In extreme weather, outdoor digital signage needs to maintain normal function from multiple aspects. Here are some key strategies and measures:

 1. Use efficient heat dissipation system

Outdoor digital signage is prone to malfunction due to overheating in high temperature environments, so an efficient heat dissipation system is the key feature decide the reliable of outdoor digital displays. Common heat dissipation methods include:

- Air conditioning heat dissipation (ACU): Suitable for scenarios that need to run for a long time in high temperature environments, which can effectively control the internal temperature and keep the equipment running stably.

- Heat exchange heat dissipation (HEU): Dissipate internal heat to the outside through a heat ex-changer, suitable for environments with higher temperatures.

- Forced air cooling (FAU): Use fans to force air flow to take away the heat generated by the equipment. This method is low-cost and easy to do maintenance.

Taking the Shenzhen Outdoor Convenient Electronic Information Display Project as an example, the summer temperature in the area can reach up to 40 degrees Celsius. By adopting a realistic design of heat dissipation gaps, stable operation at high temperatures is ensured.

 2. Improve the waterproof and dust proof level

Rainwater, dust, etc. in outdoor environments will seriously affect the service life and performance of equipment. Therefore, it is necessary to have a high protection level, such as IP65 or higher, to ensure that the screen and internal components are waterproof, dust-proof, and corrosion-resistant.

3. Choose a sturdy and durable shell material

The shell of outdoor digital signage needs to be able to withstand the influence of various harsh environments. It is usually made of sturdy metal material and undergoes special outdoor spraying treatment to enhance its weather resistance and corrosion resistance. For example, the shell of the outdoor advertising displays of Simway is treated with outdoor spraying, which can withstand high temperature and cold environment and extend the service life of the device.

 4. Equipped with high-brightness screen

Under direct sunlight, the brightness and contrast of ordinary screens will be seriously affected to recognize. Therefore, a high-brightness screen, usually more than 2000 nits, is important for outdoor digital billboard to ensure the content is still clearly visible under strong light.

 5. Reasonable installation and maintenance strategy

- Installation location selection: Choose a suitable location to avoid installing the device in a place that is easily blocked or has insufficient light. At the same time, consider the audience's viewing angle to ensure that the signage can be clearly seen in different positions.

- Fixed method: Use a reliable fixed method to ensure the installation frame is firm and corrosion-resistant when installed on the wall, and the weight and structural stability need to be considered.

- Daily maintenance: Regularly clean the screen surface, check whether the cooling system is working properly, and clean the dust/ debris inside the device to ensure the long-term stable operation of the device. 

Through the above measures, outdoor digital signage can maintain normal function in extreme weather and ensure the effective transmission and display of information.
