As we all know, splicing screen has become one of the mainstream products in the display industry, and its wide application in the room is no less than the original LED, accounting for almost half of the large display screen, attracting a large number of splicing screens and related practitioners. The peripheral processing equipment of the splicing screen, such as processor, high-definition matrix, network decoding matrix, HDMI matrix, hybrid matrix and other signal switching control equipment, is the core equipment of the entire splicing large screen system, and the matrix is also an important equipment for controlling signal input and output. How do they differ in how they work and what they do? Here are the basics of how Geffen Technologies shows you the difference between a processor and a matrix:

1. Functional differences
1. The matrix is to switch the output of multiple input signals to multiple display devices, and generally speaking, the number of input signals is greater than the number of output signals. For example, if we want to monitor the signals from 100 cameras on 9 monitors at the same time, we can use the matrix to realize it, and rotate the display of different signal images through the signal switching function of the matrix. The types of matrices include VGA matrix, AV matrix, RGB matrix, DVI matrix, HDMI matrix, hybrid matrix, and so on.

2. The image processor contains the function of the matrix and the image processor is more powerful, it has all the functions of the matrix, and on this it also adds the functions of windowing, picture-in-picture, superimposed roaming, etc., and can also decode the 4-split display of the monitoring screen, for example, we have a signal on the computer that wants to be superimposed on the main screen signal to display, at this time an image processor can be realized. In addition, the splicing screen can also increase the number of boards, arbitrarily control the input and output interfaces, and support 4K conversion, which is more powerful. The difference between the splicing screen image processor and the matrix is still relatively obvious, it is obvious that the image processor is more powerful, it contains all the functions of the matrix, if we are just a small display system, there are multiple computers to input, there is no monitoring image and no special display requirements, then a matrix can be used. And if it is used for some large-scale command and dispatch center, that is, there is electricity and surveillance video signal access, then an image processor will be more suitable, and it can also realize more diversified cross-screen display function, which is not realized by the matrix.

Matrix is a signal processing equipment, it is composed of two kinds of input and output interfaces, the same input is connected to the computer, the output is connected to the splicing screen, to realize the switching and display of the signal, the purpose is more HDMI interface matrix, the number of interfaces can be infinitely expanded.
First, the function of the matrix matrix is mainly used in the splicing screen display system with multiple computer signal inputs, such as conference rooms, exhibition halls, etc., the front end has multiple computers want to display on the screen at the same time, and the back end also has a large screen with multiple splicing, at this time, the switch of computer signals can be realized through the matrix, so that the image on a certain computer is displayed on a certain splicing screen or several splicing screens. The functions of the matrix mainly include full-screen display, split-screen display, any combination of display, etc., but it cannot decode the monitoring image, and only supports computer signal input.
Second, the difference in principle

Due to the difference in working principle, the functions of the two systems are also different. The high-definition matrix can only be responsible for signal switching, and cannot process and produce effects. The large screen splicing screen processor is very powerful. It has a matrix, function, and can also realize arbitrary windowing, roaming, overlay, scene saving and rotation. It also has functions such as special effect masks, video overlays, custom logos, intelligent system detection, and multi-screen interaction. The high-definition hybrid matrix has different functions from the splicing screen processor and plays a different role in the system integration project. Users can choose and match according to their own needs, or they can control it together.
