A complete security monitoring system, video conference system, or exhibition display system is composed of multiple devices. Although LCD splicing screen is also an important terminal display device, other external devices are also indispensable. Strictly speaking, what external devices are needed for a LCD splicing system depends on the actual situation of the project. Generally, what external devices are needed for splicing LCD screens?
1： Peripheral equipment
Peripheral equipment includes signal source desktop access system, cables, connectors, cabinets, power supply parts, etc;
2： Centralized control equipment
There are many types of devices in the large screen LCD splicing display system, including a large number of LCD splicing screens, matrices, and signal sources. The central centralized control equipment can better help you quickly process signal selection and switching, facilitate and quickly control the equipment operation process, and quickly improve work efficiency and accuracy.
3： Signal processing equipment
Signal processing equipment includes the conversion of signal source types, signal switching, signal amplification and transmission, etc., which is very important for the display of large LCD splicing screens.

4： The LCD splicing processor mainly determines the content and speed of the large screen display. The quality of the processor directly affects the processing speed of the signal source, the clarity of the image, the quality of soft edge fusion, and so on. It plays an important role in LCD splicing screens.
5： LCD splicing screen
The screen provides the audience with the most intuitive visual impact, and the choice of LCD splicing screen is therefore very important. Only by ensuring that the seams of the screen are narrower can the display be more perfect.
