In addition, no matter what problems occur in the LCD, it is forbidden to assemble the LCD splicing screen by itself (especially for those who are interested in general DIY). Once the LCD splicing screen is not working properly, you can find the manufacturer to help solve it. Since the transformer in the LCD backlight assembly may still have a 1000V high voltage (although it is a micro-current) after a certain period of shutdown, non-professionals may cause new failures of the component if not handled properly.
Moreover, the LCD display screen is very fragile and delicate, and has poor impact resistance. This is because the LCD contains many precision glass components and agile electrical components that can cause damage to the LCD screen and other related components in the event of a strong impact. So be sure to avoid strong shocks. At the same time, it is also important not to put pressure on the surface of the LCD screen, such as pointing a finger to a certain part of the screen, which easily causes the increase of dead pixels.
In addition, if dirt on the surface of the LCD splicing screen is found, the dirt should be removed using an accurate method. The medium to be used is preferably a soft, non-fibrous material such as absorbent cotton, lens paper or soft cloth, and then gently wipe it off with a little glass cleaner. It is forbidden to use a chemical solution such as alcohol or rough. Cloth or paper items, because such materials are prone to scratches. It is important to remind everyone that the cleaning should not be sprayed directly onto the surface of the display screen. It easily flows into the screen and causes short-circuit faults inside the LCD screen, causing unnecessary losses.
LCD splicing screen maintenance coup
[ Huaqiang Security Network News ] Many LCD splicing screens are prone to overheating of certain pixels under long-term work. Once the limit is exceeded, permanent damage will occur, which forms a "bad point". Since the pixel of the liquid crystal splicing screen is composed of a liquid crystal body, when it is continuously operated at full load for more than 96 hours, it will accelerate its aging, and even burn out when it is severe. Therefore, if the user has to work for a long time, it is best to let them rest for a while, or often change the content of the screen at different intervals, because the brightness is reduced while waiting for work, or it is in screen saver mode. Working for a while, this effort can not only delay the aging of the LCD screen, but also avoid hardware damage.
