The production and installation technology of LED display screen has a great influence on the quality of display. From the choice of production materials to processing to finished products, each link needs to be strictly checked and detailed to every step. In addition, in the process of using LED display, LED display should also be regularly checked and maintained. If the quality problems are found, remedial measures should be taken in time.
Today, the scope of LED display applications continue to expand, and the number of LED display components is also increasing, and the quality of LED display components has a great impact on the quality of LED display. However, many of the LED display element is mainly embodied in quality uneven in quality, the following points: one is the new LED display element is still in the trial stage, the quality can not be guaranteed, two is the professional level and comprehensive quality of the LED display element of production personnel is not high, greater mobility, the three is the LED display elements of poor quality of the original, not the LED display the production and use of demand.
1. electrostatic problems analysis
In the process of production and installation of LED display, static electricity has a great influence on the quality of LED display. However, many LED display production and installation enterprises only know
To the importance of electrostatic control in the welding process of LED display screen, there is insufficient understanding of the importance of electrostatic control in other links. In the north, winter cold and dry climate, the electrostatic voltage is very high, will destroy the static LED display circuit, the circuit is damaged, the performance and service life of LED display will be affected in different degrees. Therefore, in the LED display production and installation process, we must pay attention to anti-static control, to avoid damage to the LED display.
2. welding link control problem analysis
There are many quality problems in welding process will LED display, mainly reflected in the following points: one is the electrostatic prevention and control of enterprise management is not in place, the two is the LED display application temperature and air humidity control is not reasonable, the three is the LED display element welding time control is not good, the four is the quality problems of welding materials, five is the welding personnel do not have
Professional welding technology, professional level is low. Many welding enterprises do not have professional welding personnel, the mobility of personnel is relatively large, leading to lack of technical guarantee for welding of LED display screen. LED display in use after a period of time, the brightness of the screen becomes low, the reason for this phenomenon is not reasonable to control the welding welding personnel time and temperature, resulting in LED display memory in fog, thereby affecting the brightness of the screen. Therefore, in order to ensure the quality of LED display and control welding problems properly, welding enterprises must strengthen personnel training, and continuously improve the professional level and overall quality of welding personnel. In addition, welding enterprises can set up rewards mechanism in the welding personnel, and give some material rewards or spiritual rewards to the excellent employees, so as to improve the enthusiasm and enthusiasm of the welding staff.
Aging analysis of LED display screen
Normally, the LED screen should be placed 72 hours before the show, and the 72 hours are LED screen aging time. However, from the actual situation, many LED display manufacturers do not display the aging process, so that we can not find the quality problems of the LED display, nor can we take measures to solve the quality problems. In fact, many quality problems found in the process of the LED display to the LED display, LED display a lot of much maintenance, the main reason is that the LED display no aging treatment on stage before. If we do not deal with the aging of the LED screen, 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.
4. LED screen mask problem analysis
Typically, LED display rooms are LED lights, people will find better visual effect from the appearance of many LED display, but from the side the visual effect is not very ideal, have varying degrees of mosaic phenomenon, affecting the brightness of the LED display panel, the cause of the problem is the existence of LED display screen mask quality problems. LED display mask role in the following aspects: first, to protect the LED display, two is to enhance the brightness of the LED display, enhance the color of the background, so that LED screen and background contrast. If the LED display mask quality problems or the installation method is not correct, not only to protect the LED display, it will destroy the LED display, affects the performance and service life of LED display screen. LED display screen mask unqualified reflected in the following points: one is the LED display mask material is not good, there are two impurity LED display mask surface, three is the LED display strong reflective mask, four is the LED display mask fixing screw number is relatively small, LED display mask less stable, five is the LED display screen mask and display circuit board cannot combine. Therefore, in order to ensure the quality of LED display, it is necessary to ensure the quality of LED screen mask, reasonable selection, reasonable installation.
5. display module problem analysis
LED display module problems are mainly reflected in the following aspects: first, the module shell quality problems; two, the module material is not good. To ensure the quality of LED display, we also need to ensure the quality of LED display module, select high quality materials, strictly control the use of module glue, to prevent leakage of glue.
Although the scope of application of the LED display screen is constantly expanding, but LED still exist many problems in the application process, the only reasonable solution to these problems, in order to ensure the quality and performance of the LED display, LED display prolong service life, reduce the maintenance cost of LED display. LED display quality problems can be reflected in six aspects, any link is crucial. Therefore, the staff must combine the actual situation, reasonable formulation of LED display quality control program, to ensure the quality of LED display components and masks, pay attention to the LED display factory aging problem. In addition, the staff should also do the anti-static LED display, LED display components will be affected or static, resulting in LED display damage, increase the maintenance and maintenance cost LED display.
