As an all-hardware DPS architecture product, the splicing processor has flexible modular processing to support input of various interfaces and types of signal sources.

It can not only support multi-window various types of signals on a single screen for superposition, roaming, window display, support 4K ultra-high-definition signal acquisition, but also manage several groups of splicing walls at the same time, sharing input signal source between splicing walls, output without interference, you can set different resolutions, adjust colors and other parameters.

In addition, the image processor also allows the user to preview all input signals in real-time on the PC and mobile control software, allowing for a more intuitive selection of the source of the signal to be operated. At the same time, you can view the real-time echo image of the large screen in the interface, improve the operator's work efficiency and prevent misoperation.

It also has an integrated central control serial port control interface that can forward RS232, RS485, DMX512 type commands, control projectors, large screen switches, and screen lifts.

The signal processing equipment needs to be matched according to the actual situation.


The distributor switches the input of one signal to the multi-channel signal, so that the single or multiple screens of the LCD splicing wall display what you want to show, which is mostly used in the exhibition of the shopping mall or in the exhibition hall of a public place such as a hotel company, and can realize the announcement information and display the company culture. Or the effect of promotion.


Compared with the distributor, the advantage of the matrix is that multiple signals can be output to multiple ports, so that the video wall can display multiple pictures at the same time, so that the user can view the picture at the same time, get the information quickly and promptly, and use it for traffic, security areas such as fire protection or monitoring companies.

External splicing processor

On the basis of the matrix, the external splicing processor can realize the functions of roaming superp-osition, picture-in-picture, picture-drawing, multi-video window division, splicing, arbitrary drag size, letter superposition and the like. It can be used in the security field of government, fire protection, public security and other industries, and has 7*24 hours weather adaptability.


Most of the frames of the splicing wall are three types: wall-mounted, stereo frame and floor cabinet. The specific choice needs to be selected according to the actual situation and the needs of the customer.

Wall-mounting is quick and easy to install, but considering the load-bearing capacity of the wall, this method is only suitable for small screens. The stereo frame has higher requirements on the environment and the bracket, and requires the ground to be flat and firm, but this method is very beneficial for the maintenance of the later period and the maintenance of the fault. The floor cabinet has a large footprint and is suitable for projects with a large number of screens. The rear space is relatively large, so that the heat dissipation effect is good, and there is still space at the bottom of the cabinet, and other auxiliary equipment can be placed.
