LED outdoor screen installation requirements In order to make the outdoor led display in a long-term normal operating state, the engineers will test many possible problems when designing and installing, such as the following: First, the brightness of the indoor screen should be different It is several times to several dozen times lower than the outdoor screen; putting the indoor screen outdoors is as if the television is not outdoors. Therefore, outdoor screens must use ultra-high-brightness LEDs, and in order to further increase the brightness and increase the viewing distance, a plurality of ultra-brightness LEDs are often packaged in one pixel. Secondly, outdoor screens must be protected from (rain) water, direct sunlight, dust, heat, wind, and lightning, while indoor screens need not consider these issues.
At present, the main problems of outdoor screens are as follows:
1. The screen is installed outdoors, often in the sun, rain and wind. Cover, bad working conditions. If the electronic device is wetted or severely dampened, it may cause a short circuit or even a fire, causing a malfunction or even a fire, resulting in damage.
2. The screen may be subject to strong electric and magnetic shocks caused by lightning.
3. The temperature of the environment changes greatly. When the screen is working, it will 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, so that the display system cannot work normally.
4. Audience breadth, line-of-sight requirements, and vision requirements. Ambient light changes greatly, in particular, it may be exposed to direct sunlight.
Solution and application requirements:
1. The screen and the joint between the screen and the building must be strictly waterproof and leakproof. The screen body should have good drainage measures, and once discharged, the water can be discharged smoothly.
2. Install lightning protection devices on screens and buildings. The main body of the 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.
3. Install the ventilation equipment to reduce the temperature, so that the internal temperature of the screen is between -10 °C ~ 40 °C. An axial fan is installed behind the screen body to discharge heat.
4. Select an industrial integrated circuit chip with an operating temperature between -40°C and 80°C to prevent the screen from starting when the winter temperature is too low.
5. In order to ensure long-distance visibility under strong ambient light conditions, ultra-high brightness LEDs must be used.
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. The outer package of the display media is currently the most popular covered square tube, sealed with silicone, and non-metallic assembly. Its exquisite appearance, sturdiness and durability, with direct sunlight, dust, waterproof, anti-high temperature, anti-circuit short circuit characteristics, the industry is known as the five defenses.
LED display viewing distance is calculated <br> <br> viewing distance by calculating the LED display, you can help us identify the most appropriate distance from the viewer, and. From the perspective of LED display, it can play its unique display effect.
The color mixing distance RGB three-color mixing to a single color distance:
Pixel pitch (mm) × 500/1000
The smallest viewing distance can show the distance of the smooth image:
Pixel pitch (mm) × 1000/1000
The most suitable viewing distance can be seen by the viewer:
Pixel pitch (mm) × 3000/1000
Farthest viewing distance: screen height (m) × 30
