Six requirements for outdoor LED display installation

With the development of science and technology, LED display screens are playing an increasingly important role in advertising, information release and other fields. Outdoor LED display screens, in particular, are widely used because they can provide high-brightness and high-resolution display effects in various harsh environments. However, the installation and maintenance of outdoor LED display screens have their own unique challenges, and strict installation requirements must be followed to ensure their normal operation and long-term stability. The following are six requirements for outdoor LED display screen installation.

Install lightning protection devices

In outdoor environments, LED display screens are susceptible to lightning. Therefore, lightning protection devices must be installed on the display screen and the building where it is located. The main body and casing of the display screen should be well grounded, and the grounding resistance should be less than 3 ohms to ensure that the large current caused by lightning can be discharged in time. Effective lightning protection measures can prevent strong electric and magnetic attacks on the display screen caused by lightning, thereby protecting the safety of the equipment.

Waterproof measures

Outdoor LED display screens must have excellent waterproof performance. The display screen body and its joints with the building must be strictly waterproof and leakproof to ensure that water can be discharged smoothly in case of accumulation. Since the outdoor environment is often exposed to the sun, rain, wind and dust, the display screen may face serious challenges in waterproofing and moisture resistance. Once electronic equipment is wet or damp, it may cause a short circuit or even a fire, causing serious losses. Therefore, waterproof design is the key to ensure the long-term stable operation of the display screen. What is the difference between LED wall and video wall?

Circuit chip selection

Selecting industrial-grade integrated circuit chips suitable for outdoor environments is an important part of ensuring the stable operation of the display screen. The operating temperature range of these chips should be between -40℃ and 80℃ to ensure that the display screen can start and operate normally under extreme weather conditions. Especially in winter, the low temperature environment may affect the startup performance of ordinary chips, so more adaptable industrial-grade chips must be selected. Provide you with LED chips: technology, application and development.

Ventilation and cooling

In order to prevent the display screen from malfunctioning due to overheating, ventilation equipment must be installed for cooling. Usually, an axial fan is installed above the back of the screen to discharge heat and ensure that the internal temperature of the screen is maintained between -10℃ and 40℃. LED display screens generate a lot of heat when working. If the heat dissipation is poor, the integrated circuit may be abnormal or even burn out, causing the display system to fail to work properly.

Choose ultra-high brightness light-emitting diodes

The outdoor ambient light is strong, especially under direct sunlight, and the brightness of the display screen is required to be higher. Therefore, ultra-high brightness light-emitting diodes (LEDs) must be selected to ensure long-distance visibility and increase contrast. Ultra-high brightness LEDs can provide clear display effects under various light conditions, meeting the needs of wide field of view and long-distance audiences. How do LED chips emit light?

Use a new wide-angle tube

The choice of display medium has a direct impact on the display effect. The new wide-angle tube has the advantages of wide viewing angle, pure color, consistent coordination, and a lifespan of more than 100,000 hours. Its outer package adopts a square cylinder with a shielding edge, silicone seal, and non-metallized assembly. It has five protection features: protection against direct sunlight, dust, water, high temperature, and circuit short circuit. This design is not only exquisite and beautiful in appearance, but also effectively improves the durability and reliability of the display.

In summary, the installation of outdoor LED display screens must consider the requirements of lightning protection, waterproofing, moisture-proofing, heat dissipation, and display effects. Only by making full preparations for these details can we ensure that the display screen can operate stably and efficiently in various harsh environments and provide users with high-quality display services.
