Looking for led screen suppliers usa
? What need to pay attention to the purchase of high-quality outdoor led screen, outdoor led screen usa suppliers to share the following knowledge, first,look at the screen size problem!
The size of the screen is determined based on the displayed content; the size of the video screen is generally 4:3 or close to 4:3; the ideal ratio is 16:9.Even if the resolution is low, try to choose a large area.
Factors to Consider in the Dimensional Design of Outdoor LED screen:
1, site space conditions;
2. The need to display content;
3, display unit template size (indoor screen) or pixel size (outdoor screen).
Outdoor led screen design and installation should consider factors:
1. The display screen is installed outdoors, often exposed to the sun, rain, dust, and the working environment is harsh. If the electronic device is wetted or severely dampened, it will cause a short circuit or even a fire, causing a malfunction or even a fire, resulting in loss;
2. The temperature of the environment changes greatly. When the display screen works, it must generate a certain amount of heat. If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit may not work properly, or even be burned, and the display system may not work properly.
3, the display may be subject to lightning-induced strong electric magnetic attack;
4. The audience is wide, the line-of-sight distance is long, and the field of vision is wide; the ambient light changes greatly, and in particular it may be exposed to direct sunlight.
For the above special requirements, outdoor LED display must do:
1. In order to ensure long-distance visibility under strong ambient light conditions, ultra-high brightness light-emitting diodes must be used;
2. The screen body and the joint between the screen body and the building must be strictly waterproof and leakproof; the screen body must have good drainage measures and can be discharged smoothly in the event of water accumulation;
3, install ventilation equipment cooling, so that the internal temperature of the screen between -10 °C ~ 40 °C. Axial fan is installed above the screen body to discharge heat;
4. Install lightning protection devices on display screens and buildings. The main body of the display screen and the casing are well grounded, and the grounding resistance is less than 3 ohms, so that the large current caused by the lightning discharges in time;
5. Select industrial-grade integrated circuit chips whose operating temperature is between -40°C and 80°C to prevent the display from starting when the temperature is too low in winter.
6. The display medium adopts a new wide viewing angle tube, wide viewing angle, pure color, consistent coordination, and a lifespan of more than 100,000 hours.
