Recently, provinces such as Xinjiang, Shandong, Henan, Zhejiang, Jiangsu, and Anhui have experienced high temperatures of over 40 ℃, with many places experiencing "sauna days" and "barbecue days", resulting in multiple dangerous incidents. Many LED traffic information screens flicker unpredictably in hot and humid environments, which is a real scene faced by many provinces this summer.

At the same time, Typhoon Danas (tropical storm level), the fourth typhoon of this year, made landfall along the coast of Dongtou District, Wenzhou City, Zhejiang Province at around 21:25 on July 8th (level 9, 23 meters per second, 990 hectopascals).

Under the extreme weather conditions of "ice and fire", LED display products are facing unprecedented challenges, especially outdoor LED displays. Their performance stability and structural reliability are directly related to public information communication, traffic safety, and even the safety of people's lives and property.

High temperature environment can lead to a decrease in the luminous efficiency of LED chips, and the difference in brightness attenuation of different colored LEDs may cause display color cast. Continuous high temperatures can accelerate component aging and reduce overall service life. At the same time, the strong wind brought by typhoon may make the screen bear huge wind pressure load, and rainstorm will lead to the decline of electrical insulation performance and increase the risk of short circuit. The harsh environment of alternating high temperature and high humidity places higher demands on the material performance, structural design, and control system of LED display screens.

The challenges brought by typhoon weather to outdoor LED display products mainly focus on physical damage and moisture infiltration. The enormous wind pressure generated by strong winds may exceed the design capacity of the display screen structure, causing deformation or even overall collapse of the supporting structure. Rainstorm will penetrate into the box from various joints, resulting in short circuit and corrosion of components. The high humidity environment after a typhoon cannot be ignored, as humid air condenses inside the display screen, which may cause circuit board oxidation and mold growth. Salty sea breeze can accelerate the corrosion process of metal components, posing a threat to long-term reliability.

When facing extreme weather conditions such as high temperatures and typhoons, it is necessary to adopt comprehensive response strategies for LED displays to ensure their stable operation and service life in harsh environments

Integrated design and optimization: During the product design phase, extreme weather factors such as high temperatures and typhoons should be taken into consideration for integrated design and optimization. It is particularly important to adopt modular design, which divides and combines the various components of the LED display screen reasonably, making it easy to install and maintain, and improving the overall protection performance and reliability. At the same time, by optimizing the internal circuit design and layout, reducing heat accumulation and electromagnetic interference, the adaptability of LED displays in complex environments is improved.

Intelligent monitoring and remote management: With the help of advanced sensor technology and network communication technology, real-time intelligent monitoring and remote management of LED display screens can be achieved. By installing various sensors such as temperature, humidity, wind speed, and current inside the display screen, real-time operation data of the equipment is collected and transmitted to the remote monitoring center. The monitoring center can detect abnormal situations in a timely manner through data analysis and take corresponding measures. No matter in high temperature or typhoon weather, the brightness, heat dissipation mode and other parameters of the LED display can be remotely adjusted to ensure its normal operation.

Regular maintenance and upgrades: Regular maintenance and upgrades of LED displays are key to extending their lifespan. In addition to daily cleaning and inspection, regular deep maintenance and upkeep should also be carried out based on the equipment's usage and environmental conditions. Conduct comprehensive performance testing and maintenance on LED displays every six months or one year, including replacing aging components, cleaning the cooling system, and inspecting waterproof and lightning protection facilities. Meanwhile, with the continuous advancement of technology, timely software and hardware upgrades should be carried out on the display screen to enhance its performance and reliability.

User training and education: Necessary training and education should be provided to units and operators of LED displays to understand the precautions and emergency response methods for using LED displays in extreme weather conditions. Regularly train personnel on how to adjust the brightness of display screens correctly in hot weather, and how to take protective measures before typhoons arrive. By improving the user's usage and management level, we can reduce equipment damage and malfunctions caused by human factors.

It is worth mentioning that the construction of a standard system plays a crucial role in the development of the LED display industry. Participating in the development of industry standards can clarify performance requirements under extreme weather conditions. Outdoor LED displays are often faced with extreme weather tests such as high temperature, rainstorm, typhoon, etc. in actual use, and these environmental conditions put forward high requirements for the stability and reliability of products. By establishing industry standards, it is possible to clarify the performance indicators that LED displays should possess in extreme weather conditions, such as waterproof rating, windproof strength, high temperature resistance, etc. This not only provides clear production basis for production enterprises, but also guarantees the usage needs of users in various complex environments.

In addition, in the LED display industry, implementing a certification system can encourage companies to pay more attention to product quality and technological innovation, and improve the overall level of their products. At the same time, the certification system also provides consumers with a simple and effective way to identify product quality, guiding the market towards high-quality products and promoting the overall quality improvement of the industry.

In recent years, against the backdrop of intensified climate change, the extreme weather challenges faced by LED displays will continue to exist. Only by building a comprehensive protection system can we ensure stable and reliable operation under various harsh conditions. This requires the collaborative efforts of all links in the industry chain, from material research and development to product design, from production and manufacturing to installation and maintenance, each link needs to consider the impact of extreme weather factors. Through continuous technological innovation and management optimization, LED displays will continuously improve their environmental adaptability and demonstrate stronger resilience in the face of various challenges. This not only relates to the development of the industry itself, but also affects the stable operation of the digital society. Faced with the dual challenges of high temperatures and typhoons, only by taking precautions can we ensure that the display screen can still transmit information clearly and stably in various extreme weather conditions, and play its due social value.
