LCD splicing walls not only have many characteristics and advantages, but also have very convenient splicing methods. At present, there are three splicing methods on the market: external drag splicing controller, embedded and PCI plug-in.
Common LCD splicing wall splicing methods.
1、 External drag splicing controller type.
The external drag splicing controller can also be referred to as a large screen display splicing device or a TV background wall control board. The specific function of the TV background wall splicer is to distinguish a complete image data signal into N blocks, and then allocate them to N short video display modules (such as back projection modules), forming a display screen with many ordinary short video modules.
2、 Embedded.
The basic working principle of embedded splicing screens is that each splicing module has a separate video editing control module, which transmits detailed information to each module based on vectors, performs video editing separately, divides the parts that should be displayed, and displays this part of the data signal, completing the purpose of large screen splicing display. Because it is solved separately, the number of spliced modules is theoretically infinite.
3、 PCI plug-in.
The basic working principle of PCI card insertion is to use an industrial control computer and a multi screen splicing card. Firstly, a complete short video image is divided into M * N height video streams, and then this sub signal is transmitted to each matching module on the splicing building curtain wall to achieve the purpose of large screen splicing display. It can simultaneously connect various devices to achieve the functional requirements of splicing large LCD screens. Commonly referred to as external drag, this type of splicing of building curtain walls is divided into two separate parts. One part is the display part, which can be composed of general LCD splicing display modules such as LCD splicing walls; The other part is the splicing controller, whose function is to complete the display export after the screen resolution is stacked, making the display screen an image.
