PP PP is a hollow ball material injection molding, mold our independent
research and development, efficient and practical.Pp packing is the exhaust gas Purification Tower in will be used for
packing, generally placed in the tower in the mist purification device layer or
washing layer.Mainly from the filter, neutralization
and water mist in the role of the company's own production of PP hollow
spheres, spherical shape, there are 12 leaves. A large number of production,
cheap and good quality.

When the static electricity around the work environment of the LCD splicing screen is relatively large, it may cause certain interference to the video signal, and may also cause damage to the chip at the interface of the splicing system, and may even seriously affect the display effect of the large screen. However, static electricity is ubiquitous under the laws of nature. Especially in the presence of high-voltage electricity or a place with a strong magnetic field and friction, the electrostatic phenomenon will be serious. There is a certain potential difference between the ground and the earth. This is also a kind of static electricity. However, we cannot completely prevent it from being produced. In the debugging of LCD large screens, it is often disturbed by static electricity. There are often lines in the screen. We can analyze the causes and phenomena of static electricity, and adopt appropriate solutions. Here, the well-known brand of liquid crystal splicing is available. Some suggestions for minimizing electrostatic interference on the LCD panel during installation by the installer:
1. Grounding: It is the direct discharge of static electricity through the wire connection to the earth. This is the most direct and effective method for preventing static electricity. For conductors, grounding methods are usually used. The main cabinet, DID LCD splicing screens each with a wire connected to the ground.
2. The line and the line are separated: The line and the line are separated and the VGA line and the power line are separated. We all know that the VGA cable we generally use is not shielded, and the unshielded VGA cable and the power cable are likely to cause static interference.
3. Insulation: It is to stick the insulation tape to the DID liquid crystal splicing screen and the metal and power connection to prevent static electricity.
Static electricity is one of our common faults, and we often encounter reflective interference problems that make the LCD splicing screen image appear vague and unclear. The emperor said that in the use of LCD video wall will encounter some faults are not The most important thing to avoid is that we can find problems and solve problems before we can achieve breakthrough development.

LCD splicing products are favored by users because of their unmatched high-definition, high-brightness, high-contrast, and low-power image quality that cannot be matched by other splicing screens. In recent years, the limitations of high-end applications have been broken, and a wide range of applications have been segmented in various industries. The field spans power, bars, shopping malls and other places. With the use of liquid crystal splicing environment, diversified users often encounter some problems in the use of LCD splicing screens, the most common is to encounter static interference.
