Information display technology of spliced large screen

The invention provides an information display technology of a spliced large screen. The technology comprises a signal source, a large screen controller, a local display terminal and a spliced large screen. The method comprises the following steps: (a) acquiring signals of a computer terminal and a video pick-up terminal; (b) synthesizing the acquired multi-channel signals into one-channel signals by utilizing the large screen controller; (c) and processing and outputting the signals as RGB or DVI signals, wherein the output signals in one channel are transmitted to the spliced large screen to be displayed through a VGA or DVI data line, and the output signals in the other channel are converted into GVA signals and then transmitted to the local display terminal to be displayed. In the invention, multi-channel signals from the signal source are synthesized into one-channel signals by utilizing the large screen controller, and special control software is utilized to dynamically adjust the displayed information of the signal source, thereby displaying information of the spliced large screen at the local display terminal in real time and ensuring the resolution and real-time performance of the displayed information.
