Recently, according to a survey of relevant data, the mining of public bidding projects on the entire network found that the number of winning bidding projects involving the command center from January to May this year was 7,362, an increase of 2,256 from January to May last year, and the year-on-year growth rate was as high as 44. %, the number of bid-winning projects in the industry has increased significantly. Since the outbreak of the epidemic, the demand for the domestic command and dispatch center system has ushered in a new round of climax. The large-screen system of the dispatch command center has finally ushered in a new leader in market increment once again, and the small-pitch LED display has ushered in market dividends.

 

1. The market dividend of the command and dispatch center appears: the command and dispatch system is divided according to the use occasion, mainly including: electric command and dispatch system, military command and dispatch system, traffic command and dispatch system, emergency command and dispatch system, production dispatch system of industrial enterprises and others. From the perspective of each of its sub-industries, small-pitch LED displays have shown higher growth potential.

 

First of all, from the perspective of the power industry, as the earliest industry in the application of command and dispatch, the current growth rate is slowing down, but with the advancement of smart energy, especially the "Energy Technology Revolution and Innovation Action Plan (2016-2030)" policy promotes grid information and communication Technological reforms and innovations have maintained stable growth for a long time; secondly, the rail transit industry is in a period of rapid growth, and the explosion is accelerating under the tuyere of new infrastructure. The rapid growth of rail transit will also drive the application demand for small-pitch LED displays in the subway command center; The third is the railway industry, which has reached the key node where the stock needs to be updated and transformed and the rapid incremental development is superimposed. On the one hand, with the continuous development of high-speed rail construction, the first batch of high-speed railways will face technological updates and upgrades. The upgrade and transformation projects of the command and dispatch system will also become obvious; the fourth is the national defense industry. Data shows that the national defense budget expenditure in 2020 is 126.805 billion, an increase of 6.6%. In the face of the ever-increasing demand for national defense security, the command and dispatch communication system is used as the military information technology. Important components will maintain rapid growth; finally, from the perspective of other industries, this epidemic will accelerate government emergency construction, such as the Ministry of Emergency Management, the Ministry of Public Security, and the National Health Commission. It is foreseeable that in the post-epidemic era, the country will pay more attention to the construction of visualization based on information networks, the market will pursue higher and higher display effects, and the permanent smart dispatch center of small-pitch LED displays will become the mainstream trend.

 

 
  

2. The advantages of small LED spacing significantly replace DLP/LCD to show the dawn: the command and dispatch market is a high-end market at the top of the pyramid of the large-screen display market. Reliable display technology in terms of stability. However, the splicing gap is still an important factor affecting the visual experience. Due to the physical characteristics of DLP splicing and LCD liquid crystal splicing, there are more or less seams. The development of technology can only shrink the seams, but cannot make them disappear. Projection splicing Although it is physically seamless, there is a fusion zone, which tests the technical strength of the manufacturer and requires regular adjustments to ensure the effect of integration. However, small-pitch LED displays have greater flexibility in splicing due to the characteristics of seamless splicing. At the same time, small-pitch LED displays have better consistency in terms of consistency. Mature point-by-point correction technology makes the adjustment process Simple and easy to maintain. From the composition of the entire industry chain, we can also see that the advantages of small-pitch LED displays are very obvious. Because small-pitch LED displays are in the semiconductor industry and are affected by Moore’s law, they include chips, packaged devices, driver ICs, and control systems. The performance improvement speed of the main materials and the cost reduction speed are very fast, and the small-pitch LED display is currently the only display technology that can achieve localization in the entire upstream, midstream and downstream industry chain. Its cost-effectiveness also makes its competitiveness better. For outstanding.

 

In fact, the industry’s recognition of small-pitch LED displays is almost a one-sided attitude. Both now and in the future, they will continue to erode the DLP/LCD market, and their share in the command and dispatch center market will continue to expand. The manufacturer's strategic route is also very clear, which is to first occupy part of the display product market such as DLP, PDP and LCD. The ultimate goal is to break the dominant position of DLP, PDP and LCD, and reshuffle the entire large-screen market.

 

3. COB/Mini/Micro LED creates infinite possibilities for small spacing: As we all know, the signal that the command and dispatch center needs to display is rich and complex. There are more digital signals than video signals, which imposes almost harsh requirements on products and technologies to deal with huge amounts of data. It requires strong information collection, rapid response, overall coordination, and comprehensive scheduling capabilities. The stability, reliability, durability and easy maintenance of small-pitch LED display products can reduce the human and financial investment in subsequent maintenance. , Has become the key to the selection of the command and control center. But at the same time, the small-pitch LED display is not perfect. There are still many technical shortcomings to be overcome. Enterprises need to continuously increase R&D efforts and investment to innovate.

 

Small-pitch LED displays can now adapt to more and more application scenarios, and the commercialization of new technologies is inseparable from in-depth thinking and exploration of technical routes. In the application scenarios of the command and dispatch center, it cannot be bypassed. It is the heat dissipation problem of the product. Now the mature application of COB technology has led to new breakthroughs in small-pitch LED display technology. Considering the heat dissipation advantages brought by COB technology, the command and dispatch center makes full use of COB small-pitch technology to promote product heat dissipation and other aspects. In addition to the stability advantages, it can achieve a series of unique "performance effects". Even in the future, we can enjoy, Micro LED technology applied to the small-pitch LED display in the command and dispatch center can create an intelligent processing of huge data, display performance, contrast, color indicators, energy-saving levels, etc. far beyond the existing The "perfect masterpiece" of the product. In short, from in-line, surface mount, to COB technology means smaller pitch and higher resolution. This evolutionary process is the progress process of small-pitch LED displays, and more and more developments For the higher-end application market, the development of the command and dispatch center market is also one of the application scenarios developed during its development. Of course, to achieve generational upgrades for small-pitch LED displays, manufacturers need to continue to innovate process technology.

 

All in all, in the generational progress of small-pitch LED displays, the trend of increasing process difficulty level by level has increased the industry threshold, prevented more meaningless price competitors, increased the industry concentration, and made the core enterprises of the industry "compete." Advantages have been significantly strengthened, and more useful products have been created. It can be seen that the “cake” in the high-end indoor display field of the command and dispatch center is not for everyone. The small-pitch LED display is accompanied by continuous technological innovation and To make progress, market participants must be able to grasp the general trends and laws of the industry’s progress, and have advanced strategic vision and pioneering spirit. Any "passive defense" who attempts to rely on temporary technical and market advantages to stand still will only be knocked to the ground.
