In the past two years, the implementation of policies such as safe city and intelligent transportation construction, which are closely related to the development of security, and the enhancement of public awareness of security make the application of large screen display industry in the field of security maintain a good growth momentum. From the perspective of application market, Safe City is the current and future large screen display industry growth field, especially the second and third-tier cities begin to highlight the huge market potential. However, the project of Safe City is a very large and complex system, and involves a large area, a complex environment, a large number of images, which requires multi-level control, and requires high image clarity, good real-time performance and other high requirements, so that the traditional system simply for the purpose of display is far from meeting its use needs. This requires a large screen Mosaic display system, through the large screen to achieve comprehensive management.
In the current market, the displays in the field of security are mainly divided into two categories: one is the liquid crystal display using traditional CCFL(cold cathode fluorescent lamp tube), that is, LCD, and the other is the LCD using LED(light emitting diode) backlight. LED display can also be called monitor or splicing screen in the security industry. With the improvement of LED technology in recent years, various models of monitor emerge in endless stream, lighter and lighter, clearer and clearer, more and more bright color. Due to the market demand for some oversized splicing screen projects, which can meet the requirements of large number of signal sources and complex control system, and LED display has broken through the limitation of patchwork, LED display has a very promising application prospect in the security industry. At present, it is mainly used in the field of video conference and video surveillance. Such as transportation, energy, public security, emergency rescue and so on.

Hd intelligence will be the development direction of LED screen in the field of security, the Third Plenary Session of the "Decision" in the 13th deepening of science and technology system reform said to strengthen the application and protection of intellectual property rights, improve the incentive mechanism of technology innovation. The LED industry generally believes that this will be conducive to intellectual property protection in the field of LED, conducive to promoting the development and innovation of new technologies and new products in the LED industry. On the LED monitoring display technology breakthrough direction, President Yang pointed out that the future monitoring display equipment must be in the direction of high-definition technology development.

From cathode ray tube display technology, liquid crystal display technology, plasma display technology to the evolution of organic light emitting diode display technology, the latter than the former in thickness, weight, brightness, resolution, function, view Angle, response time, operating temperature range are much superior. Picture tube also from the sphere, plane right Angle, cylinder to flat picture tube evolution, image realistic without deformation. For example, plasma monitor is a new generation of products after CRT/LCD, which is characterized by thin thickness, excellent resolution, can make a large monitor, there is no curved visual surface, the color display more bright, more bright, application prospects are very broad. But liquid crystal is currently recognized as the most suitable for use in the security field as a professional monitoring terminal products. For example, the service life problem, under normal circumstances, the service life of the LCD screen can reach more than 50,000 hours, the resolution can easily do above the standard HD or even reach the full HD grade of 1080P, the power and heat is relatively small. But comparatively speaking, LED display is more competitive than LCD.

Last year saw the explosion of small-pitch LED displays. In the field of security, the biggest advantage of small-pitch LED displays is that they are completely seamless and display colors that are natural and realistic. At the same time, in the later maintenance, LED display has a mature point by point correction technology, more than one or two years of use of the display can use the instrument for one-time correction of the whole screen, the operation process is simple, the effect is also very good. At present, LED small spacing is actually used in monitoring and security, command and dispatch, intelligent transportation and other fields. In the future, if the LED small spacing display can have a greater breakthrough in high-definition and intelligence, the product competitive advantage will be further reflected.

From the above content, LED display in the field of security shows a greater advantage and development potential. In the future, LED display will occupy a place in the field of security, LED display will promote the progress of security field, security field will also promote the development of LED display.
