(1) The display screen is installed outdoor led panels, 日光や雨にさらされることが多い, and the dust cover is blown by wind, resulting in a harsh working environment. Electronic devices that are wet or severely damp can cause short circuits or even fires, leading to malfunctions or even fires, 損失の原因となります. The screen and the junction between the screen and the building must be strictly waterproof and leak proof; The screen should have good drainage measures to ensure smooth drainage in case of accumulated water.
(2) LED screens may be subjected to strong electrical and magnetic attacks caused by lightning. Install lightning protection devices on LED display screens and buildings. The main body and shell of the LED display screen should be well grounded, with a grounding resistance of less than 3 オーム, to timely discharge large currents caused by lightning.
(3) The ambient temperature varies greatly. The LED display screen itself needs to generate a certain amount of heat during operation. 周囲温度が高すぎて放熱が悪い場合, the integrated circuit may not work properly, and even be burned out, causing the display system to malfunction. Install ventilation equipment to cool down and keep the internal temperature of the screen between -10 ℃ and 40 ℃. Install an axial fan above the back of the screen to dissipate heat. Select industrial grade integrated circuit chips with a working temperature between -40 ℃ and 80 ℃ to prevent the display screen from being unable to start due to low temperatures in winter.
(4) Wide audience, long visual range and broad field of vision required; The ambient light varies greatly, especially when exposed to direct sunlight. It has the characteristics of preventing direct sunlight, ほこり, 水, 高温, and short circuit in circuits
