The production and installation technology of LED display has a great influence on the quality of the display. From the selection of production materials to processing to finished products, every link needs to be strictly checked and refined to every step. In addition, the LED display should be regularly inspected and maintained during the use of the LED display, and remedial measures should be taken in time if quality problems are found.
Nowadays, the application range of LED display screens is constantly expanding, and the number of LED display screen components is also increasing. The quality of LED display screen components has a great impact on the quality of LED display screens. However, the quality of many LED display components varies, which is mainly reflected in the following points: First, the new LED display components are still in the trial stage, and the quality cannot be guaranteed. Second, the professional level and comprehensive quality of the LED display component production personnel are not high. , greater fluidity, and third, the quality of the original LED display components is poor, unable to meet the production and use requirements of LED displays.
Static problem analysis
In the process of LED display production and installation, static electricity has a great impact on the quality of LED display. However, many LED display production and installation companies only know
The importance of static control in the welding of LED display screens, and the lack of understanding of the importance of static control in other links. In the northern region, the climate is cold and dry in winter, and the voltage of static electricity is very high. Static electricity will destroy the LED display circuit, resulting in circuit damage, and 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.
Analysis of Welding Link Control Problems
There will also be many quality problems in the process of LED display welding, which are mainly reflected in the following points: first, the enterprise’s static electricity prevention and control management is not in place, second, the temperature and air humidity of the LED display application are unreasonable, and third, the LED display The welding time of the display components is not well controlled. Fourth, there are quality problems in the welding materials. Fifth, the welding personnel do not have the skills
Professional welding technology, low professional level. Many welding companies do not have professional welding personnel, and the mobility of personnel is relatively large, resulting in a 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 welding personnel did not reasonably control the welding time and temperature, resulting in fog in the LED display, which in turn affects the brightness of the display. Therefore, in order to ensure the quality of Foldable LED Mesh Screen 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 within welding personnel to give certain material rewards or spiritual rewards to employees with outstanding performance, so as to improve the enthusiasm and enthusiasm of welding personnel.
Analysis of LED Display Aging Problems
Under normal circumstances, the LED display should be placed for 72 hours before going out, and this 72 hours is 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 it is impossible to find the quality problems of the LED display and take countermeasures for 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 been aged before they are released. If the LED display is not aged, it will not only affect the quality of the LED display, but also increase the repair and maintenance cost of the LED display, thereby reducing the economic benefits of the application enterprise.
Problem analysis of LED display mask
Usually, indoor LED displays are all LED lights. People will find that many LED displays have better visual effects when viewed from the outside, but the visual effects are not very ideal when viewed from the side, and mosaic phenomena will appear to varying degrees, affecting the LED display. The brightness of the display screen, the cause of this problem is the quality problem of the LED display screen mask. The function of the LED display mask is reflected in the following aspects: one is to protect the LED display, the other is to increase the brightness of the LED display, enhance the color of the background color, and make the LED display and the background color form a sharp contrast. If there is a problem with the quality of the LED display mask or the installation method is incorrect, not only will it not protect the LED display, but it will damage the LED display, affecting the performance and service life of the LED display. The unqualified LED display mask is reflected in the following points: first, the material of the LED display mask is not good; second, there are impurities on the surface of the LED display mask; third, the reflection of the LED display mask is strong; The number of screws is relatively small, and the stability of the LED display mask is poor. Fifth, the LED display mask and the display circuit board cannot be combined. Therefore, in order to ensure the quality of the LED display, it is necessary to ensure the quality of the LED display mask, reasonable material selection, and reasonable installation.
Display module problem analysis
The problems of the LED display module are mainly reflected in the following aspects: one is the quality problem of the module shell, and the other is that the material of the module is not good. In order to ensure the quality of the LED display, it is also necessary to ensure the quality of the LED display module, select high-quality materials, strictly control the amount of module glue used, and prevent the glue from leaking out.
Although the application range of LED display is expanding, there are still many problems in the application process of LED display. Only by solving these problems reasonably can the quality and performance of LED display be guaranteed, the service life of LED display can be extended, and the LED display can be reduced. screen repair costs. LED display quality problems can be reflected in six aspects, any link is very important. Therefore, the staff must formulate a reasonable LED display quality control plan based on the actual situation to ensure the quality of the LED display components and masks, and pay attention to the aging of the LED display when it leaves the factory. In addition, the staff should also do a good job of anti-static on the LED display, otherwise the LED display components will be affected by static electricity, which will eventually lead to damage to the LED display and increase the repair and maintenance costs of the LED display.
