Large screen matrix system and splicing screen connection system

HDFocus In indoor large-screen display system, large-screen matrix system and splicing screen are two kinds of commonly used control and display equipment, which are connected to realize an integrated display scheme . The large screen system applied to the matrix is basically an occasion where multiple computer signals need to be input and switched for signal display, such as some meeting rooms or big data platforms, etc. in these occasions, images from multiple computers need to be displayed on the big screen, while the splicing screen is just a kind of high-definition display screen. If the size and location of the screen display on the computer is reached, a large-screen matrix system is required for control and switching.

Therefore, a splicing screen display system consists of the following three parts, one is the computer signal source in the front, the other is the large-screen matrix system in the middle , and the other is the splice screen. The computer is responsible for signal input, the matrix system is responsible for signal control, and the splicing screen is responsible for display. The specific connection diagram is as follows.

In the actual connection, HDFOCUS an e ⅲ high-definition line will be drawn from the computer side and connected to the input terminal of the matrix. At the same time, the computer will be connected to the RS232 interface to realize the signal distribution and switch function setting. On the matrix output interface, several HD lines are branched off according to the number of splicing screens, which are respectively connected to the input interface of the splicing screen. Similarly, the RS232 output interface 0ut of the matrix is connected to a certain splicing screen by an RS232 control line. In this way, a connection diagram between the large-screen matrix system and the splicing screen is realized, which mainly uses the high-definition line and the command line.

In addition, we need to connect all the splicing screens in series by network cable to realize the signal synchronous input and full-screen display function, so that a computer screen can realize the function of full screen display.

With the increasingly widespread use of the splicing screen in the fields of indoor Conference, display, data analysis and other fields, at the same time, the computer of input is not one, at that time, the requirements of the large-screen ordering system can not be met by the distributor, the large-screen matrix system has become a kind of widespread use, because the signal source resolution is getting higher and higher, the traditional wCa matrix has been used very little, the EII interface matrix has become the mainstream of the market.

In the actual connection, we also need to consider the actual distance between the signal source and the large-screen matrix system and the splicing screen. For example, in some showrooms, the signal source may be in the engine room, and the distance is relatively long. In order to ensure smooth signal display, try not to transmit more than 30 meters, and we also try to place the matrix behind the splicing screen to reduce the length of the HD line.
