Flat panel display: improving policies to promote industrial support

“In recent days, I visited a company specializing in light guide plates in Changzhou, Jiangsu. The company is currently the world’s fourth-largest manufacturer of light guide plates, with a monthly capacity of 2,000 tons, and its capacity is still expanding. The world's two largest LCD The panel companies Samsung Electronics and LGD are their customers, and as can be seen from this example, the domestic flat panel companies should not only pay attention to the production of LCD panels, but should also consider the localization of details such as the diaphragm inside the backlight module. Jin Guopan, a member of the Chinese Academy of Engineering and a fellow member of the International Optical Engineering Society, told the China Electronics News reporter.

Since the end of last year, Beijing, Shenzhen, Hefei, Kunshan, Nanjing and other places have successively invested in the establishment of high-generation LCD panel production lines, and industry authorities have expressed concern about the overcapacity of LCD panels in China in the next few years. Because the structure of liquid crystal display technology is quite complex, it involves upstream related materials and devices. If domestic companies make more efforts in the details of the industry chain, this will be beneficial to the healthy development of the flat panel display industry in China.

Recently, the National Development and Reform Commission issued the "Notice on Continuing to Organize the Implementation of the Strategic Industrialization Transformation of the Color TV Industry in 2010" (hereinafter referred to as the "Notice"). The "Notice" clearly stated that enterprises in supporting materials shall be encouraged to upgrade their independent innovation capabilities and achieve the production of key supporting materials in accordance with the needs of panel and module manufacturers, and to develop and develop a new generation of display technology, AM-OLED (Organic Light Emitting Diodes). Industrialization has put forward new requirements. This indicates that China's flat panel display industry will enter a new round of accelerated development.

Included in the strategic emerging industries In accordance with the "2010-2012 flat panel display industry development plan" requirements, the main principles of China's flat panel display industry development is to reasonably control the scale, guide the industrial layout, co-ordinate internal and external development, strengthen independent innovation, and promote industrial support. Improve industrial policies.

Wu Shijing, deputy director of the Department of Electronic Information at the Ministry of Industry and Information Technology, told the China Electronics News that the country will include the flat panel display industry in the strategic emerging industries and will give priority support.

In fact, in 2005 the world's flat panel display industry has entered a period of rapid development, but at that time China did not grasp the opportunities in this industry. “There are two main reasons for this. On the one hand, the performance of companies such as BOE, SVA, and Longteng Optoelectronics has suffered losses, which has caused people to worry about the development of the flat panel display industry; on the other hand, CRT TVs can still be used. There is also a certain market size,” said Sun Zhengmin, secretary general of the Shenzhen Flat Panel Display Industry Association, in an interview with a reporter from China Electronics News.

However, domestic companies later recognized the importance of vigorously developing the flat-panel display industry and actively entered the field of high-generation LCD panel production lines. "BOE, TCL, Longteng, and other domestic companies involved in the field of high-end LCD panels to a certain extent, led to flat-panel display companies in South Korea, Japan and China's Taiwan to accelerate the establishment of LCD panels in China's high-generation factory." China Electronics Video Secretary-General of Trade Association Bai Weimin told reporters of China Electronics News.

However, investment in the establishment of high-generation LCD panel production line has become a trend for a while, there has been a blind start, the next few years may cause the Chinese mainland LCD panel overcapacity situation. According to Jin Guojun’s analysis, due to the obvious effect of high-generation LCD panel projects spurring the development of related industries, investment in factories around the country is a market activity, and lack of unified planning may result in excess capacity.

Recently, the “Notice” issued by the National Development and Reform Commission clearly stipulated the principles for the development of liquid crystal display industry, focusing on color filters, polarizers, liquid crystal materials, driver ICs, wet chemicals, targets, and backlights (including brightening film, Reflective films, etc., determine the direction of development of the liquid crystal display industry from the height of the industrial chain.

Fortunately, at present, China has issued a scale in the development of liquid crystal display supporting industries, such as liquid crystal materials, glass, polarizers, color filters, backlight modules.

Focusing on the industry's cutting-edge technology, Jin Guojun told the "China Electronics News" reporter that the development of flat panel display industry can not be limited to the existing liquid crystal display technology, OLED (organic light-emitting diode) display technology, laser display technology and the display industry-related 3D technology , energy saving and environmental protection technologies, etc., China should be early layout.

