Installation Skills And Precautions For LCD Video Wall

What are the installation skills and precautions for LCD video wall?

Many people have such questions. In fact, the installation of an LCD video wall is not the same as ordinary display equipment. It is just installed as soon as it is placed. The installation of an LCD video wall not only needs to carefully choose the installation site, but also pay attention to the light around the installation environment, pay attention to wiring, and also have requirements for the frame, so what are the installation skills and precautions of LCD video wall?

First, the choice of installation ground

The installation ground of the LCD video wall should be flat because the entire system of the LCD video wall is relatively large in size and weight. The selected floor needs to have a certain ability to bear weight. If the floor is a tile, it may not be able to bear its weight. Another point is to install the ground to be able to prevent static electricity.

Second, wiring precautions

When installing the LCD video wall, pay attention to distinguishing its power line and signal line when wiring, and installing them in different places to avoid interference. In addition, according to the screen size and installation position of the entire project, calculate the length and specifications of various lines required, and calculate the needs of the entire project.

Third, ambient light requirements

Although the brightness of the LCD video wall is very high, it is still limited after all. Therefore, when choosing the installation environment, the surrounding light should not be too strong. If it is too strong, it may not be able to see the picture on the screen. The light (such as windows) that may be injected near the screen should be blocked if necessary, and the lights should be turned off when the device is running to ensure the normal operation of the device. Do not install lights directly in front of the screen, just install down lights.

Fourth, the frame requirements

In order to facilitate the maintenance of the LCD video wall in the future, the frame wrapping must be detachable wrapping. A gap of about 25 mm is reserved between the inner edge of the outer frame and the outer edge of the video wall. For large video walls, the margin should be appropriately increased according to the number of columns. In addition, in order to enter the box maintenance later, the maintenance channel is not less than 1.2 m wide in principle. The detachable side strip should be pressed against the edge of the screen by 3-5 mm. After the box body and the screen are completely installed in place, the detachable side strip is finally fixed.

Fifth, ventilation requirements

In the maintenance channel, air conditioners or air outlets must be installed to ensure good ventilation of the equipment. The position of the air outlet should be as far away as possible from the LCD video wall (about 1 m is better), and the wind from the air outlet should not blow directly against the box, so as to avoid damage to the screen due to uneven heating and cooling.

At the LCD video wall installation construction site, it is necessary to judge the cause according to the phenomenon reflected by the fault before installation and debugging. It is necessary to focus on checking the synchronization interface and transmission cable of the equipment, as well as the synchronization frequency range of the signal source and the display terminal. If the image has ghosting, check whether the transmission cable is too long or too thin, the solution is to change the cable test or add equipment such as signal amplifiers. If the focus is not ideal, the display terminal can be adjusted. Faced with the emergence of problems, we must first learn to analyze, in order to better solve the root cause of the problem, and through strong analysis, we can shorten the inspection time. These are some methods and skills for post-installation debugging. The installer must be very skilled. Only professional people can do professional things. I hope the above sharing will be helpful to you in front of the screen.
