There are only two main use places for LED display screens, one indoor and one outdoor. Whether it is for indoor use or outdoor use, the selection should not be sloppy. Different environments also have certain requirements for selection. YONGS LED display The following specifically discusses the selection of outdoor LED display according to the environment.
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.
3. Design of appearance and shape:
At present, LED displays can be customized according to the design and shape of buildings. For example, in the 2008 Olympic Games and the Spring Festival Gala, LED display technology was applied to the extreme to achieve extremely perfect visual effects.
4. Pay attention to the fire safety and energy saving standards of the installation site:
Of course, when choosing, brand factors, LED screen quality, product after-sales service and other aspects are all important factors to be considered. The display screen is installed outdoors, often exposed to the sun and rain, wind and sun, and the working environment is harsh. Wetting or severe dampness of electronic equipment can cause short circuit or even fire, causing failure or even fire, resulting in loss. 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.
