LCD splicing screen installation skills and steps

Introduction

　　The installation of the LCD splicing screen is not like ordinary display equipment, it is simply installed and installed. The installation of the LCD splicing screen not only needs to choose the installation site carefully, but also needs to pay attention to the light around the installation environment, and also needs to pay attention to the wiring, and there are also requirements for the frame. Now let’s talk about how to install the LCD splicing screen.

　　method/step

　　Choice of installation ground:

　　The installation ground 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 selected ground also needs to have a certain ability to bear weight. If the ground is made of ceramic tiles, it may not be able to bear its weight. Another point is that the installed ground must be anti-static.

 　Notes on 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 required, and calculate the needs of the entire project.。

Ambient Light Requirements：

　　Although the brightness of the LCD splicing screen is very high, it is still limited after all, so the surrounding light of the selected installation environment should not be too strong. If it is too strong, you may not be able to see the picture on the screen. The light that may be incident near the screen (such as a window) should be blocked if necessary, and it is best to turn off the light 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 tube lights.

　　Framework requirements:

　　In order to facilitate the maintenance of the LCD splicing screen in the future, the frame must be detachable. A gap of about 25mm is reserved between the inner edge of the outer frame and the outer edge of the panel wall. For large panel walls, a margin should be appropriately increased according to the number of columns. In addition, in order to enter the box for later maintenance, the maintenance channel should not be less than 1.2m wide in principle. It is advisable to press the edge of the screen by 3-5mm for the detachable side strips, and fix the detachable side strips after the cabinet and the screen are completely installed in place.

　　ventilation requirements：

　　In the maintenance passage, 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 from the LCD splicing wall as possible (about 1m is better), and the wind from the air outlet should not be blown directly to the cabinet, so as to avoid damage to the screen caused by uneven cooling and heating.

　　At the LCD splicing construction site, the installation and debugging should judge the cause according to the phenomenon reflected by the fault. It is necessary to focus on checking the synchronization interface and transmission cable of the equipment, and comparing 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 for testing, or add equipment such as a signal amplifier. If the focus is not ideal, the display terminal can be adjusted. Facing the emergence of problems, we must first learn to analyze in order to better solve the root cause of the problem. Through powerful analysis, the inspection time can be shortened. These methods are some methods and techniques for debugging after installation. The installers must be proficient and good. Only professional people can do professional things.
