With the continuous development of LED display technology, the variety of LED display screen products is more and more rich, and its application scenarios are more and more extensive. Due to the difference of indoor and outdoor temperature, the maintenance and protection work is also different. Outdoor LED display screen installation should be well protected and maintained to prevent the influence of outdoor environment on the normal use of LED display screen.

How to heat and rain proof outdoor LED display? Outdoor LED display screen protection measures:

1. For the lightning protection measures of the installation building and screen body, in order to prevent the LED display screen from strong electromagnetic attack caused by lightning, the screen body and outer packaging protection layer of LED display screen must be grounded, and the resistance of grounding line should be less than 3 Ω, so that the current caused by lightning can be discharged from the ground wire in time.

2. The waterproof, dust-proof and moisture-proof measures of the whole screen body shall be seamless at the junction of the box and the box, and the joint of the screen body and the stressed installation object, so as to avoid water leakage and damp. There should be good drainage and ventilation measures in the interior of the screen. If there is water accumulation inside, it can be treated in time.

3. As for the selection of circuit chips, in the northeast of China, the temperature in winter can reach 10 degrees below zero. When selecting circuit chips, it is necessary to select industrial chips with working temperature of minus 40 degrees centigrade, which means 80 degrees centigrade, so as to avoid the situation that the display screen can not start due to too low temperature.

4. Thermal maintenance for outdoor LED display screen users, we must pay attention to the temperature change of LED display screen, as high temperature will lead to the complete destruction of LED display screen. It is recommended that the LED display screen within 20 square meters should not use air conditioning, and two small fans should be used.

5. Ventilation measures should be taken inside the screen. When the screen is powered on, certain heat will be generated. If the heat can not be discharged and accumulated to a certain extent, the internal environment temperature will be too high, which will affect the work of the integrated circuit, and in serious cases, it can lead to burnout. So far, the MIP brilliant display screen can not work. Therefore, it is necessary to do a good job of ventilation and heat dissipation measures inside the screen body, and the temperature of the internal environment should be kept between minus 10 ℃ and 40 ℃.
