The LCD splicing screen installation project has many details that need attention, but from a macro perspective, after we choose a suitable splicing screen solution, we can control the following five points to have a good control of the entire project. As far as the product is concerned, not only can the product run well after the purchase. For example, if the screen is too heavy and the environment is not evaluated, problems such as offset may occur after installation.

(1) The choice of installation ground for LCD splicing screen

 multi-screen

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 choice of surface also needs to have a certain ability to bear weight. If the wall is tiled, it may not be able to bear its weight. Another point is that the mounting surface must be anti-static.

(2) Precautions for LCD splicing screen wiring

When installing the LCD splicing screen, pay attention to distinguishing its power line and signal line 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 the various lines needed, and calculate the needs of the entire project.

(3) Ambient light requirements for LCD splicing screens

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

(4) LCD splicing screen frame requirements

In order to facilitate the maintenance of the LCD splicing screen in the future, the frame edging must be a detachable edging. A gap of about 25mm is reserved between the inner edge of the outer frame and the outer edge of the splicing wall. For large-scale splicing walls, the margin should 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 side strips should preferably be pressed 3-5mm from the edge of the screen. After the cabinet and the screen are fully installed in place, the detachable side strips can be fixed.

(5) Ventilation requirements for LCD splicing screens

In the maintenance passage, air conditioners or air outlets must be installed to ensure that the equipment is well ventilated. The location of the air outlet should be as far away as possible from the LCD splicing wall (about 1m is better), and the air from the air outlet should not be blown directly against the cabinet to avoid damage to the screen due to uneven heating and cooling.

 In addition to these 5 points, in the LCD splicing construction site, the installation and debugging should be based on the phenomenon reflected by the fault to determine the cause, and the synchronization interface and transmission cable of the equipment should be checked, and the synchronization frequency range of the signal source and the display terminal should be compared. If the image has ghosting, check whether the transmission cable is too long or too thin. The solution is to change the cable to test or add a signal amplifier and other equipment. If the focus is not ideal, you can adjust the display terminal. Facing the emergence of problems, we must first learn to analyze, so as to better solve the root cause of the problem. Through strong analysis, the inspection time can be shortened.
