the greatest potential for growth.
Special reports released by Shenyin Wanguo and Southern Securities and Other institutions indicate that the market size of TFT-LCD (thin film field effect transistor) optical films in 2012 will reach US$7.85 billion. The demand for global TFT-LCD (LED) optical films in 2012 is forecasted. Will exceed 400 million square meters, in which the demand for polarizers is close to 250 million square meters, the demand for prismatic membranes is over 80 million square meters, and the demand for diffuser membranes is over 150 million square meters; according to the current product prices, 2012 is expected to be calculated. The global optical film production value is about 7.85 billion U.S. dollars.
Domestic optical film companies will benefit from the rapid rise of the domestic liquid crystal display industry. Since 2009, China has entered a peak investment in large-size LCD (liquid crystal display) panels. It is estimated that there will be as many as 8 LCD production lines for energy production in 2012, and BOE, Sharp, TCL and so on. With the rapid development and expansion of China's panel and terminal products, upstream optical film and other supporting industries will usher in explosive growth opportunities.
Relevant person in charge of Hefei Lekai Technology Industry Co., Ltd. stated that China is becoming the world’s largest producer of flat panel displays. At the same time, the explosive growth of the domestic easy-to-mold decorative materials and touch screen industry has led to the demand for optical films. Rapid increase in volume, optical film has become one of the most important strategic raw materials for the front end of the optoelectronic industry chain.
There is still a gap in technical equipment. Although the optical film industry is in the ascendant and widely viewed, the domestic optical film industry is still in its infancy. The R&D power is weak and scattered. Basic research and optical design and development for optical functional films have not yet been fully appreciated. .
"Compared with Japan, South Korea and other optical thin film countries, China's gap in technology and equipment is still very obvious." Wu Shengchu said that if a production equipment, if used, the general price of more than 10 million yuan, and domestic equipment The price usually only needs 1 million yuan. Compared to imported equipment, domestic equipment can not meet the requirements in terms of accuracy, etc. At present, only middle- and low-grade products can be the main products.
According to industry sources, at present, most of the key raw materials required by China's optical film industry, especially optical grade slicing and optical film special additives, cannot be produced domestically. The main producing areas of these materials are Korea and Japan, and the technical threshold is high. At the same time, the precision coating equipment and technology supported by optical films have not been systematically researched and developed, and the production of high-end optical films still depends on imported equipment. Most domestic optical thin base films and optical functional film manufacturers in the country, due to the lack of production processes and experience in key links, coupled with the differences in raw materials, most of our products can only meet the low-end applications.
Standard start specification quality Wang Yingru, deputy general manager of China Lucky Film Group, once stated that during the “12th Five Year Plan†period, Lekai will invest more than RMB 5 billion in the field of optical film materials, and Lekai will completely transform from photosensitive material companies into Manufacturer of optical films.
As a leading company in the domestic optical film industry, many Chinese companies represented by Lucky have seen the huge market potential of optical films and have entered this field one after another. For example, Kangdexin added nearly 2 billion yuan in September this year to build an optical film industrialization cluster project. It plans to build an optical film demonstration line with a capacity of 40 million square meters per year. The product line includes films for LCD backlight modules, reflecting light. Film, 3D film, LED light film, etc.
Wu Shengchu believes that the influx of many companies has caused the quality of optical film products in China to be uneven. Therefore, it is necessary to formulate corresponding standards and regulate quality.
It is reported that on October 16, 2008, the National Optical Function Film Standardization Technical Committee (Cursor Committee), responsible for the revision of national standards for optical functional film materials, was formally established. "In the past two years, the cursor has reviewed nearly 20 relevant standards, and now it has released nine, seven Chinese and two." A staff member of the cursory committee disclosed.
It is understood that these standards include "Measurement of warpage of optically functional films" and "Determination of UV absorbance of thin films for liquid crystal displays (LCDs)". "China's self-developed standards not only provide the basis for judgments in standardizing quality and testing, but also play a positive role in promoting the industry's rapid, orderly and healthy development by merging the upstream and downstream industrial chains and promoting the development of China's flat-panel industry. The localization of raw materials at the front end of the display industry chain is of great significance," said the staff member.
