  Installation method diagram and wiring method of LCD splicing screen
1、 What is LCD splicing screen
LCD splicing screen can not only be used as a display alone, but also be spliced into a super large screen
According to different use requirements, it can realize the functions of variable large screen: single screen split display, single screen separate display, arbitrary combination display, full screen LCD splicing, double splicing LCD splicing, vertical screen display, optional compensation or covering of image frame, support roaming, scaling and stretching of digital signals, cross screen display, setting and operation of various display plans, and real-time processing of Full HD signals

 
2、 Installation method of LCD splicing screen
1
Selection of ground splicing LCD screen installation
The installation surface of LCD splicing screen should be flat, because the whole system of LCD splicing screen is relatively large in both volume and weight
The selection surface also needs to have a certain weight bearing capacity
If the wall is made of ceramic tiles, it may not be able to bear its weight
Another point is that the mounting surface should be anti-static

2
Precautions for LCD splicing screen wiring
When installing LCD splicing screen, pay attention to distinguish its power line and signal line during wiring, and install it in different places to avoid interference
In addition, the length and specifications of various lines required shall be calculated according to the screen size and installation position of the whole project, and the needs of the whole project shall be calculated

3
Requirements for ambient light of LCD splicing screen
Although the brightness of LCD splicing screen is very high, it is still limited after all, so the light around the installation environment should not 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 windows) shall be blocked if necessary
At the same time, it is best to turn off the light when the equipment is running to ensure the normal operation of the equipment
Do not install a lamp directly in front of the screen, just install a barrel lamp

4
LCD splicing screen frame requirements
In order to facilitate the maintenance of LCD splicing screen in the future, the frame edge must be removable
The inner edge of the outer frame shall reserve a gap of about 25mm from the outer edge of the wall, and the allowance shall be appropriately increased according to the number of columns for large wall
In addition, in order to enter the box for maintenance in the later stage, the maintenance channel shall not be less than 1
2m wide in principle
The removable edge strip should be pressed 3-5mm to the edge of the screen
After the box and the screen are completely installed in place, the removable edge strip can be fixed finally

5
LCD splicing ventilation requirements
In the maintenance channel, air conditioner or air outlet must be installed to ensure good ventilation of the equipment
The air outlet shall be located as far away from the LCD splicing wall as possible (about 1m is better), and the air at the air outlet shall not be blown directly against the box to avoid damage caused by uneven cold and heat of the screen
　　
Here are the installation methods and steps of LCD splicing screen
At the construction site of LCD splicing, the installation and commissioning shall judge the cause according to the phenomenon reflected by the fault, and focus on the synchronous interface and transmission cable of the equipment, as well as the synchronous frequency range of signal source and display terminal
If the image has ghosting, check whether the transmission cable is too long or too thin
The solution is to change the line for test, or add equipment such as signal amplifier
If the focus is not ideal, the display terminal can be adjusted
In the face of problems, we must first learn to analyze in order to better solve the root causes of problems
Through strong analysis, we can shorten the inspection time

3、 LCD splicing screen wiring method
First: link of LCD splicing box
The connection of LCD splicing screen is firstly the connection of hardware
Those who know LCD splicing screen well know that the splicing screen is composed of several small screens, and there are many signal interfaces behind the splicing screen
Such as HDMI, DVI, VGA, RGB, component and terminal, and the VGA interface is connected to the computer
Usually we just need to connect the computer to the VGA interface
Because under normal circumstances, LCD splicing screen is less used for single connection
Therefore, if the whole LCD splicing wall is connected, we only need to connect the line to the splicing processor
After the splicing processor is connected in series, we only need to escort one signal access

 
Second: matrix or Controller Link
In the scheme of large screen splicing curtain wall, the input signal or output signal may be different, or it is required to display multi-channel signal input or output
At this time, we must equip the matrix
The more rich the matrix interface is, we just need to find the response interface
If matrix signal access is involved, it is recommended to ask professional technicians to install it

The above are the two parts of LCD splicing screen wiring
The splicing screen itself is connected to the body, and the splicing screen is connected to the processor
If you don't know how to connect the splicing screen for the first time, you can consult the technical personnel of Maijun technology, the manufacturer of LCD splicing screen, for corresponding technical guidance
