The main problems of the outdoor led display as below:

1)   Outdoor LED Display are installed in outside, they work in severe environments, such as long time sun exposure, torrential rain, fierce gale.

Usually, electronic products will get damage after getting wet or severely damp. even caught fire.

2). The outdoor display may be attacked by strong electricity and magnetism caused by lightning.

3). Ambient temperature changes greatly.

As led display will generate a certain amount of heat when it’s working. If the temperature of the working environment too high and the heat dissipation is not good, the integrated circuit may not work properly or even be burnt, which will cause the display system can’t work well.

4). The view distance needs to be far, wide field of vision.

 

 

In response to the above special requirements, the outdoor display must:

1)   . The led cabinet must be strictly waterproof and leak-proof, also doing good on waterproof and leak-proof about the junction between the display and building.

The led cabinet should have good drainage measures once stagnant water occurs, it can be discharged smoothly.

2). Install lightning protection devices on display screens and buildings. The display body and the case are kept well-grounded, The grounding resistance is less than 3 ohms, so that the large current caused by lightning is discharged in time.

3). Install ventilation equipment to cool down, make the internal temperature of the screen between -10 ℃ ~ 40 , fan installed behind the display to discharge heat for heat removal. 

 

4). Choose industrial-grade integrated circuit chips with operating temperature between -40 ℃ ~ 80 , avoid the led display can’t turn on because the temperature of winter to low.

5). Use high brightness LEDs to ensure visibility under strong light with far-distance.
