Image splicing processor is also called TV wall controller, TV wall splicer, display wall splicer, splicing wall controller, multi screen processor, multi screen splicing processor, display wall splicer, digital splicing processor, multi screen image processor and display wall processor. Its main function is to divide a complete image signal into n blocks and distribute it to n video display units, A large screen dynamic image display screen is composed of several ordinary video units, which can support the simultaneous access of multiple video devices.With the increasing dependence on splicing processor in the process of using splicing screen, the advantages of splicing processor can affect the display effect of splicing screen. In order to display as much information as possible at the same time, the scale of large screen splicing in various fields is increasing. As one of the core equipment of large screen splicing, the importance of large screen splicing processor is also highlighted with the expansion of splicing market scale.

In the large screen splicing industry, the strategic value of splicing processor products is second only to display unit. If a large screen display system is regarded as a computer, then the splicing processor is the brain organ CPU of the whole large screen system. All the information in the whole system is given to it through various channels, and then it presents the processing results to the display part.

In the competition from display technology to splicing processing technology, the shift of competition focus of large screen splicing manufacturers has also made significant changes in the main players of the processor industry. Many large screen splicing manufacturers also provide splicing processors or strengthen their investment in splicing processors; In addition, in order to meet the needs of different industries or gain more initiative, some manufacturers began to set foot in more product lines, not only providing DLP splicing and processor products, but also involved in LCD splicing and processor, LED large screen and processing products; specializing in processor R & D and providing all types of processor products nearly meeting market demand.

　　
Today, processor not only has many types of products and technologies, but also is engaged in complex enterprises. The number of cross industry, market and technology mixed competition enterprises is increasing.For manufacturers specializing in video signal processing, the development of splicing processor is the basis for the survival of enterprises; for large screen manufacturers, the development of splicing processor is to strengthen the control of core technology of large screen, and is an important way to create differentiation; For the related IT manufacturers and peripheral manufacturers, the processor is like a bridge to the large screen display field. With the core position of splicing processor in the large screen industry, more IT products can be continuously pushed to the large screen display field, opening a new "supermarket". Therefore, the splicing processor is of great strategic significance to both the enterprises in the industry and the surrounding enterprises.
