With the popularization and application of LED displays, the diversified development of display products such as full-color LED displays and outdoor LED advertising screens has greatly increased the colorful world of people. All industries, whether campus, station or plaza, LED display can bring visual effects to people, adding vitality, especially outdoor LED advertising screen. However, in practical applications, the installation of outdoor LED advertising screens has become the focus of attention, so what is the key point of installing outdoor full-color LED advertising screens?
- Waterproof, dustproof and moisture proof of the whole screen: the connection between the box and the box, the combination of the LED display body and the mounted object should be seamlessly connected to avoid water leakage and moisture. Inside the screen, there must be good drainage and ventilation measures. If there is water in the screen, it can be disposed of in time.
- The inside of the LED display body should be well ventilated: when the screen is powered and running, it will generate a certain amount of heat. If the heat is not discharged and accumulates to a certain extent, the internal ambient temperature will be too high. Therefore, ventilation and heat dissipation measures are required inside the screen body, and the temperature of the internal environment is maintained between minus 10 degrees and 40 degrees.
3, the choice of circuit chip: In the northeast of China, the temperature in winter can generally reach minus ten degrees, so when choosing a circuit chip, you must choose a working temperature of minus 40 degrees Celsius and 80 degrees Celsius.
- Pay attention to lightning protection of buildings and screens: In order to avoid strong electromagnetic waves caused by lightning strikes, the screen display of the LED display and the protective layer of the outer packaging must be grounded. The resistance of the grounding wire should be less than 3 ohms. This allows the current caused by lightning to be discharged from the ground in time.
