Nowadays, LED electronic screen has become a part of people’s life. In the streets, squares and stations, there are a variety of LED electronic screens of different sizes and shapes. It is a system engineering integrating optics, structural mechanics, electronics and computer science. According to statistics, 90% of all LED electronic screens in China have large or small defects. Based on years of experience, engineers have summed up the main factors of these defects. With these, we can diagnose the problems from the source and improve the quality of electronic screens.
80% of the defects of LED electronic panel are caused by the following factors: wiring harness, terminal and connector of AC power distribution, signal and low-voltage DC connection harness and connector, switching power supply module, fan, plastic shell components. If these interfaces, cables, power supply and bottom shell are not selected well, all or part of LED electronic screen will be black screen, flower screen, mosaic, no signal, etc. These are also very difficult to protect the question, because we are in the production process is very attention, reduce the fault rate.
Another 80% of the other problems are caused by the following factors: PCBA solder joints, capacitors, terminals, LED lights, lack of protection level of the box, resulting in water leakage and dust accumulation, leakage of screws, hardware and hardware corrosion, control board card. These factors may cause LED electronic screen to have blind light or highlight, one or more lines are not bright, lack of color, etc. if there is any doubt about the control card or software, the picture display will be abnormal. Field LED electronic screen must be strictly in accordance with the inspection specifications to plan, waterproof and dustproof, wind and high temperature resistance, otherwise it is easy to show various problems, and even make all LED electronic screens scrapped. In addition, the operator of electronic screen should grasp the relevant basic knowledge and have good habits of application. In addition, professional protection personnel can also reduce the fault rate to a certain extent.
Shenzhen is a quality-oriented high-tech company f
technology, product quality and business model innovation. Although the profit model is based on accurate promotion of differentiated products, quality is as important as life. From research and development planning to mechanized production, manual assembly, there are strict regulations. Accurate production technology and perfect technical specifications have brought strong quality assurance to the quality, and also brought positive energy to the healthy development of all LED electronic screen industry, and broadened the use space of new LED electronic screen
