Today, outdoor LED displays occupy a dominant position in the field of advertising and outdoor events. Depending on the 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 waterproof, whether it is ventilated and dissipated, and other external conditions. So how to purchase outdoor LED display?
1, The need to display the 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. Confirm the viewing 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. The design of the appearance and shape has been able to customize the LED display according to the event design and shape of the building. For example, in the 2008 Olympic Games and the Spring Festival Gala, the LED display technology was applied to the extreme to achieve extreme perfection visual effects.
4. It is necessary to pay attention to the fire safety of the installation site, the energy saving standards of the project, etc. When choosing, the quality of the LED screen, and the after-sales service of the product are all important factors to be considered. The LED display screen is installed outdoors, often exposed to the sun and rain, 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 LED cabinet is to take into account the weather conditions, and be able to protect against wind, rain, and lightning.
5, The installation environment requirements. Select industrial-grade integrated circuit chips with a working temperature between -30°C and 60°C to prevent the display 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 LED screen is between -10 ℃ ~ 40 ℃. An axial flow fan is installed at the back of the screen, which can discharge heat when the temperature is too high.
6. Cost control. The power consumption of the LED display is a factor that must be considered.
