And the entrance of moisture may cause LED display dead lights, so in the outdoor full color LED display production and construction process, we need to do a good job of waterproof prevention work.
First, the production process of waterproof work
In the production of production LED display, the PCB board to do a good job of anti-corrosion treatment, such as the surface coating three anti-paint, etc., power and power lines to use high-quality accessories. The waterproof box chosen has better sealing performance and the screen body must reach IP65. The welding place is the most likely to be corroded. Pay attention to doing a good job of protective work. The frame that is put forward in particular is that it is easy to rust, and it is good for rust prevention.
Secondly, for different cell board materials, professional waterproof coating is needed. Next, there is no waterproof slot on the cell board set. Finally, attention should be paid to the problem of waterproofing the back panel of the outdoor LED display, because the display screen is used. In addition, the back-panel LED display is not only heat-dissipating, but also has great convenience in handling waterproof performance. When dealing with the back of the waterproof coating, pay more attention to the back of the small strip display aluminum plastic board waterproof performance, use electric drill in the aluminum plate under the design of a row of drain outlet, not only help the display waterproof, but also conducive to display heat dissipation.
Second, on-site installation and construction need to do waterproof work
In the concrete construction site, in the structural design, the combination of prevention and platooning; after the structure is determined, according to the characteristics of the structure, the sealing with the hollow bubble tube structure, the small compression set rate, and the large elongation at break can be considered. The strip material; after selecting the sealing strip material, according to the characteristics of the sealing strip material, a suitable contact surface and contact force are designed so that the sealing strip is extruded into a dense shape. In some installations, waterproof slots and other locations, do a key protection to ensure that there is no water accumulation inside the display.
Third, the daily use of attention
Finally, for outdoor screens, they need to be used frequently, because the working status of the display itself will generate some heat, can evaporate some of the water vapor, greatly reducing the possibility of wet short circuit. The LED display brand manufacturer Lian Chengfa recommends that you use LED display screens in the rainy season at least once a week or more, and turn on the screen at least once a month for more than 2 hours.
Fourth, LED display screen body water correct remedy:
1, with the fastest speed with a fan or other tools, the water LED display screen body completely blow dry.
2. After the panel is fully dried, it is electrified and burned. The specific steps are as follows:
a. The brightness (all white) is adjusted to 10% and the power is aged for 8-12 hours.
b. The brightness (all white) is adjusted to 30% and the electricity is aged for 12 hours.
c. The brightness (all white) is adjusted to 60% and the power is aged for 12-24 hours.
d. The brightness (all white) is adjusted to 80% and the power is aged for 12-24 hours.
e. The brightness (all white) is adjusted to 100% and the power is aged for 8-12 hours.
V. Handling precautions:
1. Do not put the LED screen body that has been in the water into the air box. It is very easy to stuff the LED lights.
2. When the warehouse enters the water, the air box may enter the water, and all the air boxes need to be exposed to sunlight to prevent the water in the box from evaporating into the LED display.
3. Inadequate treatment of the influent LED display screen may affect the stability of the screen body. When the emergency treatment is performed, the phenomenon of continuous dead lights may occur after the screen body is electrified.
4, all water LED display screen body in the air box. For more than 3 days, there is no value for the screen to be repaired. Please handle it carefully.
Rainy season outdoor LED display waterproof moisture and remedy
Wet and rainy weather is a big challenge for LED displays. How to prevent water and moisture in rainy season is the problem that outdoor LED display faces to be solved. Because the outdoor LED display itself is in a more complex environment than indoor ones, it is necessary not only to consider the problem of wetness, but also to perform daily maintenance such as waterproofing. Therefore, a good sealed installation can help reduce the risk of water in the display and periodically clean up the display. The dust attached to the inside and outside of the screen can also help the display to better dissipate heat and reduce the adhesion of water vapor.
