Introduction
In the fast-paced modern urban life, subway stations, as an important part of urban public transportation, are not only key nodes for people’s daily travel but also important platforms for information dissemination and cultural exchange.
Parmi eux, écrans d'affichage à LED, with their high brightness, high definition, and rich colors, undertake multiple functions in subway stations, such as transmitting real-time information, displaying urban features, and promoting public service advertisements, and become an indispensable visual focus in subway stations. However, with the continuous increase in passenger flow and the complexity of the social environment, subway station LED display screens are also facing the risk of being deliberately destroyed or accidentally damaged.
This not only affects the normal operation order of subway stations but also damages public property and causes inconvenience to passengers’ travel experience. Therefore, how to effectively protect the LED display screen in subway stations from being damaged has become an urgent problem that needs to be solved.
1. Understand the fragility of LED display screens
- Physical structure characteristics
As a high-tech display device, the physical structure of LED display screens is both complex and delicate. It is mainly composed of LED lamp beads, driver circuit boards, heat dissipation systems, housings, and protective screens.
As a light-emitting element, LED lamp beads have a certain impact resistance, but the screen surface is often covered with a layer of transparent protective material. Although this layer of material can prevent direct contact with the lamp beads, it is also fragile and easily scratched or hit by sharp objects, causing rupture.
In addition, the driver circuit board is a key component that controls the on and off of LED lamp beads. Its internal circuit is extremely precise and sensitive to environmental factors such as static electricity and humidity. Once damaged, it will directly affect the normal operation of the display.
- Impact of environmental factors
The impact of the external environment on the LED display cannot be ignored. First, excessive humidity will cause the internal circuit board of the display to become damp, which will cause short circuits or corrosion, seriously affecting its performance and life.
Secondly, temperature changes are also a major challenge. The luminous efficiency of LED lamp beads will decrease in high-temperature environments, and long-term high-temperature operation will accelerate their aging, while low temperatures may cause the display to be difficult to start or display abnormalities. Dust accumulation is also a common problem.
Dust particles in the air will adhere to the surface of the display and the internal heat dissipation system, which will not only affect the display effect but also hinder heat dissipation, causing the display to overheat and be damaged.
- Human factors
Human factors are one of the main causes of damage to LED displays. In public places such as subway stations, where there is a large flow of people and complex personnel, the negligence or deliberate destruction of passengers may cause damage to the display screen.
For example, passengers may accidentally collide with the display screen due to their luggage or backpacks; employees may damage the display screen due to improper operation during cleaning or maintenance; even worse, malicious vandals may deliberately use sharp tools to scratch or hit the display screen to vent their dissatisfaction or create chaos.
These behaviors not only directly damage public property but also seriously affect the normal operation order of the subway station and the travel experience of passengers.
2. Prevention strategy: physical protection
- Installation location and layout
In subway stations, rationally planning the installation location of LED display screens is the first step to prevent them from being damaged. Display screens should be avoided in areas with particularly dense and mobile traffic, such as entrances and exits, stairways, etc., to reduce the risk of accidental collisions by passengers.
At the same time, the field of view and light conditions of the display screen should be taken into account to ensure that it can clearly display information at the installation location without causing visual obstructions or reflections due to angle problems.
In addition, according to the layout characteristics of the subway station, the display screen can be installed in an area with a certain buffer space or isolation zone to further reduce the possibility of damage.
- Protective measures
In order to effectively prevent the LED display from direct impact and damage, appropriate physical barriers should be used for protection. A common practice is to install a protective cover or tempered glass in front of the display.
The protective cover should have sufficient strength and toughness to withstand a certain degree of impact and scratches; at the same time, its design should take into account the need for ventilation and heat dissipation to avoid affecting the normal operation of the display. Tempered glass is known for its high hardness and impact resistance and can effectively prevent scratches and impacts from sharp objects.
When selecting protective materials, their light transmittance, aesthetics, and coordination with the overall decoration style of the subway station should also be considered.
- Inspection et entretien réguliers
Regular inspection and maintenance are key links to ensure the long-term and stable operation of LED display screens. A regular inspection system should be established to conduct a comprehensive inspection of the display screen’s fixtures, protective facilities, and internal circuits.
Focus on whether the display screen’s fixtures are firm and reliable to avoid safety hazards caused by loosening or falling off; at the same time, check whether the protective facilities are intact and replace damaged or aging parts in a timely manner. In addition, the display screen needs to be cleaned and maintained to remove dust and dirt on the surface and maintain its good display effect and heat dissipation performance.
Problems found during the inspection process should be recorded and reported in a timely manner to ensure that the display screen is always in good working condition.
3. Prevention strategy: technical protection

This not only helps to detect and stop potential sabotage in a timely manner but also provides strong support for subsequent investigation and evidence collection.
In addition, the intelligent monitoring system can also be linked with the security management system of the subway station to form a full-scale, multi-level protection network.
- Content security solution
In addition to physical protection, content security is also an important part that cannot be ignored. In order to prevent sabotage incidents caused by disputes over the content of the display screen, AI technology based on image recognition and natural language understanding can be used to automatically detect and filter bad content.
These technologies can analyze the images and text information on the display screen, identify content that may cause controversy or dissatisfaction, and automatically block or replace it.
At the same time, a content review mechanism can also be established to manually review and check the information displayed on the display screen to ensure that its content is healthy, positive, and in line with social morality and legal and regulatory requirements.
- Remote monitoring and control
In order to further improve the protection efficiency and response speed of the LED display screen, a centralized operation and maintenance management platform can be established to achieve remote monitoring and control.
Through this platform, operation and maintenance personnel can view the operating status, playback content, and surrounding environment of the display screen in real-time and remotely control it as needed. Once an abnormal situation is found or an early warning signal is received, the operation and maintenance personnel can immediately take measures to intervene and deal with it, thereby effectively reducing the risk of damage on site.
In addition, remote monitoring and control can also reduce operation and maintenance costs and improve work efficiency, providing strong support for the intelligent management of subway stations.
