LCD splicing screen is a large-screen product with splicing ability and can form a large-area display area. It is widely used in various large-screen demand occasions, such as conferences, exhibitions, monitoring command centers and other fields. It can realize single screen and full screen. There are multiple display methods such as, split, and cross-screen roaming. So how does the LCD splicing screen realize splicing and other functions?
1. The LCD splicing screen itself has splicing function
As an industrial-grade display, LCD splicing screen has basically the same structure as LCD TVs. The core component is an LCD panel, and there is a controller behind the panel. The main function of this controller is the splicing function, which is Multiple LCD splicing screens can be spliced into a large display, which is why it is called a splicing screen.
So, one of the reasons is because of its own structure, the controller is the main device to realize this function.

2. Control equipment
Although the LCD splicing screen has its own splicing controller, which can realize the splicing function, it is necessary to install a control device at the back end to connect the computer and the large screen. At present, the most widely used are HDMI distributors, matrixes, decoders, external image processors, etc. According to different functions and uses, the selected control equipment is different.
For example, when we spliced 9 screens, the splitter can only have one input signal, usually a 1 input 12 output splitter, connect an HDMI HD line from the computer's graphics card output to the input interface of the splitter, and then output from The interface connects 9 HDMI lines to each LCD splicing screen. This can achieve two display effects, one is that 9 screens display a large screen, and the other is that 9 screens display 9 the same screen at the same time.
The matrix is compared with the distributor in that it solves the problem of multiple computer input and can switch the display at will. The decoder is mainly used for video monitoring and display. If you need to roam the picture, you need to match an external image processor.
Three, line connection
When the technology is installed, the screen and the screen must be connected in series through a network cable, so that the connection between the screen and the screen can realize the splicing of the screen. The network cable is drawn from screen 1 to screen 2, and so on, all the LCD splicing screens are stringed together, so as to realize the connection of the computer to the distributor, and then to each screen.
The LCD splicing screen can realize the splicing function, one is that it has this kind of splicing, and the other is that it is controlled by some control equipment and lines, so splicing is also its most basic and powerful function. It can be spliced into display screens of any size according to the number of video surveillance and the size of the display area, and with the introduction of more ultra-narrow-edge splicing panels and seamless splicing screens, its application range is becoming more and more extensive.
