How to solve the aging of splicing screen and the phenomenon of flower screen

Splicing screen aging problem

This article refers to the address: http://

LCD splicing screens can easily overheat some pixels due to long hours of 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.

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.

Splicing screen flower screen problem

One: Check if the connection between the LCD splicing screen and the graphics card is loose. Poor contact can lead to "clutter" and "noisy" patterns are the most common phenomenon.

Two: Check if the graphics card is overclocked. If the graphics card is overclocked, irregular and intermittent horizontal stripes will generally appear. At this time, the overclocking range should be appropriately reduced. Note that you should first reduce the memory frequency.


Three: Check the quality of the graphics card. If there is a problem with the flower screen after replacing the graphics card, and after the first and second strokes are not effective, check whether the anti-electromagnetic interference and electromagnetic shielding quality of the graphics card pass. The specific method is to install some components that may cause electromagnetic interference as far as possible from the graphics card installation (such as the hard disk), and then see if the flower screen disappears. If it is determined that the electromagnetic shielding function of the graphics card is off, you should replace the graphics card or make a shield.

Four: Check if the resolution or refresh rate of the LCD splicing screen is set too high. The resolution of the LCD splicing screen is generally lower than that of the CRT display. If the optimal resolution recommended by the manufacturer is exceeded, the phenomenon of blooming may occur.

Five: Check if an incompatible graphics driver is installed. This situation is generally overlooked because the graphics card driver is getting faster and faster (especially NVIDIA graphics cards), and some users can't wait to install the latest version of the driver. In fact, some of the latest drivers are either beta versions or optimized for a particular graphics card or game. Using such drivers can sometimes lead to screens. Therefore, it is recommended that you use Microsoft-certified drivers as much as possible, preferably using the drivers provided by the graphics card manufacturer.

Six: If you can't solve the problem after using the above five strokes, there may be quality problems with the LCD splicing screen. In this case, please replace the other monitors for testing.
