Why does the led screen have field failures

Why does the led screen have field failures? Today, led screens have become a part of people's lives. LED special-shaped screens of various sizes and shapes can be seen everywhere in the streets and square stations. It is a system engineering integrating optics, structural mechanics, electronics and computer science.

According to statistics from United Huiye Technology, 90% of LED displays in China have major or minor faults. Based on years of experience, an electronic engineer summed up the main attribution of these failures. I believe that with these, we can control the failure from the source and improve the quality of the display.

80% of the failures of led screens are caused by AC power distribution harnesses, terminals, connectors, signal and low-voltage DC connection harnesses and connectors, switching power supply modules, fans and plastic housing components. If these interfaces, cables, power supply and bottom case are not properly selected, it will cause a whole or partial black screen, flower screen, mosaic and no signal LED display. These are also difficult to maintain issues.

United Huiye engineers emphasized that we only pay attention to them during the production process to reduce the failure rate. The other 80% of the failures are caused by the following reasons: PCBA solder joints, capacitors, terminals, LED lamps, insufficient protection level of the box, resulting in water leakage and dust accumulation, water leakage screw hardware corrosion, and control boards. These reasons will cause the LED screen to be blind or bright, one or more lines are not bright, lack of color, etc.

If there is a problem with the control card or software, the image display will be abnormal. Outdoor LED displays need to be designed in strict accordance with testing standards, waterproof, dustproof, wind-resistant, and high-temperature resistant, otherwise various failures are prone to occur, and even the entire LED display will be scrapped. The engineers of United Huiye Technology suggested that, in addition, the operators of the display screen should master the relevant basic knowledge and have good usage habits.

Also, professional maintenance can reduce speed. .
