Precautions for installing LED display screen

1. Choose an industrial-grade integrated circuit chip with the working temperature of -40℃ to 80℃ to prevent the LED display quad chip from being unable to start due to the low temperature in winter.

2. In order to ensure long-distance visibility under strong ambient light, ultra-high brightness four-way LED must be selected.

3. The display medium is exquisite and beautiful in appearance, durable, and has the characteristics of preventing direct sunlight, dust, water, high temperature and short circuit.

4. The screen body and the joint between the screen body and the building must be strictly waterproof and leakproof; Screen body should have good drainage measures, once there is water, it can be discharged smoothly.

5. Install lightning protection devices on display screens and buildings. The main body and shell of the LED electronic display screen are well grounded, and the grounding resistance is less than 3 ohms, so that the heavy current caused by lightning can be discharged in time.

6. Install ventilation equipment to cool down, so that the temperature inside the screen is between-10℃ and 40℃. An axial fan is installed above the back of the screen body to dissipate heat and prolong the display life of the four-way led.
