Analysis of the quality problems of the 'three' LED display components

2021-07-12
What are the quality problems of LED display components? LED display manufacturers have summarized the following three quality issues for analysis:
1. Analysis of static electricity problems
In the process of LED display production and installation, static electricity has a great influence on the quality of LED display. However, many LED display production and installation companies only know
To the importance of static control in the LED display welding link, there is insufficient understanding of the importance of static control in other links. In the north, the climate is cold and dry in winter, and the voltage of static electricity is very high. Static electricity will damage the LED display circuit and cause circuit damage. The performance and service life of the LED display will be affected to varying degrees. Therefore, in the process of LED display production and installation, we must pay attention to anti-static control to avoid damage to the LED display.
2. Analysis of welding link control problems
There are many quality problems in the LED display welding process, which are mainly reflected in the following points: First, the enterprise's static prevention and control management is not in place, and the second is the unreasonable control of the temperature and air humidity of the LED display. The third is that the welding time of LED display components is not well controlled, the fourth is that there are quality problems in the welding materials, and the fifth is that the welding personnel do not have it.
Professional welding technology, the level of professionalism is low. Many welding companies do not have professional welding personnel, and the mobility of the personnel is relatively large, resulting in the lack of technical support for LED display welding. After the LED display is used for a period of time, the brightness of the display will become lower. The reason for this phenomenon is that the welder does not reasonably control the welding time and temperature, resulting in fog in the LED display, which affects the brightness of the display. Therefore, in order to ensure the quality of LED display screens and reasonably control welding problems, welding companies must strengthen personnel training and continuously improve the professional level and comprehensive quality of welding personnel. In addition, welding companies can set up a reward mechanism for welding personnel, and give certain material or spiritual rewards to outstanding employees, so as to improve the enthusiasm and enthusiasm of welding personnel.
3. Analysis of the aging problem of LED display
Under normal circumstances, the LED display should be placed for 72 hours before going out of the field. This 72 hours belongs to the aging time of the LED display. However, from the actual situation, many LED display manufacturers do not perform aging treatment on the display, so that the quality problems of the LED display cannot be found, and they cannot take countermeasures to the quality problems. In fact, many quality problems of LED display screens need to be discovered during the use of LED display screens. Many LED display screens need to be repaired many times. The main reason is that the LED display screens have not undergone aging treatment before they are released. If the aging treatment of the LED display is not carried out, it will not only affect the quality of the LED display, but also increase the maintenance and maintenance costs of the LED display, thereby reducing the economic benefits of the application enterprise.
