LED display industry standards need to be standardized

Wu Xiaogang, general manager of Shenzhen Qipu Optoelectronics Co., believes that the standardization of LED display industry can not only help enterprises to achieve large-scale production more quickly, but also unify the collaborative production of the industry, which is the need of enterprises and the blessing of the industry.

Promote standardized background

According to the statistics of LED display applications of China Optical Optoelectronics Industry Association, in 2012 China's LED display application market reached 25.3 billion yuan, achieving steady growth, and the growth rate was relatively flat. Compared with the rapid growth of a few years ago, the LED display industry has begun to gradually mature and stable. Coupled with the influence of the state's restrictions on luxury and thrift, the display market has undergone new changes and trends. .

The new trend changes the industrial structure. The development trend of China's LED industry can be analyzed from the following three points: First, product technology deepening and product diversification. The technical basis and level of China's LED display industry should be said to be quite advanced. The main products and key technologies can be consistent with the international advanced level of the same industry, but the process level is relatively backward, in product standardization, system design and reliability. There are obvious gaps with foreign countries in terms of manufacturing processes, testing and testing methods. The second is the standardization of conventional products and the specialization of application products in specific fields. Among the conventional LED display products, standardized display devices and control systems will be more widely adopted. Integrated LED display products will occupy a major position in the industry. The specialized division of production of standardized LED display products and market technical services will be More obvious. The third is the rational division of labor within the industry and the formation of a new industrial structure. With the development of technology and market, China's LED display industry will gradually improve and have a reasonable division of labor in the adjustment, forming a new industrial structure. In the LED display industry, the enterprise groups within the industry will be properly classified, and a technology-developing enterprise based on key control system technology research and development will be gradually formed. Product-oriented enterprises based on large-scale and standardized production will be promoted by market application. The main technical service-oriented enterprises, professional application-oriented enterprises that meet the needs of professional markets.

LED display production and LED illuminator production technologies have been widely used in various fields of social life. The development of the semiconductor lighting industry has brought a good opportunity to the LED display industry. Therefore, the LED display market has a wide application space, especially The development of conventional display screens has become the backbone of the industry. Among the conventional LED display products, standardized display devices and control systems will be more widely adopted. Integrated LED display products will occupy a major position in the industry. The specialized division of production of standardized LED display products and market technical services will be More obvious. In the professional application field, LED display products meet the needs of professional applications, the level of specialization will continue to improve, and specialized products combined with application requirements will expand into new products and new application fields that form LED displays, such as the large-scale urban lighting project. Area LED display, LED display of stadiums, LED display in traffic field, etc. There are indications that standardized production is already an inevitable stage of industrial development under the new situation.

At present, the conditions for standardized production have also matured. With the emergence of several large-scale enterprises and dozens of medium-sized manufacturers in the LED display industry, the basic pattern of display manufacturing technology and division of labor has formed, and standardized production of LED displays has become possible.

China's LED display standardization status

The standardization and revision of the LED display industry in China has been in existence for a long time. In particular, the increase of independent research and development and innovation patents in China has made the formulation of various standards urgent.

The LED display industry standard can be traced back to the 1998 electronic information industry standard "General Specification for LED Display". Subsequently, the industry associations and organizations such as the LED Display Application Branch of China Optical Optoelectronics Industry Association actively organized the revision, improvement and implementation of the standards of the information industry industry standard "LED display general specification" and "LED display test method". At the same time, many companies are actively participating in LED device, semiconductor lighting and other industry application standards.

At present, LED display standards, such as "LED display general specifications" and "LED display test methods", "the stadium display LED display specifications" and other electronic industry standards have been promulgated. In addition, related application areas have also developed relevant application standards, such as the Ministry of Railways' "Guidelines for LED Information Display by Passengers, the "Variable Information Board Standard for Expressways" of the Ministry of Communications, and the Standard for Variable Speed ​​Limits for Expressways. The Ministry of Public Security's "Urban Traffic Guidance Information Board Standards" and so on. The release and implementation of these standards constitute the basic framework of the standardization system for LED displays in China, and play a major role in regulating market development and promoting industrial upgrading.

Despite this, the LED display industry is advancing with each passing day, especially in the emerging areas of discovery and development, as well as intensified competition and low margins. The pace of industry standard setting is far less than the speed of industrial development. For many LED display manufacturers, all face standard problems. For example, in the production of display screens, the display screen belongs to the nature of engineering and product categories. Secondly, the various manufacturers of series spacing are different, which causes difficulties in later maintenance and interchange; in addition, in the LED display module, due to The difference in the LEDs produced by the upstream package and the inconsistency of the parameters of each module lamp make it difficult to carry out the standard even in the minimum display function unit. Due to the mixed parameters of the display screen, the standard is not uniform enough to make the internal management confusion and social wealth waste.

Therefore, the formulation and implementation of industry standards is not only the work of industry associations, but also the concerns of major related companies. At present, a considerable number of enterprises have taken the lead and started to participate in the formulation and improvement of various standards. Among them, Qipu Optoelectronics is also actively promoting the promotion of standards.

Qipu Optoelectronics is committed to standardization operations

As we all know, LED display products include many components and accessories, and the standardization of each link is conducive to the standardized production of the whole machine. The cabinet is a key component that occupies an important position on the LED display and affects the standardized production of the LED display. The standardized production of the cabinet is undoubtedly an important part of the standardization of the LED display.

Shenzhen Qipuguang is an active promoter of the standardization of LED display cabinets. As early as 2011, Qipu Optoelectronics developed and manufactured the Black King Kong box module, and constantly put forward its own ideas in the standardization work of the box. At the national LED display application technology exchange meeting held in Changsha in September 2013, the black gold standardization process proposed by Qipu Optoelectronics received the response from the participants. According to Wu Xiaogang, general manager of Qipu Optoelectronics, Black King Kong is the culmination of Qipuguang's annual summary in the production of LED displays. It brings many benefits to the company in the continuous improvement and improvement of generalization, serialization and combination.
