Design LCD Video Wall splicing screen display scheme

At present, the large-screen TV wall splice screen using LCD technology has become the main product of the indoor large-screen system. It can connect the computer with the video monitoring signal to realize a variety of large-screen display functions, such as multi-computer display on the same screen and remote transmission display of multi-channel monitoring picture, and can run continuously. However, according to the user's use and specific display needs, the design scheme of each LCD Video Wall splicing screen display system is different, which should take into account the type of signal source, cost budget, the size of installation space and other factors. But no matter what kind of situation a comprehensive display scheme should include three components, respectively is the large screen display terminal, control processing system and signal source, some objective factors will directly affect the choice of these three parts of the hardware.

Therefore, when we design splicing screen display scheme of large screen TV wall, the first thing is to consider objective factors, and then consider the comprehensive demand, so as to provide a more reasonable splicing way and control system. For example, the length and height of the installation space will directly determine how many rows and columns the splicing screen is used. Whether the wall can bear weight will affect the installation mode of the splicing screen. At the same time, the cost budget of the user will also affect the size of the splicing screen of the large screen TV wall and the choice of splicing joint.

First of all, we need to confirm the signal source at the front end. In most cases, LCD Video Wall patchwork screen system mainly displays monitoring signals and computer signals. If it is a large screen in some monitoring rooms or command centers, dozens or hundreds of monitoring signals may be connected at the same time, and some are still remote transmission, multi-level management, etc. At this time, it is necessary to decide the transmission mode according to the transmission distance and the number of monitoring, whether to use network cable or optical fiber transmission, whether to manage and share signals in layers, so as to realize distributed management. If the large-screen TV wall splice screen is connected to the computer signal, which is generally applied in the meeting room or data analysis display occasions, then only the distance between signal switching and transmission connection needs to be considered.

Secondly, there is also a central control processing system between the signal source and the LCD Video Wall splicing screen, which is mainly used for signal processing. The front end is connected with the signal source, and the back end is connected with the large screen. It is equivalent to the brain of the large screen display system, which is used to schedule and switch the signal display, and realize various display functions. If the input display is a video surveillance signal, it can be controlled by decoder and external splicing image processor. The difference between them is that the decoder has stronger codec function, which can realize the maximum 32 channel picture segmentation in a single screen and ensure that more monitoring images can be displayed on the screen at the same time. The advantage of image processor is that it can realize cross-screen roaming display with Windows. It is often used in some monitoring, command and dispatching situations. If it is a large screen TV wall splicing screen connected to the computer, then it is necessary to see the number of input computer to match the corresponding control equipment, currently used more is a splitter and matrix, if it is a computer, then you can use a splitter, multiple computer input case according to the number of computers and splicing screen number to choose a corresponding interface matrix.

Finally, the core of an LCD Video Wall splicing screen is the splicing display end, which is composed of industrial grade LCD panels. It is a large splicing display screen, which can adopt the splicing way of horizontal screen, vertical screen and arc screen to centrally display various signals on it. Generally, the size of the large screen splicing screen is about 55 inches, which can be used in the splicing forms of 2*2, 3*3, 4*5, etc., and fixed through the installation methods of bracket, cabinet TV wall, etc., to form a visual large screen display wall.When designing the LCD Video Wall splicing screen display scheme, it is necessary to consider not only the type of signal source, but also the detailed factors such as how to connect and control the computer and the distance between the screen and the signal source, which will affect the installation details. In short, the establishment of the scheme needs to communicate with the user about the detailed use requirements, and consider objective factors, and match the suitable central control system. Realize the signal distribution and display function on the large screen TV wall splicing screen.
