The group standard "General Technical Requirements for Asynchronous LED Display Players" ushered in its first public review

On May 6, 2020, the "General Technical Requirements for Asynchronous LED Display Players" group standard, led and organized by the Standards Committee of the LED Display Application Branch of the China Optics and Optoelectronics Industry Association, finally completed the draft for comments after half a year and several revisions of the draft, welcoming the public deliberation of industry experts. For the first time, this group standard review is in an open format, inviting experts in relevant fields of the industry to participate in inquiries and discussions to ensure the professionalism and breadth of standard formulation.


The group standard review meeting for the "General Technical Requirements for Asynchronous LED Display Players" was held online. The conveners are Cai Guangchao, deputy secretary-general of the LED Display Application Branch of the China Optics and Optoelectronics Industry Association (member of the National Standards Committee), Li Nong, leader of the standard expert group for this project, and Zhang Bin, Gu Junwei, Zhang Jiaqing, Zhang Xiaoguang, evaluation experts of the Standards Committee of the LED Display Application Branch of the China Optics and Optoelectronics Industry Association, as well as Leyard and Zhou Ming. Technology, Alto Electronics, Lianjian Optoelectronics, Ledman Optoelectronics, Shanghai Sansi, Xi'an Qingsong, Nanjing Lopu, Changchun Xida, Chitron North, Shendecai and other industry representative companies, including technical representatives of professional companies such as Nova, Lingxingyu, Lingxin Technology and other related technical standards, attended this group bid review meeting. Despite the online communication, the National Standards Committee members, experts and members of the standards group participating in the review, especially the specially invited expert representatives from related fields, were all able to attend the meeting on time, which fully reflected the importance attached to the review of this group's standards. It also highlights the importance and authority of the LED Display Application Branch of the China Optics and Optoelectronics Industry Association as a national association taking the lead in formulating the group logo.


This time the group standard of "General Technical Requirements for Asynchronous LED Display Players" (Draft for Comments) was drafted by Shanghai Yangbang Technology Co., Ltd. and experts from the industry technical group. In order to come up with a group bidding plan with quality that can withstand testing, the drafting party worked creatively, consulted experts from multiple parties and revised the draft several times on the basis of the initial draft. Until this review meeting, the drafting party's CEO and his team gave up their normal vacation and worked overtime to improve the draft for comments.

At the meeting, the convener, Deputy Secretary-General Cai Guangchao, first introduced the basic situation of the China Optics and Optoelectronics Industry Association’s LED Display Application Branch’s work in promoting standards for LED display application groups. In view of the rapid development of LED display applications at home and abroad in recent years, there has been a strong demand for the standardization of asynchronous LED players. The formulation of relevant standards for asynchronous LED display players is increasingly urgent and important for communicating upstream and downstream of the industry chain, and for guiding and promoting the sustainable and healthy development of my country's LED display industry. The introduction of the group's standards will undoubtedly play a more active role in promoting the application and promotion of LED displays.

In my country's standard system, it is divided into national standards, industry standards, local standards, group standards and enterprise standards. As an important part of my country's standard system, group standards are important norms that guide the healthy development of the industry. They are competitive and advanced and are in line with the current market environment of the industry. Building a group standards system is to give full play to the leading advantages of enterprise groups such as initiative and flexibility, so that the standards of LED display screens can keep pace with the times and adapt to the needs of industrial development. It is of great practical significance for standardizing industry operations and enhancing the voice and competitiveness of Chinese enterprises in the international market.

The group standards business of the China Optical and Optoelectronics Industry Association corresponds to the National Standardization Technical Committee for Flat Panel Display Devices (SAC/TC547) and the International Organization for Standardization IEC/TC110. Zhao Ying, technical director of the China Electronics Technology Standardization Institute, is also the chairman of the Group Standardization Committee of the China Optical and Optoelectronics Industry Association.

Since December 26, 2017, the LED Display Application Branch officially obtained the authority to formulate and publish group standards, the association has successively launched the "Surface-mounted Light Emitting Diode Products (SMD) Series Spectrum for Indoor Small Pitch/Mini Full Color LED Displays" and "Asynchronous Grayscale LED The formulation of many group standards such as "General Technical Requirements for Display Controllers (Cards)", "General Technical Specifications for Indoor COB Small Pitch LED Displays", "Energy Efficiency Limits and Energy Efficiency Levels of Outdoor Displays (1)", "Indoor SMD P2.5/P1.9 LED Cloud Screen". On January 14, 2019, the two group standards "Indoor Small Pitch LED Display" and "LED Display Energy Efficiency Test Method" were selected into the 2018 Group Standard Application Demonstration Project of the Ministry of Industry and Information Technology.

Today, various group standards have been released one after another over a period of more than two years. We always adhere to the principles of openness, transparency, and consensus in standard preparation, soliciting opinions, and review. We always follow the spirit of group standards leading the technological progress of the industry, and always put the implementation and promotion of standards and market procurement of standards in an important position.

This group standard review meeting for the "General Technical Requirements for Asynchronous LED Display Players" conducted an open discussion for the entire industry and accepted questions and discussions from experts in various fields of the industry and corporate technical personnel. Hong Zhen, deputy secretary-general of China Optics and Optoelectronics Industry Association and secretary-general of LED Display Application Branch, said that group standards are the competitive demands of the industry. If group standards want to serve enterprises and benefit the industry, they must ensure that the standards are widely representative and authoritative. Inviting business representatives from various fields to participate in the formulation of the group logo and listening to their opinions is to fulfill this goal, so that after the group logo is formulated, it can be truly implemented and truly serve the enterprise and industry.

At this review meeting, participating experts and enterprise technical representatives, as well as all parties involved, conducted repeated and enthusiastic discussions on the draft for comments. Not only did they conduct in-depth communication on the technical details of each standard, they even revised the group standard expression format and other details. During the presentation process of the group standard drafter, Li Nong, the leader of the expert group, repeatedly fed back the opinions put forward by the participants, conducted inquiries based on the opinions of the participants, fully listened to the opinions and suggestions of enterprises in related fields, and did not ignore the speakers because they were not members of the standards group, ensuring the fairness and representativeness of the group standards.

With the participation of participating experts and technical personnel from various enterprises, this review meeting of "General Technical Requirements for Asynchronous LED Display Players" was a complete success. Deputy Secretary-General Cai Guangchao finally summarized the meeting and predicted the time for the next "Indoor Small Pitch/Mini Full Color LED Display Light Emitting Diode Surface Mount Products (SMD) Series Spectrum" (Draft for Comments) group standards seminar, which will be a standard discussion event for the upstream, middle and downstream of the LED display industry.
