  • Detail

China's flat panel display is blocked: materials such as substrate glass restrict the development of flat panel display industry. At present, the development of domestic flat panel display industry is changing with each passing day. As an emerging industry at the national strategic level, it has been carefully supported and developed by the state and the government. Under the background of national economic structure adjustment, the upgrading and transformation of the flat panel display industry is imperative. In recent years, the production lines of high-generation LCD panels put into production, under construction and proposed to be built in the mainland have been in full swing. The self-sufficiency rate of large-size LCD panels has been continuously improved, breaking the monopoly of foreign countries in the field of mid-range LCD panels in the flat panel display industry and gaining the right to speak. However, the domestic flat panel display industry needs to further develop, or even leap forward, and the localization of LCD panel supporting industries is not optimistic, Upstream equipment and materials seriously restrict the further development of domestic flat panel display equipment industry that can replace imported products

first, the midstream has made a breakthrough, and the self-sufficiency rate has increased year by year.

according to digitimesresearch, in 2016, the production capacity of large-size TFT-LCD panels in the mainland accounted for 21% of the global production capacity, while the production capacity of small and medium-sized TFT-LCD panels accounted for 35.7%. The overall production capacity of TFT-LCD panels in the world will rapidly increase from 6.5% in 2011 to 23.7% in 2016. In line with South Korea The two places in Taiwan have formed the production focus required by the indicators of three key industrialization projects of new chemical materials and key technologies

analyze the development of large-scale TFT-LCD production capacity in the mainland. With the successive completion and production of domestic high-generation LCD panel lines, the large-scale LCD panel production capacity by 2016 can meet the 60% self-sufficiency rate of TV panels required by mainland color TV brand manufacturers. At that time, the production capacity of the 6th generation LCD panel line and below in the mainland will mainly focus on how small and medium-sized liquid crystal panels can take a share of China's economic development in the next five years, and be applied to smart, tablet computers and other mobile terminal devices. Many 8.5 advanced generation LCD panel lines mainly produce large-size LCD panels to supply TV, display and other equipment

II. The field of upstream equipment and materials must be enriched and improved.

it has been 10 years since BOE built the 5th generation line in Beijing. In the past 10 years, China has built a large-scale TFT-LCD industry almost from scratch. At present, 21 production lines have been built and are under construction in China, including 4 generation 4.5 lines, 4 generation 5 lines, 2 generation 5 lines, 3 generation 6 lines and 8 generation 8.5 lines, with a total investment of RMB 200billion and an annual production capacity of 50million square meters. The products cover the display screens of various display terminals, such as, tablet computers, notebook computers, desktop computers, televisions, etc., and the direct or indirect annual output value of which reaches hundreds of billions of yuan

such a huge investment has greatly stimulated the upstream demand of the industrial chain, and driven the development of upstream industries such as substrate glass, liquid crystal materials, polarizer, color filter, optical film, touch screen, backlight and other related raw materials, components and related equipment. It is estimated that after 2016, China's TFT-LCD industry will need at least 250 tons of liquid crystal materials, 100million square meters of substrate glass (including glass for color film), 100million square meters of polarizer, 50million square meters of weight, color filter, billions of square meters of optical thin film, hundreds of millions of backlight components and hundreds of millions of driving ICs every year, with a total value of nearly 100 billion yuan

what is the development of local upstream equipment and materials in the face of such huge business opportunities? At present, most of the supporting services are still supported by foreign manufacturers, and the development of domestic upstream equipment and materials lags behind, which seriously restricts the development of the flat panel display industry. At present, no key supporting materials have made a comprehensive breakthrough and formed an enterprise group that can provide mass production products. As one of the strategic emerging industries, the state will continue to support the new display industry. However, only by solving the problems of core technology, scale and development environment can China's LCD supporting industry achieve considerable development

penghongbing, deputy director of the electronic information department of the Ministry of industry and information technology, said that the combined scale of several leading enterprises such as BOE, csot, Tianma, and CLP panda is only a fraction of the scale of some well-known panel enterprises abroad. The core problem is mainly the lack of supporting capacity to support the industry, lagging behind the development of the panel industry

in terms of main key supporting materials, such as glass substrates, liquid crystal materials, polarizers, polarizers, drive ICs, etc., several major suppliers in the world have a very high market share, while TFT equipment, especially the front production line equipment, is almost blank

1. Substrate glass: the actual research and development is still insufficient.

as a basic component of liquid crystal display devices, substrate glass is also a weakness in China's supporting industries. Although this component only accounts for 17% of the total cost of the LCD panel, it is the most delicate and expensive. The transportation cost is very high, and its output directly affects the output of color filters and other components above the 5th generation line. However, China's substrate glass mostly relies on imports, and there are few enterprises actually engaged in the production of substrate glass
