Inspection and maintenance quality problems of LED display components are divided into 4. Whether the stretching speed of the electronic universal testing machine meets the standard analysis

. In addition, the LED display shall be regularly inspected and maintained during the use of the LED display, and remedial measures shall be taken in time if quality problems are found

nowadays, the application scope of LED display screen is 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 screen. However, the quality of many LED display components varies from good to bad, 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 production personnel of LED display components are not high, and the fluidity is large; third, the quality of the original LED display components is poor, which can not meet the production and use needs of LED display

1, 1 Analysis of electrostatic problems

in the process of production and installation of LED display screen, static electricity has a great impact on the quality of LED display screen. However, many LED display production and installation enterprises only recognize the importance of static electricity control in the welding link of LED display, and they do not have enough understanding of the importance of static electricity control in other links. In northern China, the weather is cold and dry in winter, and the static voltage is very high. Static electricity will damage the circuit of LED display screen, resulting in circuit damage. The performance and service life of LED display screen 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 damaging the LED display

1, 2 Analysis of welding control problems

there are also many quality problems in the welding process of LED display screen, which are mainly reflected in the following points: first, the enterprise's electrostatic prevention and control management is not in place; second, the application temperature and air humidity of LED display screen are not reasonably controlled; third, the alignment of the sample in the LED display fixture is quite important; the welding time of the screen element is not well controlled; fourth, there are quality problems in the welding materials, Fifth, the welding personnel do not have

professional welding technology, and their professional level is low. Many welding enterprises do not have professional welding personnel, and the personnel mobility is relatively large, resulting in the lack of technical support for LED display welding. After the LED display screen is used for a period of time, the brightness of the display screen will become low. The reason for this phenomenon is that the welding personnel do not reasonably control the welding time and temperature, resulting in fog in the LED display screen, which affects the brightness of the display screen. Therefore, in order to ensure the quality of LED display screen and reasonably control welding problems, welding enterprises must strengthen personnel training and continuously improve the professional level and comprehensive quality of welding personnel. In addition, the welding enterprise can set up a reward mechanism within the welding personnel to give certain material or spiritual rewards to the employees with excellent performance, so as to improve the work enthusiasm and enthusiasm of the welding personnel

1, 3 Analysis of aging problems of LED display screen

generally, the LED display screen should be placed for 72 hours before leaving the site, which belongs to the aging time of LED display screen. However, judging from the actual situation, many LED display screens Jinan new era assaying Instrument Co., Ltd. have been producing experimental machines for customers in good faith for many years, following the principle of big manufacturers. We can rest assured that our product manufacturers do not aging the display screens, so we can not find the quality problems of LED display screens and take countermeasures against the quality problems. In fact, many quality problems of LED displays need to be found during the use of LED displays. Many LED displays need to be repaired many times. The main reason is that the LED displays are not aged before leaving the site. If the LED display screen is not aged, it will not only affect the quality of the LED display screen, but also increase the maintenance and maintenance costs of the LED display screen, thus reducing the economic benefits of the application enterprises

1, 4 Analysis of LED display screen mask problems

generally, indoor LED display screens are led lights. People will find that many LED display screens have good visual effect from the appearance, but the visual effect is not very ideal from the side. Mosaic phenomenon will appear in varying degrees, affecting the brightness of LED display screen. The reason for this problem is the quality problem of LED display screen mask. The function of LED display screen mask is reflected in the following aspects: first, protect the LED display screen; second, improve the brightness of the LED display screen and enhance the color of the background color, so that the LED display screen 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, it will not protect the LED display, but will damage the LED display and affect 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 poor; second, there are impurities on the surface of the LED display mask; third, the LED display mask has strong reflectivity; fourth, the number of fixing screws of the LED display mask 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 LED display screen, we must ensure the quality of LED display screen mask, reasonable material selection and reasonable installation

1, 5 display module problem analysis

led display module problems are mainly reflected in the following aspects: first, the module shell has quality problems, and second, the module material is not good. In order to ensure the quality of LED display screen, it is also necessary to ensure the quality of LED display screen module, select high-quality materials, and strictly control the usage of module glue to prevent glue leakage

although the application scope of LED display screen continues to expand, there are still many problems in the application process of LED display screen. Only by reasonably solving these problems can we ensure the quality and performance of LED display screen, prolong the service life of LED display screen and reduce the maintenance cost of LED display screen. The quality problem of LED display screen can be reflected in six aspects, and any link is crucial. Therefore, the staff must reasonably formulate the quality control scheme of LED display screen in combination with the actual situation, ensure the quality of LED display screen components and masks, and pay attention to the factory aging of LED display screen. In addition, the staff should also do a good job in the anti-static of the LED display screen, otherwise the LED display components will be affected by static electricity, which will eventually lead to the damage of the LED display screen in strict compliance with the building energy conservation forced standard, increasing the maintenance and maintenance costs of the LED display screen
