　　Simply put, LCD splicing screen is used as a whole screen for display. We understand it as the backend, where the signal source in a computer USB drive or other device is the output, which can be understood as the front-end. If the front-end image wants to be displayed on the back-end screen, it needs to be achieved through an intermediate device.

　　Intermediate devices can be roughly divided into four types: allocators, matrices, processors, and decoding matrices.

　　1. The distributor function is relatively simple, with one in and multiple out, and can only be displayed as a whole screen. If we only have one computer input to the splicing screen and only need to display one function in full screen, then we can use a one in multiple out distributor.

　　2. The matrix has rich functions, with multiple inputs and outputs, and can be displayed in split screens. If it is multiple input computers and multiple screens need to be displayed simultaneously on the splicing screen, a matrix is needed. It can achieve synchronous switching of display among multiple computers on the basis of the distributor, and can control several screens to display one screen at will.

　　3. The processor is powerful and can achieve functions such as window opening, roaming, and stacking on the basis of the matrix.

　　4. The decoding matrix, as the name suggests, is the decoding of video surveillance images, which can not only be concatenated and displayed, but also segmented and displayed.
