[ Huaqiang Security Network News ] In the large screen wall system , the damage caused by the screen is easy to have the following aspects: 
1. The crush on the surface or inside of the screen, black spots, scratches during the installation process.
2. Corrosion damage caused by special adhesives during the manufacturing process. This kind of cultural hall damage is more likely to appear on the edge of the screen, and can be seen under the white signal of 100%.
3, the screen production process is imperfect caused by the phenomenon of light leakage around the screen: the specific performance is that when the image signal is 100% full white, the screen four can see brighter highlights or a section of bright lines. It has a great influence on the visual effect.
4. The flattening effect of the large screen wall is different in the level of the production process due to the different screen types produced by various manufacturers, so the flattening effect in the whole large screen wall system is different. Excessive deformation of the screen will affect the overall effect of the large screen wall and the quality of the image. So there should be a specific indicator that can be accepted.
5, the large screen wall of the seam effect, the production and installation process is different, it will make the whole big screen wall wall seam effect has a big difference. It also produces the idea of ​​physical seams and optical seams. Whether it is physical or optical seams, (optical stitching is caused by imperfect production structure of the screen), as long as the black edge formed by the edge that the light can not reach, it should be the actual seam of the wall. The ideal seam should be a thin and even black line. At the same time, there is no phenomenon in the seams, which is caused by the imperfect process. If the seam is too large, the edge information of the image will be lost. The visual impact on the large screen wall is also large.

Circular saws are most frequently used Power Tools on woodworking. They are categorized according to their drive motor, the type of depth control they use, their cutting depth and power input. Circular saws are available in general-purpose and special versions. Typically, hand-held circular saws are mounted on a base plate.
