DLP splicing and LCD splicing are the two display technologies in the market of large indoor monitoring screen. Although they have their own advantages, they all share a common problem, that is, the splicing between display units. The high-density LED display has the inherent advantage of seamless splicing. The pixels of high-density display screen are smaller and smaller, the resolution is higher and higher, and the display screen is clearer and more delicate. When displaying standard high-definition image, it can completely meet the requirements of resolution. If the price of high-density lamp is lower and lower, the high-definition and small spacing LED display will occupy a larger market in the field of indoor video monitoring.
High density and small spacing LED display has the characteristics of high-definition display, high refresh frequency, seamless splicing, good heat dissipation system, convenient and flexible assembly and disassembly. As the pixel spacing becomes smaller and smaller, higher and higher requirements are put forward for the mounting, assembly, splicing process and structure of LED.
When the fine pitch led display factory produces the display screen, the fine offset of RGB device position of the high density display screen will lead to uneven display of the screen body, which will inevitably require the mounting equipment of the fine pitch led displays factory to have higher precision.
