First: pay attention to the use time to prevent long-term work
Long-term overload work is very simple to cause some pixels of the LCD splicing screen to overheat, if the limit is exceeded, it will cause permanent damage. The pixels of the LCD splicing screen are composed of liquid crystals. When the continuous full-load operation is more than 95 hours, it will accelerate the aging process of the LCD splicing screen, and even more severely, it will burn out. Therefore, users should pay attention to the time of use when using the LCD splicing screen to prevent long-term work. This can not only extend the service life of the LCD screen, delay the aging process, and prevent hardware damage.
Second: Maintain a dry environment
This is an important condition for the normal operation of the LCD splicing screen. The internal planning of the LCD splicing screen is very delicate. If the operating environment is humid, it will simply oxidize and corrode to form short-circuit and other appearances, which will bring endless economic losses to the user. Therefore, try to stick to the boring application environment of LCD splicing screens. If you find that there is moisture on the outside of the screen, wipe it off with a soft cloth gently, and then turn on the power. If moisture has entered the LCD splicing screen, the LCD splicing screen must be placed in a well-ventilated or warm place to allow the moisture to evaporate. If the situation is more severe, usually users can ask professionals to assist in handling. Do not allow the LCD splicing screen to be powered on when the moisture is not removed, otherwise it will cause the liquid crystal electrode to be corroded and cause permanent damage to the LCD splicing screen.

Third: Do not disassemble the LCD splicing screen without authorization
Because the LCD splicing screen is very fine, unlike the usual CRT LCD splicing screen, the parts can be replaced at will. In addition, the transformer in the background lighting assembly of the LCD splicing screen may still have a high voltage of 1000V after a certain time of shutdown. If the non-professionals do not handle it well, it may cause new problems in the assembly, and may cause the screen to permanently fail to operate in severe cases. Create unnecessary troubles for users. Therefore, no matter what questions the LCD splicing screen presents, it is forbidden to install the LCD splicing screen by yourself. If the LCD splicing screen is not working properly, you can find the manufacturer to help you deal with it.
Fourth: Set the best resolution
If there is a DVI port on the graphics card directly output to the digital port of the LCD, there will be no pixel loss in this brand new flashing method.
When flashing images with a resolution smaller than the best resolution, LCD flashing uses two methods to flash: one is centered flashing, and the other is extended flashing. What is centered flash? For example, when the LCD splicing screen with the best resolution of 1024768 flashes at 800600 resolution, only the 800600 image in the center flashes the picture, and the surrounding is dark shadows. This method is because of the signal resolution. There is also a one-to-one correspondence, so the picture is clear, and it is a pity that the picture is too small. The expansion method is to expand the 800600 screen to a 1024768 resolution through the calculation method to flash, because the signal processed by this method does not correspond to the pixel one-to-one, although the screen is large, it is relatively vague. No matter which kind of flashing method is not ambition, so it is recommended to choose the best resolution recommended!
Fifth: Prevent fierce collision
Because the LCD splicing screen contains many fine glass elements and electrical components, the screen of the LCD splicing screen is very delicate, and the ability to resist impact is relatively poor. Once it is hit hard, it will cause damage to the LCD splicing screen and other related parts. In addition, do not put pressure on the surface of the LCD splicing screen, such as tapping a certain part of the screen with your finger.
Sixth: Update the screen display to prevent the same screen from being displayed for a long time
If the LCD splicing screen flashes the same picture for a long time, it is very simple to cause some pixels to overheat, which will cause internal burnout and cause dead pixels. This damage is irreversible and cannot be corrected. If you don't use it for a long time, close the LCD splicing screen; if you don't need it for a while, choose the screen maintenance program. Maybe you can lower the brightness of the splash screen, or make the screen all white, but this approach only maintains the LCD. The light pipe at the back is still working, and the best way is to directly close the LCD splicing screen.
Seventh: Accurately distinguish the splash screen appearance of the LCD splicing screen
The occasional splash screen is an unavoidable situation during the imitation/digital conversion process. It is mainly due to the influence of the imitation signal output interface. For example, the clock and phase of the pixel are not synchronized with the imitation signal output, which will also cause the appearance of the flash screen. This appearance is usually It is called "Pixel Jitter". In order to deal with such questions, there is usually an "active setting" function on the LCD splicing screen. Its function is to analyze the input signal and adjust the LCD splicing screen to the best condition. It can also be adjusted by itself through the two functions of phase and clock. However, if it is a regular splash screen or a splash screen that is often unknown, then it needs to be checked. If the problem of poor cross-sectional contact is ruled out, it is liquid crystal The splicing screen itself is faulty.
Eighth: Accurately organize the LCD splicing screen
The LCD splicing screen has been used for a long time, and there is simply some dust and grime. It is inevitable to organize the LCD splicing screen. When finishing, we must choose an accurate finishing method: use soft, non-fiber absorbent cotton, lens tissue or soft cloth to moisten a small amount of glass cleaner, and gently wipe off the dust or grime on the screen.
Do not use organic chemical solvents such as alcohol, or rough cloth or paper when finishing, because these substances are prone to scratches and affect the flashing effect. Also be careful not to spray the cleaning agent directly on the surface of the flashing screen, so that the cleaning agent can easily flow into the screen, causing a short circuit inside the LCD splicing screen, resulting in unnecessary loss.
Ninth: Develop good usage habits
Try to prevent pointing to the screen with your fingers. Because the LCD splicing screen is very delicate, and its ability to resist is relatively poor, it is so simple to add dead pixels. This is also an important reason why some users will find more and more dead pixels after using it for a period of time. This situation cannot be reversed and remedied. In addition, do not open the back cover of the LCD splicing screen when it is powered on. Even after the power is off, the remaining instant voltage is quite high. The CFL transformer in the scenery lighting assembly still has a high voltage of about 1000V.
