The full name of the new infrastructure is new infrastructure construction. It mainly strengthens the construction of 5G base stations, UHV, intercity high-speed railways and urban rail transit, new energy vehicle charging piles, big data centers, artificial intelligence, and industrial Internet. Based on the network, it is an infrastructure system that provides services such as digital transformation, intelligent upgrade, and integration innovation to meet the needs of high-quality development. Among the seven major areas, transportation construction accounts for a relatively large proportion. In other words, the construction of the transportation field will become one of the key directions for the country in the future, and the monitoring display, command and dispatch center, and traffic guidance display closely related to the transportation network will also Followed by the wind. With the smaller and smaller dot pitch of LED display screens, more delicate display, and smarter functions, the application of LED display screens for traffic display will become the general trend.

1. LED display traffic display application market: In the traffic display market, LED displays are mainly used for information display in bus stations, railway stations, airports, high-speed railway stations, bus platforms, port terminal construction and traffic, with their high brightness , High reliability and other characteristics are favored by the traffic department, and can be made into the command and monitoring center display, urban traffic signal lights, highway LED variable information boards, LED variable speed limit signs, traffic guidance LED displays, and variable traffic information signs. Class LED display products, etc. Among them, the fields such as command and monitoring center display, traffic guidance LED display, and highway LED variable information board are the most widely used and mature in large-screen display.

According to statistics, in 2019, the LED display traffic display application market scale was 3.77 billion yuan, a year-on-year growth rate of approximately 15.7%. In the context of the country’s vigorous development of transportation infrastructure construction, the country is targeting the extension of subway lines in first- and second-tier cities. Increased investment in the construction of transportation infrastructure in third- and fourth-tier cities, as well as the further promotion of the construction of smart cities. As an important part of its composition, transportation display is an important part of its composition, and its application requirements will develop toward intelligence and interactivity. The compound growth rate from 2019 to 2023 will reach 14.6%, and the overall trend of steady and gentle growth will be maintained.

　　2. LED display screen application in command and dispatch center: In the huge transportation network of modern traffic, it is necessary to rely on the deployment system as a cooperation to know the road and vehicle conditions, adjust in time, and ensure the smoothness of the road. At present, the main display equipment of the monitoring and deployment system on the market is LED display, DLP and LCD screen. However, compared with LED display, the problem of small size display and obvious seam of DLP and LCD is its biggest defect. DLP, LCD, and LED display screens have poor grayscale, high brightness, and high cost, which are their limitations when used in traffic control centers. However, after years of development for small-pitch LED displays, the application scenarios and technology are relatively mature, and the price has dropped.

This year, under the impact of the epidemic, many small-pitch LED displays in the industry have begun to cut prices. With the further decline in cost prices and the further maturity of the industry chain, the price advantages of DLP and LCD will no longer exist. With high-definition With delicate, seamless splicing and large-size display, the small-pitch LED display will occupy the field of traffic display in the future. Not only that, the traffic command and dispatch center is the rigid demand for traffic monitoring in every county-level city and above. There are 34 provincial-level administrative regions, prefecture-level cities: 334, county-level administrative regions: 2,876, and a total of 3000+ traffic command center markets. Still waiting for the excavation of screen enterprises. In the two sessions that are still in progress, two-seventh of the rail transit construction, as the current domestic smarter traffic dispatch system, will continue to increase with the acceleration of new infrastructure. The use of small-pitch LED displays Demand will also rise accordingly.

3. The demand for traffic guidance and highway LED variable information boards is rising: The main application scenarios of traffic guidance screens and highway LED variable information boards are the first-class highways in the city. Due to the complex and diverse outdoor environment, outdoor traffic display requires more display screens. Clearly display roads, traffic and other related information in poor visibility weather, while having functions such as light control, high protection, lightning protection and other functions are also required to ensure the normal release of information, and it is required to be able to work and operate 24 hours a day Therefore, the LED display traffic display market has higher quality requirements for display products, stability and service life. The GOB technology, a new generation of super-protection technology for the surface of LED displays in my country, can be waterproof, moisture-proof, sun-proof, and bump-proof from the root. It fits the needs of traffic guidance and highway LED variable information boards very well, which is conducive to the increase of LED displays in outdoor traffic. Shows the permeability. With the improvement of LED display awareness, high-brightness outdoor display, and excellent protection performance, more and more roads use traffic guidance screens and highway LED variable information boards as display devices. And the demand for highway LED variable information boards is gradually increasing.

With the advancement of my country's road construction and the increase in the number of roads, my country's market for traffic guidance screens and highway LED variable information boards has also increased. According to statistics from the Ministry of Transport, the total mileage of highways across the country has been increasing since 2010. As of the end of 2019, the total mileage of roads across the country was 5.0125 million kilometers, an increase of 166,000 kilometers over the previous year. The highway density is 52.21 kilometers/100 square kilometers, an increase of 1.73 kilometers/100 square kilometers. As my country’s infrastructure investment and attention have increased, highway construction has also shown a steady growth trend. The highway mileage is 149,600 kilometers, an increase of 7,000 kilometers. The annual increase in the number of roads is also a huge market gap for traffic guidance screens and highway LED variable information boards.

 Of course, the application of LED display in the transportation field is not limited to the above-mentioned fields, but my country's screen companies mainly develop and produce large-size LED displays. In the past with the promotion of smart city policies and the strengthening of the construction of flat roads in my country, the demand for LED displays in the command and dispatch center, traffic guidance screens, and highway LED variable information boards has increased, and this year's new infrastructure strategy is promoted , The application of LED display in the transportation field will take a step forward.
