First, the led screen and the screen body and the combination of the screen with the building must be strictly waterproof and leakproof; screen to have good drainage measures, in the event of stagnant water can be discharged smoothly.
Second, in the led display and lightning protection devices installed on the building. Main body and shell of the display are well grounded. The grounding resistance is less than 3 ohms, so that the large current caused by lightning can be discharged in time.
Third, the installation of cooling ventilation equipment, outdoor led display internal temperature between -10 ℃ ~ 40 ℃. Behind the screen body installed axial fan, discharge heat.
Fourth, the selection of the operating temperature -40 ℃ ~ 80 ℃ between industrial grade integrated circuit chips, to prevent the winter temperature is too low to make the led display can not be started.
Fifth, in order to ensure long-distance visual environment under intense light, outdoor led display must use ultra-high brightness light-emitting diodes.
Sixth, led display media selection of new wide viewing angle tube, wide angle, pure color, consistent coordination, life expectancy more than 100,000 hours. Outer packing of the display media is the most popular square cylinder with covered edge, sealed with silicone and nonmetallic assembly. Its appearance is exquisite, beautiful and durable, with direct sunlight, dustproof, waterproof, anti-heat and short circuit prevention "Five defenses" features.
