Since the opening of the market of lianchengfa small spacing LED display screen, it has rapidly penetrated into many control fields such as residential area, commercial area property, traffic guidance and so on. The development of the current social market has been flying by, which also implies that the rapid development of the current intelligent era has far-reaching impact on our lives. So why are small-pitch LED displays so widely used?

　　With the further reduction of point spacing, small spacing LED display with no visual seam, good color brightness consistency and other advantages, gradually began to replace the high-end control room market, conference room market and security monitoring display market monopolized by DLP(projection) display screen, LCD(liquid crystal) display screen and project projection fusion display screen. The indoor hd small-pitch series is one of the main series of Lianchengfa at present. It has the characteristics of clear and even picture quality, and the module has correction data storage, which can be directly imported into the correction data, so it has received great attention from the market. Among them, P1.5625 and P1.667 small-spacing display screens have been set foot in professional fields such as traffic monitoring, security industry, electric power industry and radio and television industry, and the market response is very good.

　　These control areas need to display rich and complex signals, digital signals more than video signals, put forward nearly strict requirements for products and technologies, such as high-resolution fine display, high gray reduction display under low brightness, high refresh rate, high consistency and uniformity, low noise, low heat dissipation, etc. Even the comfort of sustained viewing for a long time is very high. These, only small spacing display can meet the requirements, infiltration of nature is taken for granted.

　　For example, in the traffic field, we usually face a variety of complex environments. The LED display with high resolution, high refresh and more stable performance can freeze the faces of people, action moments and license plates faster and clearer. These, whether used to reproduce the scene or to analyze the crime scene, traffic accident responsibility can play a certain auxiliary or even decisive role. This point is enough to see the importance of small spacing products in the control room application field.

　　Insiders speculate that in the next 5 years, indoor small spacing LED display will become the mainstream display technology in the domestic control room market, and LCD(liquid crystal) display, laser projection and DLP display will share nearly 10 billion yuan of market share.
