LCD splicing screen and matrix: Qunmao Display Technology takes you to explore the inner world of large display screens

  Qunmao Display Technology Co., Ltd. focuses on the production and application of LCD splicing screens, which has been widely used in 

government agencies, shopping malls and other places. However, many people are not clear about how these large display screens are 

made. This article will explain the selection and matching of LCD splicing screens and matrices, and explain their role in the entire

 display system.

1. What is a splicing screen matrix?

The splicing screen matrix is a matrix device specially used for splicing screen projects. It plays the role of a signal processor and a

 video switcher to achieve the management of input and output signals, so that the signal source can be freely switched and displayed 

on the large screen.

2. What are the types of matrices?

In the field of splicing screens, the types of matrices are usually distinguished according to the signal interface, including HDMI, DVI, VGA,

BNC, SDI and mixed types of matrices.

3. How to match the matrix with the splicing screen?

When choosing a matrix, care should be taken to avoid excessive functions. Generally speaking, the number of output ports should be

 greater than or equal to the number of splicing screens, and the number of input ports should be greater than or equal to the number 

of signal sources. For example, if there are 10 computer signals to be displayed on a 3x4 spliced large screen, then select a 12-input 

12-output matrix, without the need to select 16-input 16-output.

4. How to connect the spliced screen to the matrix?

Connect the signal source output to the input port of the matrix;

Connect the output port of the matrix to each screen of the spliced screen;

Each screen in the spliced screen is connected in series through the RS-232 line, connected to the last screen, and then connected to

 the control computer;

Perform signal compression on the display device;

Control the matrix through the splicing processor software.

5. What are the functions and features of the matrix?

Modern matrices have many functions, such as supporting WEB/APP control of mobile phones or tablets with Android and iOS systems, 

4K 30HZ input and output, visual buttons, centralized control functions, etc.

6. What are the characteristics of the matrix?

Modern matrices have features such as support for HDMI 1.4a protocol version, Deep Color support, and support for any signal source

 to be displayed on multiple displays at the same time.

7. Which spliced screens need to use matrices?

Spliced screens are widely used in conference rooms, monitoring rooms, exhibition halls and other scenes, and the matrix plays an

 important role in them. The above is some introduction and explanation of LCD splicing screens and matrices, I hope it will be helpful 

to you. If you have any questions or needs, please feel free to contact us, we will wholeheartedly provide you with solutions.
