Nowadays, LED display video walls is the dominant field in the field of advertising. Make different trade-offs according to the needs of each project, such as pixel selection, resolution, price, broadcast content, display life and before or after maintenance.
Of course, we must also consider the bearing capacity of the installation site, the brightness around the installation site, the observation interval and angle of the observer, the climate and climatic conditions of the installation site, whether it is rain proof, whether it is ventilated and heat dissipation, and other external conditions. How do you buy LED display?

1. The need to present content. The ratio of length and width is determined according to the actual content. The video screen is generally 4:3 or close to 4:3, and the best ratio is 16:9.
2. Confirm visual distance and visual angle. In order to ensure that in the case of strong light can be seen from a distance, it is necessary to use ultra-high brightness LED.
3. The planning of appearance and shape. Now we can customize the LED display according to the design and shape of the building. For example, the 2008 Olympic Games and the Spring Festival Gala are using the LED display skills to achieve the ultimate perfect visual effect.

4. It is necessary to pay attention to the fire safety of the installation site and the energy saving specification of the project. Of course, the selection of model, brand, LED screen quality, manufacturer qualification, energy conservation and environmental protection, product after-sales service and other aspects are important factors. The display equipment is outdoor, often exposed to sunlight and rain water, and the working environment is bad. If the electronic equipment is affected with damp, it may lead to short circuit or even fire, fault or even fire. Therefore, the structure of the display screen is required to be weatherproof, rainproof and lightning proof.

5. Requirements of installation environment. In order to prevent the display screen from being used normally due to the low temperature in winter, it is necessary to select the industrial integrated circuit chip whose working temperature range is between – 40 ° C and 80 ° C. The ventilation and cooling equipment is installed to make the internal temperature of the screen body between – 10 ℃ and 40 ℃. The axial fan is mounted above the back of the screen to remove heat when the temperature is too high.
6. Cost control. The power consumption of display screen is an important factor to be considered.
