Southbound SA-3.91 Transparent grille LED display

South travel SA-3.91 transparent grid LED display has the characteristics of strip, hollow, transparent, does not affect the ventilation and lighting of the product form. It can be widely used in automobile 4S shops, tourist attractions, hotels, large shopping malls, glass walls and landmark buildings, etc., suitable for the construction of super large atrium display, is the first choice to create a landmark dynamic display landscape.


1. Flat and simple, frame type box splicing, smooth and seamless, efficient and clean,

2. High protection level, strong wind load capacity, hollow grid natural ventilation, screen body wind load capacity is very strong and the need to install cooling equipment, thereby saving costs IP67 protection level above, suitable for outdoor any harsh environment, weather.

3. High permeability 20%-70%, effectively protect the building lighting, farewell to the “screen no light” era.

4. Easy installation, fast maintenance, flame-retardant material and fast self-locking box design, without complex steel structure can be quickly installed by hand, before and after maintenance is simple and fast.

5. Energy saving, environmental protection and low energy consumption, 24 hours a day stable operation 365 days of continuous work, life up to 100,000 hours.

6. All day high and low temperature, all-weather low temperature resistance -40°C up to 60°C, wet and other weather environment.
