In the streets and alleys of the city, lamp pole screens are quietly changing the way we get information and perceive the city. From the initial simple light billboard advertisements to the current digital signage with multiple functions, the lamp pole screen has undergone a gorgeous transformation and achieved remarkable breakthrough development.

Early light billboard advertisements, with their bright colors and simple and direct information display, occupied an important position in the field of advertising. Whether it is at the door of a store in a bustling commercial district or around the venue where an event is held, light billboard advertisements can quickly attract people's attention and convey key information. They mostly use LED lamps to form text and patterns, and are powered by mains or batteries to emit colorful light to achieve the effect of publicity and display. It plays an important role in store advertising, outdoor decoration, fan support and other scenes.

However, with the development of the times, the limitations of traditional light billboard advertisements have gradually emerged. Its information display form is relatively single, and the updated content often needs to be manually replaced, which is inefficient and costly. At the same time, in terms of function, it can only achieve basic publicity and display, which is difficult to meet the increasingly diverse market needs and complex urban management needs. In the era of information explosion, this static and passive communication method has gradually failed to capture the attention of the audience, and it cannot match the intelligent development trend of the city.

In order to break through the limitations of traditional light billboard advertising, the lamp pole screen has made drastic innovations at the technical level. In terms of display technology, a higher density LED module is used, such as high-brightness LED lamp beads with a spacing of P3-P10, so that the screen brightness can reach more than 7000cd/㎡, and the display content is still clearly visible even under direct sunlight. At the same time, the introduction of intelligent control system has become the key, with built-in driver IC and communication module, supporting remote control of brightness, content update and fault monitoring, and response delay less than 0.1 seconds. Through the cloud management platform connected by 4G/5G network, the synchronous update of the content of the lamp pole screen in the whole city, energy consumption monitoring and fault warning are realized. The integration of these technologies has transformed the lamp pole screen from a simple display device to an intelligent terminal that can interact in real time and be remotely managed, providing the hardware and software foundation for its transformation to digital signage.

Lamp pole screens are no longer limited to the single function of advertising, but are developing in the direction of multi-functional integration, successfully breaking the circle. In addition to being a carrier for information release, it is used to display real-time traffic guidance, emergency notices, public service advertisements, etc., replacing traditional banners and light boxes, and also integrates a variety of practical functions. In some smart parks and commercial areas, light pole screens are also linked to smart parking systems to display parking space information in real time to alleviate traffic congestion. This "one pole, multiple functions" feature enables led pole screens to be integrated into all aspects of urban life, from a simple advertising media to an important participant in multiple fields such as urban management and information services.

In commercial scenarios, lamp pole screens have become a powerful tool for businesses to attract customers and increase brand exposure. Taking Zhejiang Jinhua Auto City as an example, the lamp pole screens it introduced, with high-definition and high-brightness display effects and double-sided display design, can clearly capture the screen content no matter which direction pedestrians and vehicles pass by. Information such as new car releases, promotional activities, and test drive appointments in the car city are dynamically displayed through led pole screens, greatly improving the efficiency of information dissemination. Merchants can also apply to place advertisements on light pole screens on their own, combine with the Checheng big data platform, analyze consumer behavior data, conduct precise time period and regional targeted placement, optimize advertising content and placement strategies, and effectively improve marketing results.

In terms of urban management, lamp pole screens also play an important role. On the main roads of some cities, light pole screens are connected to the traffic management system to display road conditions, traffic congestion conditions and emergency warnings in real time, guiding citizens to plan their travel routes reasonably. At the same time, as part of urban emergency management, in the event of emergencies such as severe weather and public health events, the light pole screen can quickly switch to an emergency notification interface to convey important information and response measures to citizens and improve the city's emergency response capabilities. In addition, the led pole screen can also display information such as urban culture and tourist attractions, becoming a window for the promotion of the city's image.

From "light board advertising" to "digital signage", the practice of breaking the circle of light pole screens is a technology-driven and demand-led transformation. It not only changes the pattern of the advertising and media industry, but also contributes to the construction of smart cities. In the future, led pole screens are expected to continue to innovate and develop, play an important role in more fields, and bring more convenience and surprises to people's lives.
