Compared with other display technologies, LED display has the advantages of self-illumination, excellent color reproduction, high refresh rate, power saving, and easy maintenance. The two characteristics of high brightness and super large size through splicing are the decisive factors for the rapid growth of LED displays in the past two decades. In the field of large-screen outdoor display, so far no other technology can compete with LED display technology.
However, in the past, LED displays also had their shortcomings, such as the large spacing between the packaged lamp beads, resulting in low resolution, which is not suitable for indoor and close-up viewing. In order to improve the resolution, it is necessary to reduce the spacing between the led panel screen indoor beads, but the size of the LED beads is reduced. Although the resolution of the entire screen can be improved, the cost will also rise rapidly. The high cost affects the large-scale commercial application of small-pitch LED displays. .
