In the just concluded Beijing Winter Olympics, athletes felt the charm of the Winter Olympics supported by technological innovation and the scientific and technological power behind the Winter Olympics. The realization of the vision of "science and technology Winter Olympics" is inseparable from the collaborative innovation of scientific and technological forces in Beijing and Hebei. According to long Fenjie, director of the science and Technology Department of Hebei Province, Hebei Province has formulated and implemented the action plan for wisdom worship of science and technology Winter Olympics, set up special projects for science and technology Winter Olympics, supported more than 100 projects, and 46 project achievements ensured the operation of the games. Hebei enterprises and Hebei technology have played an indispensable role in the splendor of this winter Olympic Games.
new display dazzling
The new display and integrated circuit, known as "one screen and one core", have an important strategic position in the high-end manufacturing industry. China has long faced the problem of "lack of core and less screen", both of which are large importers of goods. However, in this winter Olympic Games, the new display technology represented by LED is very eye-catching and refreshing - behind this is the efforts of Hebei photoelectric display enterprises.
With the help of excellent LED display technology, the ground of more than 10000 square meters in the center of the bird's nest is sometimes like holy and clear ice and sometimes turns into soft and white snow tracks; The dreamy ice cube, ice waterfall, ice crystal five rings and the "snowflake" shaped main torch platform are also full of LED technology. Behind these display products are many Chinese display enterprises such as BOE, Leyard Optoelectronic Co.Ltd(300296) , Unilumin Group Co.Ltd(300232) . Among them, BOE is the leader of China's display industry. It has entered Hebei for more than ten years and has become the core enterprise of Gu'an new display industry base.
The traditional LED ground screen has the problems of large picture particles, low color definition, dull picture and so on. In order to perfectly realize the creativity of the opening and closing ceremony director group, BOE adopts multiple 8K + resolution picture fusion technology, which can carry out pixel level optical correction for each display picture, and can present ultra-high-definition and gorgeous pictures with 100000:1 contrast, 3840hz refresh rate and 29900x15096 resolution.
At the end of last year, BOE released its technology brand α- Mled, which integrates miniled and microled related technologies, represents the new glass based LED display system and solution created by BOE. Related products are based on glass backplane active drive technology, which can bring the ultimate image quality to various scenes such as business display, conference, performance, sports event, E-sports and so on.
The rapid development of the industry is inseparable from the guidance of policies and the joint efforts of upstream and downstream enterprises. In 2018, the three-year action plan for the development of strategic emerging industries in Hebei Province was released, which listed the new display as a major science and technology special project, clearly proposed to expand and strengthen the new display industry, and prospectively focused on strengthening the chain, In particular, it points out that it supports Dongxu group to "overcome the key technologies of glass substrate equipment and promote the process of equipment localization" - this policy has laid a foundation for the rapid development of new display industry in recent years from the upstream of the industrial chain.
strengthen the chain and stabilize the foundation of Dongxu upstream
Founded in Shijiazhuang, Dongxu group is the main supplier of BOE glass substrates and other raw materials. The company has been rooted in the upper reaches of the industrial chain for 25 years and formed industrial clusters with BOE and other downstream enterprises in Hebei, Anhui, Fujian and Sichuan. Now it has developed into a leading enterprise in the localization of core materials in China's new display industry.
Glass substrate belongs to high-end electronic glass. It is the core raw material in the upstream of the display industry. It used to be highly dependent on imports, which restricts the stability of the supply chain of China's new display industry. In 2010, Dongxu group broke the international technology monopoly from the source of this core display material and successfully independently developed a full set of LCD glass substrate production technology: it not only reduced the production cost of downstream enterprises, but also ensured the supply chain security of China's display industry. Relevant technologies won the first prize of 2018 National Science and technology progress award.
In recent years, Dongxu group has continuously innovated around the glass substrate, won the "China Patent Gold Award" twice, and took the lead in mass production of LTPS glass substrate for high-end liquid crystal display, OLED carrier board for new flexible display industry and cover glass for high-end mobile phone and vehicle display in China, Related products can also be used for high-definition led and miniled used in the opening and closing ceremonies of the Winter Olympic Games.
It is worth mentioning that miniled is regarded as a new generation of display technology, and BOE and other Chinese front-line display manufacturers are making efforts here. Glass substrate can replace PCB as the backplane of miniled, which plays a strategic supporting role in promoting the development of miniled industry.
