With the advancement of society and the development of science and technology, in order to obtain eyeball's attention and various impact human visual pictures can be seen everywhere. Advertising screens everywhere on the streets and alleys are constantly playing colorful promotional videos; when entering the command and dispatch center of public security and fire units, you will also see the monitoring video or high -definition of the units on the giant screen. Maps, although the dissemination of visual information is the most intuitive and effective, but the market share of the LCD splicing large screen display as the carrier of this information is also presented in a state of surge. The goals pursued. In the stitching screen scheme, although you see a large screen composed of multiple LCD stitching units, but the splicing processor hidden behind the screen body is actually determined by the large screen display effect.

First, first understand the development history of stitching processors

Although the current splicing processor has changed a lot in technical, it has been just decades from the 1990s to the present. At that time, the Internet had just emerged and was in the sprouting stage of informatization together. Even the special monitor had not been developed. At that time, people at the time replaced the monitoring equipment through CTR technology. And it can only be combined with a single device and cannot be used for multiple equipment. However, with the acceleration of the informatization process and the small -sized single -screen display that can no longer meet the needs of the information display, it is boldly tried to assemble multiple display equipment together. The device is also limited to displaying one signal and multiple devices that cannot be coordinated, not to mention the display functions such as cross -screen, superposition, and segmentation commonly common in today. Based on the needs of users in this area, the first -generation splicing processor came into being, and the real splicing large screen display era has been opened.


Although in the short decades from the listing of the first generation of splicing processors to the present, three major changes have been experienced before and after: PC -type, centralized and distributed. The current connection processor is already a very professional image processing device. It can divide a complete image signal into N blocks and allocate it to N video display units to complete a large display screen with multiple stitching units. At present, there are many types of splicter on the market, but stitching processors such as 2X2, 2X3, 3X3, 4X4 that are often used in LCD stitching screen projects: and with the maturity of technology, the user is in the same maturity, the user is in the technology is in The actual use process can only be customized for manufacturers.


Second, the advantages of the splicing processor

The splicing processor says that simple points can be divided into multiple parts of the way into multiple parts, and the stitching is displayed on a large stitching screen, and no matter the number of signals, and the type of signal, it can roam on any position of the entire LCD stitching wall. , Superimposed. If you want to make the large screen display shocking visual effects, the following two points need to be achieved: First, the distance between the splicing unit and the splicing unit is not easy, and the content of the display is not delayed. Signal source, implementing GIS/PGIS dot pairs on the wall.


Third, the last is the application of the splicing processor

As far as the security monitoring market is concerned, the LCD splicing screen has become the first choice for most users, and in the monitoring and command center of some law enforcement agencies and the monitoring room of enterprises and institutions, most of them use LCD stitching walls as the main display equipment. In order to meet the work needs of the command center, and the splicing processor has become an indispensable equipment. This is mainly because the splicing processor has flexible splicing roaming display, supports any input signal throughout the wall cross -screen roaming, arbitrarily opening window superposition, and zooming, which greatly meets the needs of monitoring display for massive information processing. The unique input -end VGA signal automatic adjustment technology automatically align the RGB video and HV scanning signal and ensure the integrity of the image display. In addition, there is a power heating backup function allowing the equipment to work uninterrupted for 7*24 hours, and meets the strict requirements of monitoring large -screen performance by the dispatch center. In addition to the security monitoring market, the stitching processor outside the security monitoring market is still widely used in the comprehensive places that require large -screen display in advertising media, government agencies, large shopping malls, and education and training centers.


The birth of new tools is often to solve the problems that other devices cannot solve, but with the application of tools and expansion, it is unprecedented innovation. Take the Shangxian device: From CRT to PDP, DLP to LED and LCD LCD splicing screens, with the increase of the scale of the LCD stitching wall display system, and the splicing processor is constantly updating. However, there are no perfect equipment in the world, and today's third -generation splicing processors have solved the problems left over from the previous two generations. They also have problems such as harsh network environment and poor real -time requirements. However, technology will continue to develop forward in the process of solving problems. With the construction of more and more LCD stitching large screen display systems, people's demand for stitching processors will also increase. The manufacturer puts resources into the research and development and improvement of the splicing processor. Only in this way can we promote the development of splicing processors under the condition of a virtuous circle.