OLEDs are seen as the future of the flat panel display industry. It is to see the potential of the OLED industry, many places in China have begun to get involved in OLED technology research and industrialization attempts.

According to statistics, at present, China is engaged in OLED research and development throughout the country, and Jilin, Beijing, Jiangsu, Shanghai, Guangdong, and Sichuan have OLED R&D or production bases. There are more concentrated areas in Sichuan, Jiangsu, and Guangdong.

The "Notice" also pointed out: "Encourage qualified companies to focus on breakthroughs in key new technologies for display technologies such as AMOLED, and gradually develop industrialization capabilities. These include AMOLED's substrate technology, vacuum coating technology, and thin film packaging technology."

However, experts in the development of OLED technology still have little disagreement. Sun Zhengmin, Zhang Bing, Zhang Baizhe all suggested to reporters: "To develop the OLED industry, we must first develop TFT-LCD (thin film field effect transistor liquid crystal)." Experts believe that the current development of the flat panel display industry should focus on TFT-LCD Industrially.

Sun Zhengmin told reporters: “At present, the state supports the development of liquid crystal, plasma, and OLED, of which 80% of the power should be placed in the TFT-LCD industry. From the current technology trend, whether it is electronic paper or OLED, it needs TFT. Technology as a platform. For example, the driving technology of AMOLED is the TFT. To develop AMOLED, we must first develop the TFT technology."

Jin Guolu believes that the current OLED technology must first solve the problem of not being able to make big, but OLED will be the view of the future display technology has not changed.

Zhang Baizhe, an expert in liquid crystal technology at Tsinghua University, said that the so-called industrial substitution is a subversive alternative, such as TFT-LCD instead of CRT; the other is based on the replacement of the original technology, such as OLED can not do without TFT technology. OLED technology reserves are related companies in the LCD industry.

Zhang Bing, chief representative of DisplaySearch China, told the "China Electronics News" reporter that LCD production capacity will be further expanded in recent years; PDP (plasma) will not increase production capacity by 2012; OLED is currently only Sony, LG worldwide Samsung is doing it. From the market trend, the development of TFT-LCD is the current focus.

Coordinating the overall development of the layout In the era of CRT, China has organized and implemented the "Television Specialization in Localization of Color TVs", taking the whole machine and key components as the leader, led the development of related raw materials and equipment, constructed a complete industrial chain, and established China's independent color tube. The color TV industrial system has laid a solid industrial foundation for the glory of domestic color TV sets since the 1990s. "The consolidation of the LCD panel industry in the Mainland will sooner or later, and there will be deeper cooperation between the two sides of the Taiwan Strait in the flat panel display industry." Li Zhaoyao, chairman of AU Optronics, told the "China Electronics News" reporter.

In fact, the key to the next step in China's flat panel display industry lies in how to coordinate the layout. Sun Zhengmin stated that at present, China needs leading enterprises. For example, the State is encouraging the panel companies to establish a test platform for the application of flat panel display materials certification, and to interact with the material companies to test and verify the materials in a real environment, and accelerate the localization of flat panel display materials. In foreign countries, these platforms are companies such as Samsung and LGD. However, in China, none have done a better job.

On the OLED side, Tian Chaoyong, Sichuan Hongvision’s product technology minister, told the “China Electronics News” reporter: “At present, the main problem in the OLED industry in China is that each unit engaged in OLED related industries should be more open-minded. At present, China is engaged in OLED. The industry has spread all over the country, but the country’s resources have not been effectively integrated."

As of December 2009, there are five OLED production line projects that have been built, under construction, and planned in Guangdong, namely the Shanwei Truly small-size OLED production line, Foshan Zhongxian Technology's low-temperature polysilicon AMOLED production line project, Dongguan Hongwei's OLED display demonstration. Production line project, AM (active) OLED photoelectric project of Huizhou Maoqin Optoelectronics Company and OLED production line project of Rainbow in Foshan. In Sichuan, Hongvision is by far the only company in China that has developed AMOLED products and has more than 110 OLED patents. "How to prevent 'one move up' and rationally lay out the flat panel display industry is a problem that needs to be solved at present." Sun Zhengmin said.
