The development history of LED small pitch screens can be traced back to 2010, which marked the birth of small pitch LED display technology. Prior to this, LED full-color screens were mainly used for large outdoor billboards, suitable for long-distance viewing, with relatively wide pixel spacing. However, with the continuous advancement of technology, small pitch LED displays have emerged, successfully achieving the transition from outdoor to indoor applications.

The initial small pitch LED display screens were produced using surface mount SMD packaging technology, with a dot pitch of 2.8mm. This innovation has opened up new markets for LED display technology, especially in high-end professional display fields such as conferences and command, where small pitch LED displays have quickly gained widespread application. Its emergence has caused a huge shock in the high-end professional display market, laying a solid foundation for the further development of LED display technology.

With the continuous breakthroughs in technology, the pixel spacing of LED displays is gradually decreasing. After 2016, small pitch LED displays have gained widespread recognition in the market, with a rapid increase in market penetration rate. In 2018, mini LEDs with a dot spacing of less than 1mm were mass-produced and began to be used in high-end laptops and high-end displays in esports. At the same time, advanced merchants have also begun to introduce Micro LED technology, whose chip size is getting smaller and gradually being applied in fields such as mobile phone screens, smartwatches, VR/AR devices, etc.

In terms of application scenarios, small pitch LED displays initially successfully opened up the professional indoor LED display market, such as command centers, monitoring centers, enterprise conference rooms, etc. Subsequently, it further expanded to the fields of commercial display conferences and education, becoming the main display device for various large indoor display scenes. In addition, with the continuous maturity of technology and the reduction of costs, small pitch LED displays have been applied in more fields, such as cinemas, stage performances, sports venues, etc.

In recent years, with the continuous development of Mini/Micro LED display technology, related industries have also experienced rapid growth. The establishment of the Mini/Micro LED Display Industry Branch of the China Electronic Video Industry Association and the convening of related forums have provided a platform for learning and communication in the industry, promoting the high-quality development of the new display industry. At the same time, some companies such as Zhouming Technology have made significant achievements in the field of LED displays, and their UC-A41 LED cinema screens have successfully obtained Hollywood DCI certification, marking an important breakthrough in the domestic LED display industry's entry into the cinema market.

In short, the development process of LED small pitch screens is a continuous process of innovation and breakthrough. With the continuous advancement of technology and the expansion of application scenarios, small pitch LED displays will continue to play an important role in the future, providing efficient and high-quality solutions for various display needs.
