The realization of large screen display function is undoubtedly the main function of LCD large screen system. By splicing multiple LCD screens, it can achieve a larger size and larger display area. This is the primary and largest function of LCD large screen system. At the same time, in terms of specific display functions, through some control devices, it can also achieve many display functions. For example, through matrices, multiple signals can be displayed simultaneously, enabling signal source switching and allocation. Through decoding platforms, monitoring images can be segmented and displayed. Through external image processors, functions such as cross screen stacking and roaming can also be achieved.
There are two main signal sources for the application of LCD large screen systems. One is to display monitoring video signals, and the other is to display computer signals. Some also connect to the set-top box signal source of the TV, video conference signal source, etc. However, most of them are based on monitoring signals and computer signals. For example, some monitoring rooms and command centers need to display the images captured by the front-end video surveillance camera in real-time on the LCD large screen system. In some conference rooms and exhibition halls, signals are often placed on computers to display PPT documents or webpage content in real-time.
As the backend display device, the LCD large screen system needs to be jointly installed with the signal source and control equipment to complete the entire system construction. Firstly, after installation, it needs to be debugged to ensure that the stitching is reasonable and not too wide, which will affect the viewing effect and avoid mutual compression. After connecting the hardware, the next control needs to be on the control computer. At this time, the large screen software needs to be installed and connected to the decoder software to achieve control functions of the image, such as signal switching and image segmentation.
