Today, outdoor LED displays dominate the advertising field. According to the different needs of each project, such as the choice of pixels, resolution, price, playback content, display life, and front or rear maintenance, there will be different trade-offs.  

Of course, the load-bearing capacity of the installation site, the brightness around the installation site, the viewing distance and viewing angle of the audience, the weather and climatic conditions of the installation site, whether it is rainproof, whether it is ventilated, and other external conditions. So how to purchase LED display? Here are some suggestions from the editor.

1. The need to display content. The aspect ratio of the picture diploma is determined according to the actual content. The video screen is generally 4:3 or the nearest 4:3, and the ideal ratio is 16:9.


2. Confirmation of visual distance and viewing angle. In order to ensure long-distance visibility in the case of strong light, ultra-high-brightness light-emitting diodes must be selected.

Therefore, the requirement on the structural structure is to take into account the weather conditions, and be able to protect against wind, rain, and lightning.


5. Requirements for the installation environment. Select industrial-grade integrated circuit chips whose working temperature is between -40°C and 80°C to prevent the display screen from being unable to start due to the low temperature in winter. Install ventilation equipment to cool down, so that the internal temperature of the screen is between -10 ℃ ~ 40 ℃. An axial flow fan is installed above the back of the screen, which can discharge heat when the temperature is too high.


6. Cost control. The power consumption of the display is a factor that must be considered.
