In the splicing screen control system, matrices, processors, and controllers are commonly used. However, there are still significant differences between splicing screen matrices and splicing screen processors and controllers.The devices used for LCD or LED in different applications are also different. However, it is basically only necessary to choose among these devices, which are mostly used in LCD splicing screen display systems, and the signal source is mainly computer signals, The choice of which product to use mainly depends on objective factors such as the display purpose and the category and quantity of signal sources.
The splicing screen matrix, also known as high-definition matrix, usually uses DI interface input and output, so the EDI matrix is currently mainly used in the industry. Its input and output interfaces are more than 4, supporting multiple computer inputs and switching, and simultaneously outputting to multiple splicing screens for display, achieving signal control and switching functions. It is mainly used for connecting computer signal sources at the front end and connecting splicing screens at the back end, It is a control device mainly used in LCD splicing screen systems.

And the splicing screen processor, also known as an image processor or external splicing processor, is a more powerful central processing device. It adds more diverse image processing functions on top of the matrix function, such as being able to connect to multiple computer signals and switch, and can also achieve functions such as cross screen, roaming, segmentation, stacking, and picture in picture, which is equivalent to its more comprehensive functions, This is the biggest difference between the splicing screen processor and the splicing screen matrix. So in some large-scale command and dispatch centers and other splicing screen display projects, users have multiple computer signals that need to be switched, and also need functions such as roaming and stacking. The use of splicing screen processors is very widespread.

The splicing screen controller mainly refers to the control box behind the splicing screen, which is not a separate device. It is usually integrated with the panel of the splicing screen, and is mainly responsible for the input of power and signal. The power first passes through the controller before entering the splicing screen, and the signal source is also the same because the splicing screen is only responsible for display, and controlling the splicing between various splicing screens still needs to be achieved through the controller. However, generally, when selling products, splicing screen manufacturers integrate the splicing screen and controller, as it involves compatibility and ensures the normal input and control of signals.
So, the difference between the splicing screen matrix and the splicing screen processor is mainly in terms of functionality. The matrix is only used in L-splicing screen systems where the front-end input signal source is multiple computers, responsible for signal switching display, and can achieve both single screen and full screen display effects. The splicing screen processor has stronger functions, which can be used in both LCD splicing screens and LD splicing screen display systems. It can achieve the processing and distribution of monitoring signals and computer signals, and can achieve a wider range of display functions, meeting the needs of large-scale monitoring command and data display systems. So their differences are quite obvious. In addition, the splicing screen matrix and splicing screen controller are completely different products. The former is responsible for signal switching and display, while the controller is a part of the splicing screen.
