For modern warfare and military exercises, information visualization occupies a very important position. In the battle, the competition and confrontation of the "right to make information" largely determines the outcome of the warring parties. In the face of military operations and sudden major incidents and natural disasters, the military, armed police, public security and disaster relief departments need to exchange information and emergency command in a timely and rapid manner. It is necessary to understand the situation of the rescue site in a timely manner, and then timely and scientifically Make strategic decisions, coordinate the mobilization of human and material resources, and launch rescues as quickly as possible to minimize losses. In the process of combat command and the discovery and rescue of major natural disasters, the timely transmission of information is very important. The requirements for the information system are to be able to accurately and comprehensively display various types of emergency information, image data, strategic position maps and on-site conditions in a timely, comprehensive and rapid manner, to improve the ability of emergency response and the efficiency of work. 
With the development of the army's informatization construction, the "right to make information" has become a new growth point for the combat effectiveness of the military. Effective command and control has become the key to the success of the army. To this end, the commanding organs at all levels have followed the trend and continued to intensify their efforts in the construction of information technology, which has greatly promoted the development of military command information. The innovation of LED high-definition seamless splicing large-screen display technology has also injected fresh blood into the army's information construction.
In recent years, the small-pitch LED display technology has advanced by leaps and bounds. It not only inherits the advantages of LED display without seams, wide color gamut, high brightness, etc., but also effectively overcomes the technical problems of low brightness, high gray and high refresh rate, and thus can restore ultra-high gray. The delicate picture ensures the accurate display of digital signals, graphic information and text information, and meets the high standard requirements for color, brightness and clarity of the combat command and video conference display.
The small-pitch LED high-definition seamless splicing large screen can help the military to build a combat command system and a remote video conferencing system. Through this system, not only can intuitive, real-time, all-round and rapid display of all kinds of information, image data, strategic position maps and on-site conditions, flexibly realize military exercises, operational command, assist decision-making, organize army training, Video conferencing, real-time monitoring and other complex functions, and greatly promoted the military information visualization and intelligent construction, and improved the work efficiency and combat capability of the modern army.
In the daily training and operational command of the troops, the massive information can be graphically represented in real time through the small-pitch LED display system, which provides strong support for decision-making and provides efficient and rapid communication and feedback for the command. In recent years, small-pitch LED display technology has gradually matured and improved, and is increasingly used in army building. At present, small-pitch LED displays have begun to show off in the military field, and military applications created by small-pitch LED display companies are not uncommon.

Real-time recording and broadcasting is a more important function in the display system. The typical application in the military system is the recording and broadcasting of military combat exercises, military meetings, teaching, etc.; this can be broadcast live to the leaders or work in different places. Personnel can also choose to play afterwards, which is convenient for discussion and re-learning. It is conducive to analyzing and summarizing lessons learned afterwards, so as to improve the combat capability of the modern army. The exercise command can be fully understood through the LED high-definition screen in the combat command center. Fight against both sides. This function supports simultaneous combined recording of multiple signals, such as audio and video information against the two sides during the exercise, online sand table deduction dynamics, radar screen information and other content recording.
to sum up:
In the military field, command and control applications often need to present the output signals of multiple subsystems in the back-end system comprehensively, accurately, and regularly on the front-end large screen, and use images and data to complete management and decision-making. This application field requires large-screen display to achieve high display accuracy and stability, and is often used in 7x24-hour all-weather applications, requiring high reliability and stability. The small-pitch LED display, with its ultra-thin cabinet, seamless splicing, high stability, realistic image quality and other technical advantages, is triumphant in the high-definition display field, and is also expected for military construction.
The small-pitch LEDs are seamlessly spliced ​​together to ensure the integrity of the picture and the lossless display of details; using high-precision point-by-point correction technology, using advanced green reproduction and skin color reduction functions, it fully adapts to the human eye's feeling habits; High refresh rate and high gray level, the picture is delicate and realistic, HD camera can also capture every wonderful picture very well; At the same time, in the case of ensuring the gray level of the LED display, the brightness of the display terminal is appropriately reduced, and the brightness is collected in the environment. Under the control of the interactive system for displaying the brightness control of the terminal, the brightness of the display terminal and the change of the ambient brightness can be intelligently adaptive, and the problem of insufficient brightness of the traditional spliced ​​large screen (DLP and LCD) is solved.
In addition, the small-pitch LED display system features ultra-large viewing angle, fanless cooling, ultra-quiet, power signal redundancy backup, ultra-high stability and reliability, which fully meets the high standards of the military field.
At present, all countries in the world are paying more and more attention to the informationization of the military. It is not difficult to foresee that arming the entire army with modern science and technology products has become an inevitable trend in the building of our military. With the improvement of small-pitch display technology and the price reduction, future combat command systems and video conferencing systems based on small-pitch LED displays will be increasingly used in the field of militarization to help the army's information construction.
