A set of detailed LCD splicing wall should include the following parts:
Patchwork modules for displaying images after Z: LCD splicing wall screen, DLP rear projection module, PDP low temperature plasma LCD splicing screen, etc.
The support frame used to fix the patchwork module: Generally, it is produced by the supporting facilities of the manufacturer that shows the patchwork module. Since only the manufacturer itself knows how its products are fixed and installed, it is a large-scale patchwork system. Software, it is necessary to have a high-efficiency and high-reliability main chamber support frame
The splicing processor used to complete the data signal connection solution and output to the patchwork module: Generally, it is a pure hardware configuration splicing processor based on the FPGA architecture, which can complete up to hundreds of ultra-clear, 4k high-definition data signal input and output; naturally also There are low-cost X86 architecture system software based on multi-screen graphics cards. The disadvantage is that if you want to connect a large number of other data signals (such as from DVD, surveillance cameras), the X86 architecture will be more laborious.
Transmission dedicated video cable: DVI, HDMI, SDI and other high-quality cables that conform to the data signal file format. If the quality of the selected cable is not good, it is likely to cause abnormal phenomena such as noise, poor signal, and screen flicker.
Generally, a computer must be equipped to install the management system software of the LCD splicing screen and the patchwork device: operating the power switch of the LCD splicing screen, the emergency plan of the patchwork device, reasonable layout of dialog boxes, data signal conversion, etc. The mobile phone software is produced by the supporting facilities of the manufacturer that produces the splicing processor
Stable power supply system: The overall output power of the patchwork system software is relatively large, and the instantaneous current when starting up is very high. To prevent abnormal damage caused by the surge system, it is not possible to switch the power immediately according to the one-time trip method, so it exceeds Fortunately, the system software of 15 display screens must also automatically switch the power supply in sequence (that is, a group of groups of successively open administrative organs). Naturally, if it is more cost-effective, you can also use manpower to open the power strips one by one.

LCD splicing wall module, wall-mounted or floor-standing support frame/server cabinet, embedded/external splicing processor, regulator (drainage matrix), cable (VGA cable, network cable, RS232 cable), etc. LCD splicing screen electrode connection Line, display monitor software
A detailed security monitoring system system software is composed of a variety of machinery and equipment, LCD splicing wall as a terminal device display system, although it is also one of the key machinery and equipment, other external equipment is also indispensable, but strict In a sense, a large-screen splicing system software needs to determine what external equipment is required based on the specific conditions of the new project. Under normal circumstances, what external equipment is required to piece together the LCD?
One, set up
The configuration includes the video signal desktop connection system software, cables, connectors, server cabinets, and part of the switching power supply;
2. Centralized control system machinery and equipment
There are many types of equipment in the LCD splicing wall display equipment. The total number of LCD splicing walls, the total number of drainage matrices, and the total number of video signals are relatively large. The central centralized control system machinery and equipment can help you quickly solve the data signal selection and follow-up. Conversion, time-saving and labor-saving control system operation process, quickly improve work efficiency and accuracy.
3. Signal analysis equipment
The signal analysis equipment includes the conversion of video signal types, the conversion of data signals, the enlargement and transmission of data signals, which are very critical for the information displayed on the LCD splicing wall interface of the display screen.
Four, large screen splicing CPU
Large-screen splicing CPU key decision The content and rate of the information displayed on the display interface, the quality of the CPU, will immediately endanger the response speed of the video signal, the picture quality of the interface, and the quality of the soft edge combination. It has the LCD splicing wall The key function.
Five, LCD splicing wall
The display screen gives the audience a vivid visual impact, so the choice of LCD splicing wall is very critical. Only by ensuring that the seams of the display screen are narrower can the information displayed on the interface be more extreme.
Six, support frame
According to the customer's on-site survey, the installation method of the LCD splicing wall is clarified, that is, which support frame should be used for hanging the screen. Shenzhen Siyuan Video Technology Co., Ltd. strongly recommends three support frames at this stage: wall-mounted support frame and vertical support frame , Server cabinet type support frame.
