LCD splicing screen installation method

LCD splicing screen installation method:

1. Selection of installation ground

The installation surface of the LCD splicing screen should be flat, because the entire system of the LCD splicing screen is relatively large in terms of volume and weight. The selection surface also needs to have a certain ability to bear the weight. If the wall is a tile, it may not be able to bear its weight. Another point is that the mounting surface must be anti-static.

2. Precautions for wiring

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

3. Ambient light requirements

Although the brightness of the LCD splicing screen is very high, it is still limited after all, so the light around the installation environment cannot be too strong. If it is too strong, you may not see the picture on the screen. Light that may be incident near the screen (such as a window) should be blocked if necessary, and the lights can be turned off when the device is running to ensure the normal operation of the device. Do not install a lamp directly in front of the screen, just install a downlight.

4. Framework requirements

In order to facilitate the maintenance of the LCD splicing screen in the future, the frame wrapping must be removable. The inner edge of the outer frame is about 25mm away from the outer edge of the wall, and the large-scale wall should also be appropriately increased according to the number of columns. In addition, in order to enter the cabinet for maintenance later, the maintenance channel is in principle not less than 1.2m wide. The detachable edge strip is suitable for pressing the edge of the screen 3-5mm. After the cabinet and the screen are fully installed, the detachable edge strip is finally fixed.

5. Ventilation requirements

In the maintenance aisle, an air conditioner or an air outlet must be installed to ensure good ventilation of the equipment. The location of the air outlet should be as far as possible away from the LCD splicing wall (about 1m is better), and the wind of the air outlet should not be directly blown against the cabinet, so as to avoid damage to the screen due to uneven heat.

The installation method and steps of the LCD splicing screen are shared here. At the LCD splicing construction site, the installation and commissioning should judge the cause according to the phenomenon reflected by the fault, and the focus should be on checking the synchronization interface and transmission cable of the device, and comparing the signal source and the display terminal. Synchronous frequency range. If the image has ghost images, 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, you can adjust the display terminal. In the face of the emergence of problems, we must first learn to analyze in order to better solve the root cause of the problem. Through strong analysis, the inspection time can be shortened.
