1、 Wire quality: in most casesLED display screenIn applications, the larger the unit area of the display screen, the greater its power consumption, and the higher the requirements for the stability of wire electrification. Among numerous wire products, the use of wires that meet national standards can ensure their safety and stability. There are three requirements: the wire core is a copper wire conductive carrier, the cross-sectional area tolerance of the wire core is within the standard range, and the insulation and flame retardancy of the rubber wrapping the wire core meet the standards. Compared with general copper-clad aluminum wire cores, wires with smaller cross-sectional areas and insufficient insulation rubber grades, the electrical performance is more stable and less prone to short circuits.


2、 Power Quality: UL certified power products are available for purchaseLED full-color display screenThe best choice for power supply, its effective conversion rate can ensure the safety and stability of power load, and it can also work normally in hot external environments.


IIILED full-color display screenExternal protective structural materials: Most LED display screen products with high fire resistance levels on the market use fire-resistant aluminum-plastic panels, which have excellent fire resistance and strong flame retardancy. The core material has strong oxygen aging performance, with a melting point temperature of 135 ℃ and a decomposition temperature of ≥ 300 ℃. It is environmentally friendly, low smoke and halogen-free, meets SGS flame retardant B-S1, d0, t0, and refers to the use standards UL94 and GB/8624-2006. The aluminum-plastic panel of a typical outdoor LED display screen ages rapidly due to high temperature, rain, and thermal shock, making it easy for rain and dew to seep into the interior of the screen during humid weather seasons, causing electronic components to short circuit and trigger fires.


4、 Plastic kit:LED full-color display screenThe plastic kit is mainly used as the material for the bottom shell of the unit module face mask. The main raw material used is PC fiberglass material with flame retardant function. It not only has flame retardant function, but also does not deform, become brittle or crack under high and low temperatures and long-term use. At the same time, it is used in combination with well sealed glue, which can effectively block rainwater from the external environment from penetrating into the interior and causing short circuits and fires.
