2. Outdoor full-color advertising screens are equipped with lightning protection devices on the display screen and buildings. The main body and the outer casing of the display are well grounded, and the grounding resistance is less than 3 ohms, so that the large current caused by lightning is discharged in time; the display may be attacked by strong electric current caused by lightning.
3. In order to ensure long-distance visibility under strong ambient light conditions, ultra-high brightness LEDs must be used; contrast is increased. The audience is wide, the line of sight is far and the field of view is wide; the ambient light varies greatly, especially the sunlight. Direct.
4. The outdoor full-color advertising screen body and the combination of the screen body and the building must be strictly waterproof and leak-proof; the screen body should have good drainage measures, and once the water accumulation can be discharged smoothly; pay attention to waterproof and moisture-proof.
5. Install the ventilation equipment to cool down, so that the internal temperature of the screen is between -10 °C and 40 °C. The axial flow fan is installed on the back of the screen body to discharge heat; when the display screen is working, it must generate a certain amount of heat. If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit may not work properly or even be burned, so that the display system cannot be normal. jobs.
6. Select industrial grade integrated circuit chip with working temperature between -40 °C and 80 °C to prevent the display from starting up due to low temperature in winter.
Outdoor full color advertising display screen body protection products <br> <br> outdoor full color advertising display systems have been involved in anti-acid rain, salt spray, waterproof, moisture-proof, dust-proof, anti-burning, anti-corrosion treatment, by The salt spray test shows that the products meet the national industrial standards and meet the salt spray test requirements. Even in the maritime climate, the outdoor full-color advertising screen can be used normally for a long time.
The pixel and the module are sealed by an insulating rubber ring to prevent moisture from penetrating; the joint between the decoration and the module is filled with foam rods and filled with high-quality weather-resistant glue to prevent moisture from penetrating; the protection level of all products is up to IP65 before discharge. Above; outdoor full-color advertising screen screen exterior decoration is made of high-quality aluminum-plastic composite board with very good corrosion resistance and high-quality aluminum-plastic composite board. The joints between the plates are tightly filled with high-quality weather-resistant glue. Three prevention measures: all circuit boards are in production after testing It is treated with special electronic three-proof paint and coated with flame-retardant materials to make it dust-proof, moisture-proof, anti-corrosive and flame-retardant.
