Precautions for daily maintenance and cleaning of LCD splicing screen
Precautions for daily maintenance and cleaning of LCD splicing screen
1. It is forbidden to disassemble the splicing screen without the guidance of professionals
LCD splicing screen is famous for its high precision and delicacy. Unlike ordinary CRT LCD splicing screen, components can be replaced at will. In addition, the transformer in the background lighting component of LCD splicing screen may still have 1000V high voltage point after shutdown for a certain time. If non professionals do not handle it well, it may cause new faults of the component, and it may also cause the screen to permanently fail to work, which will not only bring economic losses to the user, but also a lot of trouble. Therefore, no matter what problems occur in the LCD splicing wall, it is forbidden to assemble the LCD splicing screen by yourself. If there is any problem with the screen, the first reaction is to find the splicing screen manufacturer to solve it.
2. The use environment of LCD splicing wall must be continuously dry
This is the primary condition for the normal operation of the LCD splicing large screen, because the interior of the LCD splicing screen is composed of some precision electronic components. If the use environment is too wet, the internal electronic components are prone to oxidation and corrosion, which will affect the circuit. If the time is long, it is prone to short circuit, which will directly affect the use. If you accidentally get water into the body, it's best to place the LCD splicing unit in a more circulating place. If you are not sure that the body is dry, you'd better not power on the splicing screen to avoid permanent damage to the splicing screen.
3. The LCD splicing screen shall avoid displaying the same picture for a long time, and it needs to rest properly during use
Long time overload work can easily cause overheating of some pixels of LCD splicing screen. If it exceeds the limit, it will cause permanent damage. The pixels of the LCD splicing screen are composed of liquid crystal, and the full load service time of the liquid crystal is 96 hours. Therefore, when the full load working time of the LCD splicing screen exceeds 96 hours, aging or even screen burning will occur. Therefore, remind users to pay attention to the use time and avoid working for a long time when using the LCD splicing screen. This can not only prolong the service life of LCD, but also delay the aging process and even avoid hardware damage. In addition, the displayed content is often changed to avoid the internal burn-out and irreparable bad spots (black spots) caused by the overheating of local pixels caused by the long display time of the same picture. If it is necessary to display the same picture for a long time, the best way is to change the picture once or twice in the middle.
4. How can we clean the LCD splicing screen scientifically and reasonably
The LCD splicing wall has been used for a long time, and it is easy to accumulate some dust and dirt on the surface. When the dust reaches a certain thickness, it will affect the display effect of the LCD splicing large screen. At this time, the work of cleaning the LCD splicing screen is inevitable. When cleaning, we have to adopt scientific and reasonable cleaning methods: use soft, non fiber absorbent cotton, lens paper or soft cloth to dip a little glass cleaner to gently wipe off the dust or dirt on the screen. It is forbidden to use organic chemical solvents such as alcohol during cleaning. At the same time, rough cloth or paper objects shall not be used, because these substances are hard and easy to scratch on the screen and affect the display effect. Be careful not to spray the cleaning agent directly on the surface of the display screen to avoid irreparable losses caused by short circuit inside the body.
