Why does the LCD screen splicing after a period of use, will there be color difference?

Whether it is LCD splicing or DLP splicing, the device will produce color attenuation after a period of use, that is, chromatic aberration. This is related to the source of illumination of the device itself. However, the difference is that the attenuation of the liquid crystal is irreversible, and there are not many ways to adjust the color of the liquid crystal device, but its attenuation does not occur frequently; the majority of the color difference of the DLP occurs because the bulb is used for a long time, and the bulb can be replaced by To adjust.

Why is the corner of the LCD screen round? Why not make a right angle so that the seam is not smaller?

After a lot of experiments, we found that after the liquid crystal is lit, it will continue to heat up during continuous use. When the heat is too high and the temperature is too high, the corners of the liquid crystal will expand. If a right angle is used, the cross stitch will be generated. Squeeze, which may cause the LCD panel to break.

The LCD screen is very easy to drop dust or fingerprints during long-term use. How should it be maintained?

First of all, the large screen should not be exposed to direct sunlight for a long time, and away from the location of humidity, high temperature, strong dust; secondly, when cleaning, do not wipe the screen surface with any alkaline solution or chemical solution; the medium used It is best to use 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 chemical solutions such as alcohol. Finally, minimize the screen. move.

What should I do if the LCD screen appears?

1 Check if the connection between the LCD splicing screen and the graphics card is loose. Poor contact can lead to "clutter" and "noise" phenomena.

2 Check if the graphics card is overclocked. If the graphics card is over-clocked, there will be irregular stripes in the DID splicing screen. At this time, the overclocking range should be appropriately reduced. Note that you should first reduce the memory frequency.

3 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. Move some components that may cause electromagnetic interference as far as possible from the graphics card (such as the hard disk), and then see if the 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.

4 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.

5 Check if an incompatible graphics card driver is installed. This situation is generally easy to ignore. 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.

How to avoid aging of splicing screen?

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". Especially when working continuously for more than 96 hours at full load, it will accelerate its aging, and even burn out when it is severe. Therefore, it is best to use it intermittently for a while, or to change the content of the screen at different time intervals, or to operate it in screen saver mode for a while. This can not only delay the aging of the LCD screen, but also Avoid hardware damage.

In addition, the liquid crystal display screen has poor impact resistance. There are many precision glass components and electrical components inside. Ultra-narrow-edge LCD splicing can cause damage to the screen and other related components once it is strongly impacted. So be sure to avoid strong shocks. At the same time, pay attention not to put pressure on the surface of the LCD screen.
