LED displays, whether in production or use, will appear a variety of failures, Rayling display engineers based on years of experience, summarize the main reasons for these failures. I believe that after reading this article, the reader will have a comprehensive understanding of the causes of LED display failure.
Product quality is the LED display manufacturers need to strengthen and improve the place, should be from the source of control failure, improve the quality of the LED display.
LED display has become a part of people’s lives, street alleys, square stations, all kinds of different sizes and shapes of LED displays can be seen everywhere. It is a system engineering that combines optics, structural mechanics, electronics, and computer science.
According to statistics, more than 80% of LED display failure is caused by the following factors: AC power distribution wire bundles, terminals, connectors, signals and low voltage DC connection wire bundles and connectors, switching power modules, fans, plastic shell components. These interfaces, cables, kragbronne, shells if not selected well, will lead to LED display overall or partial black screen, flower screen, mosaic, no signal, ens. These are also very difficult to maintain problems, so we pay attention to reduce the failure rate in the production process.
80% of the remaining failures are due to the following reasons: welding points, capacitors, terminals, LEDs on the PCBA These reasons will cause the LED display to have blind lights or highlighted, one or more lines are not bright, lack of color, ens., if the control card or software has problems, it will cause the image display is not normal. Outdoor display must be designed strictly according to the detection standards, waterdig, dustproof, wind-resistant, hoë temperatuur, otherwise it is easy to appear a variety of failures, even the entire LED display will be scrapped. Daarbenewens, the display operator should master the relevant basic knowledge, With good use habits, plus professional maintenance personnel, can also reduce the failure rate to a certain extent.
