Six suggestions for choosing outdoor LED display screens
Nowadays, outdoor LED displays dominate the advertising industry. According to the different requirements of each project, such as the choice of pixels, resolution, price, playback content, display screen lifespan, and front or rear maintenance, there will be different trade-offs.
Of course, it is also necessary to consider the load-bearing capacity of the installation site, the brightness around the installation site, the viewing distance and angle of the audience, the weather and climate conditions of the installation site, whether it is rainproof, whether it is ventilated and cooled, and other external conditions. So how to purchase LED display screens? Here are some suggestions from the editor.
1. The need to display content. The aspect ratio, graphics and text are determined based on the actual content. For video screens, it is generally 4:3 or close to 4:3, with an ideal aspect ratio of 16:9.
2. Confirmation of visual distance and perspective. In order to ensure long-distance visibility in strong light conditions, ultra-high brightness light-emitting diodes must be selected.
3. The design of the appearance shape can now be customized according to the design and shape of the building, such as the 2008 Olympic Games and Spring Festival Gala, which applied LED display technology to the extreme to achieve extremely perfect visual effects.
4. Attention should be paid 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 that need to be considered. The display screen is installed outdoors, often exposed to sunlight, rain, wind, and sun, and the working environment is harsh. Electronic devices that are exposed to moisture or severe dampness can cause short circuits or even fires, leading to malfunctions or even fires, resulting in losses. So the requirement in terms of structural design is to consider weather conditions and be able to prevent wind, rain, and lightning.
5. Requirements for installation environment. Select industrial grade integrated circuit chips with a working temperature between -40 ℃ and 80 ℃ to prevent the display screen from failing to start due to low winter temperatures. Install ventilation equipment to cool down and keep the internal temperature of the screen between -10 ℃ and 40 ℃. Install an axial flow fan above the back of the screen to dissipate heat when the temperature is too high.
6. Cost control. The power consumption of the display screen is a necessary factor to consider.
