A complete splicing LCD large screen system consists of multiple parts, which together complete input, output, and display functions, and are widely used in video surveillance display, command and scheduling, conferences, exhibition displays, and other fields. Generally speaking, the composition of a splicing LCD large screen system includes not only the display screen, but also four major parts: the central control system, decoding platform, and input signal source.
The central control system mainly connects the display screen and input signal source. For example, in a video surveillance room, in addition to setting up a splicing LCD screen system, it is necessary to consider the number of front-end monitoring and choose a suitable decoding platform. For example, how many segments should be displayed on each screen. At this time, to ensure that all monitoring videos are displayed on the screen simultaneously, it is necessary to configure different splicing LCD screens and the number of decoding platform interfaces. Of course, it is also necessary to consider whether the brand of front-end cameras is consistent. If not, compatibility issues must be solved.
At present, the central control system mainly includes decoders, external splicing processors, etc. If only switching computer signals, there are also matrices, etc.
The signal source of a splicing LCD large screen system is nothing more than computer signals and monitoring signals, also known as input signal sources. If there are multiple computers that need to be displayed on the screen, the problem of signal switching needs to be considered. In this case, a matrix or external splicing processor can be used to solve the problem. However, if it is a video monitoring signal, a decoder must be equipped.
A complete splicing LCD large screen system, in addition to the three major parts mentioned above, also requires connecting cables, NVRs, switching devices, etc., in order to form a complete display platform. When designing a solution, we must choose a manufacturer with stronger comprehensive technical capabilities, which not only ensures product quality, but also technical capabilities and after-sales service quality.
