Today, outdoor full-color LED displays occupy a dominant position in the advertising field. According to the different requirements of each project, such as the choice of pixel, resolution, price, playback content, LED 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 climate conditions of the installation site, whether it is rain-proof, whether it is ventilated and heat-dissipating, and other external conditions should also be considered. So how to purchase LED display? Next, LCF sent the editor to share a few suggestions with you.

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

2. Confirmation of viewing distance and viewing angle. In order to ensure long-distance visibility under strong light conditions, ultra-high brightness light-emitting diodes must be selected. We all know that P represents the pixel pitch, and the value behind P mainly refers to the distance between the pixels of the display module, which is usually called the pixel pitch in the LED display industry. And the smaller the value of this dot pitch, the higher the unit pixel, the clearer the display screen will be, and the more suitable for close viewing. Therefore, for outdoor LED displays, if the distance is relatively close, it is recommended to use a display between P2.

If the area is ≥100 square meters and the viewing distance is beyond 30M, it is recommended to use a display screen above P16. Because the display screens above P16 are suitable for customers who do not require high definition and display area is relatively large, and can display simple images and video images in the distance. The farther the viewing distance is, the larger the area of the screen will be. If the requirements for the clarity of the display screen are relatively low, you can choose a display screen with a large dot pitch.

3. The design of the appearance and shape. At present, it is possible to customize the LED display screen according to the design and shape of the building. For example, classic projects such as the 2008 Olympic Games, the Spring Festival Gala, and the 2021 Winter Olympics have applied LED display technology to the extreme to achieve extremely perfect visual effects.

4. It is necessary to pay attention to the fire safety of the installation site and the energy saving standards of the project. Of course, when choosing, brand factors, LED screen quality, product after-sales service and other aspects are all important factors to consider. The LED display is installed outdoors, often exposed to the sun, rain, wind and sun, and the working environment is harsh. Wet or severely damp electronic equipment may cause a short circuit or even a fire, resulting in failure or even a fire, resulting in losses. Therefore, the requirement on the structure is that it needs to take into account the weather conditions and be able to prevent wind, rain, and lightning.

5. Requirements for the installation environment. Select an industrial-grade integrated circuit chip with a working temperature between -40°C and 80°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 screen is between -10°C and 40°C. An axial flow fan is installed above the back of the screen to discharge heat when the temperature is too high.

6. Cost control. The power consumption of the LED display is an element that must be considered.

7. According to the area. If the playback area is less than 20 square meters, it is recommended to use a high-definition refresh outdoor screen between P2.5-P5. For an area between 20 and 30 square meters, it is recommended to use a full-color LED display between P5-P10. For an area between 30-100 square meters, it is recommended to use a large LED screen between P10-P16 for a viewing distance of 10 meters. .

In addition to the above, everyone should also pay attention to the fire safety of the site and the after-sales service of the screen. For example, if the equipment is installed outdoors, it must be considered whether it will cause a short circuit or fire, resulting in losses.

The above are the seven suggestions for the purchase of outdoor full-color LED displays compiled by LCF Xiaobian.
