LED display screen is a kind of propaganda medium used in outdoor advertising at present. It has a wide audience and diversified advertising forms, which are favored by advertising companies.So what should we pay attention to when installing outdoor LED displays?Below small make up to introduce a few outdoor LED display installation matters needing attention.
1. The LED display screen and the building shall be installed with lightning arresters: the main body and enclosure of the LED display shall be well grounded, and the grounding resistance shall be less than 3 ohms, so that the large current caused by lightning can be discharged in time.The display screen may be struck by strong electromagnetism caused by lightning.
2. Waterproof measures of LED display panel itself: the screen body and the joint part of the screen body and the building must be strictly waterproof and leakproof;The screen body should have good drainage measures, once water accumulation can be discharged smoothly;Pay attention to waterproof and moisture-proof.The display screen is installed outdoors. It is often exposed to the sun and rain.When electronic equipment gets wet or seriously wet, it will lead to short circuit and even fire.
Three, circuit chip selection: choose working temperature between - 40 ℃ ~ 80 ℃ of industrial-grade integrated circuit chips, prevent winter low temperature which display cannot be started.
Four, install ventilation cooling equipment, makes the screen body internal temperature between - 10 ℃ and 40 ℃ : behind the screen installed above the axial flow fan exhaust heat;The display screen itself needs to generate a certain amount of heat when working. If the ambient temperature is too high and the heat dissipation is not good, the integrated circuit may not work properly or even be burnt, thus making the display system unable to work normally.
5. Ultra-high brightness light-emitting diode must be selected: in order to ensure remote visibility in the case of strong ambient light, ultra-high brightness light-emitting diode must be selected;Increase contrast. Wide receiver area, wide visual range and wide visual field;The ambient light varies greatly, especially from direct sunlight.
6. New wide viewing Angle tube is selected for display medium: wide viewing Angle, pure color, consistent coordination, the external packaging of display medium with service life of more than 100,000 hours is the most popular square barrel with screen edge, silicone sealing and metal-free packaging at present;It is delicate and beautiful in appearance, strong and durable, with the features of direct sunlight, dustproof, waterproof, high temperature proof, circuit short-circuit prevention.
Precautions for the installation of outdoor LED displays are related to the future use and safety of the products, which must be taken seriously and strictly.
