How to choose outdoor LED display according
Today, outdoor LED displays occupy a dominant position in the advertising field. According to the different needs of each project, for example, there will be different trade-offs in the selection of pixels, resolution, price, playback content, display life, and front or rear maintenance. Of course, we must concern 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. Furthermore, we need to consider whether it is rainproof, whether it is a ventilated environment or not, etc. So how to purchase LED displays? Here are some suggestions from CHENKSE.
1. The need to display content
The actual content of the picture determines the ratio of length to width. 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 under strong light conditions, we must use ultra-high brightness LEDs.
3. Appearance and shape of the design
The appearance and shape of the design can now be customized according to the design and shape of the building. For example, in the 2008 Olympic Games and the Spring Festival Gala, the LED display technology is applied to the extreme to achieve perfection. Visual effects.
4. Fire safety and Energy-saving
It is necessary to pay attention to the fire safety of the installation site and the energy-saving standards of the project; of course, brand factors, LED screen quality, product after-sales service and other aspects are important factors. We install the display screens outdoor under in the sun, rain, wind and sun, and the working environment is harsh. If electronic equipment gets wet or severely damp, it can cause short circuit or even fire, cause malfunction or even fire, and cause damage. Therefore, the requirement on the structure is to take into account the weather conditions and be able to protect against wind, rain, and lightning.
5. Requirements of the installation environment
Use industrial-grade integrated circuit chips with a working temperature between -40°C and 80°C to prevent the display from starting up due to low temperatures in winter. Install ventilation equipment to cool down so that the internal temperature of the screen is between -10°C and 40°C. So we can install an axial fan on the top of the back of the screen to dissipate heat when the temperature is too high.
6. Cost control
The power consumption of the display is a factor that we must consider.
