on June 1, 2020, and the standard was officially implemented on June 15, 2020. As the standard review expert, academician Jiang Fengyi of the Chinese Academy of Sciences believes that the standard is the "No. 1 standard" in the field of mini led, and the standard chip size of mini LED display is defined as 50-200 m. Let micro led, mini led and led have strict boundaries, which is conducive to the scientific and healthy development of the industry.It is reported that the group standard of general technical specification for mini led commercial display screen was proposed by Shenzhen lighting and display engineering industry association, and led 56 units, including Alto, TCL Huaxing, abison, Jufei, Lehman, Zhouming, lyade, Konka, Skyworth, Hisense, qianglijucai, Huacan, mulinson, Guoxing, Hongli, Samsung, OSRAM, Kerui and xinyasheng, According to the technical development of the global display screen industry and in combination with the characteristics of China's Mini LED industry chain enterprises, it took half a year, through extensive research and 15 repeated modifications and discussions.As the world's first group standard for mini led commercial display, the group standard general technical specification for mini led commercial display specifies 11 key terms such as mini led, mini LED display module and mini led commercial display.
It has three important meaningsAt the group standard reading meeting of general technical specification for mini led commercial display screen held on May 27, 2020, academician Jiang Fengyi of Chinese Academy of Sciences made a detailed comment on the standard, mainly including:First, promote the development of the industry. Academician Jiang Fengyi believes that the release of the group standard of mini led commercial display screen is of great significance and plays an important role in the development of new technologies, new products and new formats of display screen at home and abroad. "The standard makes uniform provisions on terms, so that the industry has more common topics and more common technical specifications, which is not only conducive to technological innovation, but also conducive to product manufacturing and application promotion, which is of great practical significance."
Second, enhance the international competitiveness of Chinese led enterprises. Display technology is an important strategic investment in the field of science and technology. At present, Chinese manufacturers are gradually encroaching on the world's high-tech display technology market, ranking first in the LCD field, steadily catching up in the OLED field, and have the ability to compete with traditional display powers in the mini / micro LED technology field. The release of the group standard "general technical specification for mini led commercial display screen" is expected to become the technical basis for independent innovation of mini LED display screen products "and help enterprises use" more innovative technologies to support the sustainable development of the industry and further enhance the international competitiveness of the industry ".
Third, effectively distinguish micro led, mini led and led. At present, the mini LED industry chain is growing, and products and technologies are constantly innovating. However, "prosperity" is an illusion. Behind it, the real situation is disorder. Under the same product name, there are a variety of technical identification standards. Consumers are miserable and practitioners are tired of distinguishing. According to the group standard of general technical specification for mini led commercial display screen, the chip size of mini LED is between 50-200 M, which makes micro led, mini led and led have strict boundaries, which is conducive to the scientific and healthy development of the industry.
Speech by academician Jiang FengyiLeaders, experts and entrepreneurs:Good morning, everyone! I'm glad to participate in today's standard reading meeting. This standard is led by Shenzhen lighting and display engineering industry association and participated by more than 50 units such as Alto and TCL Huaxing. The standard will be read out soon!
After reading this technical specification, I deeply feel that it is a very meaningful thing and plays an important role in promoting the development of new technologies, new products and new formats of display screens at home and abroad. The standard makes uniform provisions on terms, so that the industry has more common topics and more common technical specifications, which is not only conducive to technological innovation, but also conducive to product manufacturing and application promotion. It is of great practical significance. It can be said that this is gratifying.The introduction of this standard has become the technical basis for independent innovation of mini LED display products. It is hoped that more innovative technologies will support the sustainable development of the industry and further enhance the international competitiveness of the industry.
I noticed that there is an upper limit and a lower limit for the size range of mini led in this technical specification. After communication, it is agreed to limit it to 50 m. The upper limit is set at 200 m. I think this range is more appropriate. The lower limit is 50 m. If it is lower than the lower limit, it will enter the category of micro LED; If above the upper limit 200 m. So it is actually the chip size of the traditional display screen. Defined at 50 m-200 m. I think it is relatively reasonable.
As a No. 1 standard, the current definition is relatively fair. With the progress of technology and the development of industry, this technical specification will be further modified, improved and supplemented in the future, which will enter a new standard, namely standard 2. It is hoped that the downstream display manufacturers will cooperate with the device packaging plants in the midstream and the chip manufacturers in the upstream, make collaborative innovation in the upstream, midstream and downstream, constantly launch new technologies and products, explore new applications, and make new and greater contributions to the development of the industry. I wish the conference a complete success. Thank you.