The "14th five year plan" of Hebei Province clearly requires that we fight for key core technologies and "overcome a number of" neck "technologies in the fields of energy storage, hydrogen energy, new display and modern communication", "Expand and strengthen the new display industry, accelerate the research and development of high-end LCD panels, flexible panels and other technologies, and support the cluster development of core supporting industries such as new display materials and optical films." At present, Dongxu group's products fully cover the mainstream industry direction of new display. As China's leading glass substrate manufacturer, the fourth largest glass substrate manufacturer in the world and the third largest cover glass manufacturer in the world, Dongxu group will continue to promote the steady development of China's new display industry at the upstream of the industrial chain.
innovative development supports "science and technology Winter Olympics "
In 2017, the national key R & D plan set up a key special project of "science and technology Winter Olympics". Facing the actual needs of the Beijing Winter Olympic Games, Hebei Province has also done a lot of work based on the deployment of scientific research tasks around the five sectors of competition, competition, viewing, safety and demonstration, which has given more space for local comprehensive innovative enterprises such as Dongxu group.
It is understood that in recent years, the company has actively responded to the national policy of ensuring supply chain security and double carbon goals, continuously improved its independent innovation ability, seized the commanding height of the industry, and developed into a comprehensive industrial group integrating semiconductor photoelectric display materials, high-end equipment manufacturing, environmental protection and new energy, new energy vehicles, cutting-edge new materials and other industries.
Dongxu group's listed company Shanghai Challenge Textile Co.Ltd(002486) is the fabric supplier of uniforms for staff, technical officials and volunteers of the Winter Olympic Games. At the same time, it also provides warm knitted fabrics for long sleeved sweaters of the International Olympic Organizing Committee, the Chinese delegation and the national team.
The warmth retention rate of the company's fleece fabric is 30% - 50% higher than that of similar products, and solves the difficulties such as printing stains, unstable pattern and determining the cutting position of printing, which fully meets the extremely strict requirements of Winter Olympic clothing for printing; In addition, Shanghai Challenge Textile Co.Ltd(002486) recycled yarn is also used in the development of fabrics.
"Green Olympics" ranks first in the concept of "four Olympics" of Beijing Winter Olympics. It has created 12 world-class Zhangbei flexible DC power grid test and demonstration projects, provided a Chinese scheme to solve the world-class problems of large-scale development and utilization of new energy, and ensured that 100% of all venues in the history of the Olympic Games use green power for the first time. In Zhangbei, the listed company Tunghsu Azure Renewable Energy Co.Ltd(000040) of Dongxu group completed and put into operation 80mW photovoltaic power station in 2017, and the annual photovoltaic power generation can reduce carbon dioxide by about 109700 tons.
During the 14th Five Year Plan period, Hebei Province will build a green and clean energy production and supply system, accelerate the construction of a clean energy base in northern Hebei, and promote the construction of Zhangjiakou into a national renewable energy demonstration zone and a hydrogen energy demonstration city. Tunghsu Azure Renewable Energy Co.Ltd(000040) has a professional new energy power generation operation and maintenance management team and new energy post market service capacity. In addition to photovoltaic power plants, it can also provide a number of services for wind power projects, including preliminary planning, wind power EPC Construction and wind farm operation and maintenance. At present, the company operates and maintains a 200MW wind power plant locally.
Zhangjiakou is mountainous and cold in winter, which provides a place for hydrogen fuel cell buses. According to statistics, there are more than 1000 hydrogen fuel cell buses in the event transportation service vehicles of this winter Olympic Games. Among them, all the Winter Olympic guarantee vehicles in the core area of Zhangjiakou competition area adopt hydrogen fuel cell buses. This winter, two models of Shenlong bus under Dongxu group are also running here.
Based on the new generation of domestic electric stacks with small volume and high power density, Shenlong bus has strong power and can cope with complex conditions such as mountains; At low temperature, it can be started and stored within 30 minutes under zero and full hydrogen; Through hydrogen and electricity safety comprehensive management, interlock control technology, can network control and other technologies, Shenlong bus realizes the intellectualization of the whole vehicle and ensures the safety.
Wan Gang, vice chairman of the CPPCC National Committee and chairman of the China Association for science and technology, once said that promoting the application of hydrogen fuel cells in the field of commercial vehicles is of great significance to achieve carbon peak and carbon neutralization. Shenlong bus has an early layout in this field. It started relevant technical research as early as 2006 and launched its first sample car that year; The current products can cover 8-12m models and realize batch operation in Beijing, Shanghai, Zhangjiakou and other places. The company also has the production qualification of fuel cell truck.
