2. Outdoor full-color advertising screen Install lightning protection devices on the display screen and buildings. The main body of the display screen and the casing are well grounded, and the grounding resistance is less than 3 ohms, so that the large current caused by the lightning discharges in time; the display screen may be subject to strong magnetic and magnetic attack caused by lightning.
3. In order to ensure long-distance visibility under strong ambient light conditions, super high-brightness light-emitting diodes must be selected; increase in contrast, wide audience, wide line-of-sight requirements and wide field of vision requirements; large changes in ambient light, especially possible exposure to sunlight Direct.
4. Outdoor full-color advertising screen body and the screen body and the building of the joint must be strictly waterproof and leakproof; screen should have good drainage measures, once the water can be discharged smoothly; pay attention to waterproof, moisture-proof.
5. Install the ventilation equipment to reduce the temperature, so that the internal temperature of the screen is between -10 Â°C ~ 40 Â°C. Axial fans are installed behind the screen body to discharge heat; the display screen itself generates 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, and the display system may not function properly. jobs.
6. Select industrial-grade integrated circuit chips whose operating temperature is between -40Â°C and 80Â°C to prevent the display from failing to start when the temperature in winter is too low.
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 Salt spray test, the test results show that: the products meet the national industrial standards, in line with the salt spray test requirements, even in the marine climate conditions, outdoor full-color advertising screen screen can also be used normally for a long time.
Between the pixels and the module is sealed with an insulating rubber ring to prevent the penetration of moisture; the joint between the decoration and the module is filled with foam rods and filled with high quality weatherproof glue to prevent the water and gas from penetrating into; all the product shell protection grade reaches the pre-discharge IP65 level Above; outdoor full-color advertising screen in vitro decoration is made of high-quality flame retardant aluminum-plastic board with excellent corrosion resistance, and the joints between the plates are closely packed with high-quality weather-resistant glue; three prevention measures: all circuit boards are tested after production The use of special electronic three anti-paint treatment, and apply flame-retardant materials to make it dustproof, moisture-proof, anti-corrosion, flame-retardant properties.
