As the 2017 International Smart City Expo is about to open, "smart city" once again becomes the focus of people's attention. In fact, since the first batch of 90 national smart city pilot programs was launched in 2012, China's "smart city" has come a long way. With the development of social economy, the population that cities need to accommodate is also gradually increasing, and the government's demand for the construction of smart cities is growing. This means that smart cities will become a new urban model in the future, and it also indicates that it will create a huge new economic market.

I. What is a smart city?

　　To know whether LED displays can be used in the construction of smart cities, we must first understand what a smart city is. The concept of a smart city is: using information and communication technology to sense, analyze, and integrate key information from various core systems of urban operations, so as to make intelligent responses to various needs, including people's livelihood, environmental protection, public safety, urban services, and industrial and commercial activities.

　　In short, it is the use of information technologies such as satellite positioning, the Internet of Things, cloud computing, and social networks to achieve intelligent management and operation of cities. To illustrate with a simple example, in a smart city, the system can provide more scientific and effective solutions by integrating information from all aspects. Then we can easily find the fastest and least congested commuting routes on our mobile phones; water and electricity supply will be more scientific, and residents will not have to endure staggered water and electricity use; with the use of cameras and police monitoring systems, the safety index of streets will also be greatly improved...

　　Today, with the rapid development of new generation information technologies represented by the Internet of Things, cloud computing, and mobile Internet, the construction of smart cities has become more feasible. With the acceleration of urbanization in China, problems such as urban congestion and resource shortages have become more prominent, and the promotion of smart cities has become more urgent. According to the deployment of relevant ministries and commissions of the state to promote the construction of smart cities, it is expected that by the end of 2017, the number of cities in China that have launched the construction of smart cities and are under construction will exceed 500.

II. Can LED displays seize a place?

　　In the wave of smart cities, can LED displays be used? After understanding the general concept of smart cities, this question becomes self-evident. In the concept of smart cities proposed by China, there are application projects including smart public services, smart city complexes, smart government city comprehensive management and operation platforms, and smart transportation. Among them, LED displays will become the display terminal for various types of information, supporting the operation of smart city systems.

Indoor LED large screens: Display terminals for smart city operation platforms

　　Whether it is traffic and security command systems, or astronomical and geographical monitoring systems, the final monitoring and command departments have a demand for indoor large-screen displays. This is also an inevitable need for smart city visualization, and LED displays are undoubtedly one of the choices for large-screen displays. Compared with traditional large screens such as LCD splicing screens, LED displays have high color saturation, better image display effects, and low light requirements. With the increasing clarity of the latter, their competitiveness in the field of indoor large-screen displays is becoming stronger. Therefore, under the wave of smart city construction, LED displays will shine brightly.

　　In fact, in recent years, with the rise of small-pitch LED displays, more and more government-related departments and units have purchased such indoor LED displays for use as display systems for command and control platforms in areas such as security, government affairs, and transportation. This development trend has undoubtedly played a certain role in promoting the construction of smart cities. In the future, with the further advancement of smart city construction, the demand for indoor LED large screens will be even broader.

LED lamp pole screens: Adding bricks and tiles to smart cities

　　The applications of smart cities are mainly divided into three categories, the first of which is for 2C public customers, providing services for people's livelihood systems such as education, medical care, transportation, and environmental protection. Therefore, in the construction of smart cities, the transmission of information to citizens will also be an important part. In particular, the construction of a smart transportation system may drive the widespread application of LED lamp pole screens.

　　A new type of smart streetlight has emerged, which can automatically adjust the brightness according to the time of day, act as a charging pile, connect to WiFi, charge mobile phones, and even monitor PM2.5 and guide urban traffic flow. Such powerful capabilities not only save energy but also save urban space and serve citizens. With the increase in smart public needs, will such streetlights have public information display and advertising placement functions in the future? The gradual introduction of LED lamp pole screens may be a good answer.

Detailed projects are extensive, and the demand for displays is huge.

　　In addition to indoor large screens, community service information displays, and lamp pole screens, which have a certain demand for LED displays, under the new construction in multiple aspects and fields of smart cities, other more detailed areas will inevitably have a greater demand for LED displays.

　　For example, in the construction of a smart transportation system, faster and more timely guidance on traffic conditions will become a trend, which means that traditional fixed display signs will be replaced to a certain extent, and new information prompts and guide signs will also have a large number of displays. In this process, the demand for LED displays, which already occupy a certain position in the road traffic system, will be even stronger.

　　The promotion of the construction of other systems such as smart parking lots and smart medical care has also highlighted the need for the display of real-time information. In that case, how can LED displays not be used?

　　Currently, in addition to China, countries such as the United States, Europe, Japan, and South Korea are vigorously building smart cities. Therefore, the wave of smart cities shows a global trend. Its transformation of all aspects of society not only facilitates people's lives and business activities but will also bring a new round of market growth. As the world's largest producer of LED displays, China's LED display industry is bound to have a bright future in the construction of smart cities.
