The use of outdoor led large screen has relatively high requirements on the use environment. Considering that outdoor led large screen may be affected and destroyed by low temperature, typhoon, rainstorm and lightning weather, the following Suggestions are summarized:

1.High temperature, outdoor led screen is usually a large area, in the application process of large power consumption, the corresponding heat release is also large, plus the external temperature is higher, if you can‘t solve the heat dissipation problem in time, so it is likely to cause circuit board heat short circuit and other problems.In production, ensure the state of the display circuit board is good, as far as possible in the shell design, choose hollow design, conducive to heat dissipation.In the installation, according to the device situation, insist that the display screen is in a good condition of ventilation, and add heat dissipation equipment to the display screen when necessary, such as adding an air conditioner or a fan to help the display screen heat dissipation.

2.Typhoon prevention, outdoor led large screen installation location of many categories, installation methods are also very diverse.Have stick a wall type, Mosaic type, column type, suspension type and so on.So in the typhoon season.In order to make led display equipment do not fall off, there are strict requirements on the display structure of load-bearing steel frame.The engineering unit must design and install in strict accordance with the standard of typhoon resistance level, and at the same time, it must have certain seismic capacity to ensure that the outdoor led screen will not fall off and cause casualties and other hazards.

3.Rain-proof, south of the rainy weather, so the led display itself must have a high level of waterproof protection level to not encounter rain erosion.In the outdoor use environment, the outdoor led large screen should reach the protection level of IP65. The module should be encapsulated with glue, and the waterproof box should be selected. The module and the box should be connected with a waterproof apron.

4.Lightning protection, outdoor led screen lightning protection mainly has four parts

1) direct lightning protection of the outdoor screen. Lightning rods shall be set at or near the top of the steel structure of the screen if the outdoor screen is not within the direct lightning protection scope of nearby tall buildings.

2) outdoor screen inductive lightning protection (large screen power system does 1-2 level power supply lightning protection, signal line with signal lightning protection device.The power system of the machine room shall be protected against lightning at level 3, and the signal out/in machine room shall be equipped with a signal lightning protection device at the equipment end.

3) all led large-screen wiring (power supply and signal) shall be shielded and buried.

4) front end (outdoor screen) and grounding system of machine room shall meet system requirements.
