According to reports, the BOE Huacan Micro LED factory was invested and built by BOE Huacan Optoelectronics (Guangdong) Co., Ltd. The factory officially broke ground at the end of July 2023. After going through important milestones such as topping out, moving in process equipment, and product lighting, the project achieved product delivery in just 20 months.
BOE's Huacan Micro LED factory mainly produces Micro LED wafers and pixel devices, targeting ultra-large and ultra-small high-definition display scenarios, and is used in large-size commercial displays, AR/VR head-mounted display devices and wearable devices. When fully operational, it will have an annual production capacity of 24,000 sets of Micro LED wafers (6-inch wafers) and 45,000 pixels of Micro LED devices.
The successful mass production of BOE Huacan's Micro LED factory is inseparable from the strong support of the Zhuhai Municipal Government and the Jinwan District Government. In his speech, Mr. Ao Wei, Deputy District Mayor of Jinwan District, stated that in the future, the Jinwan District Committee and Government will continue to provide comprehensive support to help BOE Huacan build a new display industry cluster in Zhuhai, contributing to Zhuhai's implementation of its "manufacturing-led" strategy and accelerating its transformation into a "trillion-yuan industrial powerhouse."
Mr. Zhang Zhaohong, Chairman of BOE Huacan, stated that in the future, the company will adhere to a dual-engine strategy of "technology + manufacturing," attracting more high-quality enterprises to settle in Zhuhai and cultivate the Zhuhai market. The Micro LED project delivered this time is an important platform for BOE Huacan's development of new display technologies, containing unlimited possibilities and enormous potential.
Four Advantages of the World's First 6-inch Micro LED Mass Production Line
Micro LED is hailed as the ultimate display technology, boasting high brightness, high contrast, high response speed, low power consumption, high reliability, and long lifespan. Compared to technologies such as LCD, OLED, and Mini LED, it offers significant advantages in image resolution, system battery life, distortion design, environmental compatibility, and overall compatibility.
However, Micro LED technology is still in its early stages of development. To accelerate its mass production, the entire LED industry chain is working to overcome the challenges of mass production. BOE and HC SemiTek, as key players in the LED industry, are leading the development of the Micro LED industry through their advanced production planning.

As the world's first production line to achieve large-scale mass production of 6-inch Micro LEDs and the world's first integrated production line for wafers and packaging modules, BOE's HC SemiTek Micro LED factory has significant technological advantages in MPD packaging, production line automation, mass transfer, and equipment localization, thus realizing Micro LED Pcroix:
MPD (Multi-Pitch Deposition) Micro LED technology involves transferring Micro LED chips onto a substrate for encapsulation, cutting them into small packages, then splitting and mixing the light within these small packages before performing a surface mount process. MPD can significantly reduce the manufacturing cost and increase the yield of micro-pitch LED displays.
BOE's HC SemiTek Micro LED factory uses MPD (Multi-Package Diode) product form to ship products, which solves some of the pain points of COB (Chip-on-Board) packaging, significantly reduces the packaging costs and precision requirements of downstream packaging manufacturers, and effectively improves the synergy of the upstream and downstream industrial chains of the display chip industry.
Continuous optimization of mass transfer efficiency: Rapidly and accurately transferring massive numbers of Micro LED wafers to target locations is a core challenge in Micro LED production. To address this challenge, BOE's Huacan Micro LED factory has successively purchased more than twenty mass transfer and auxiliary equipment. The mass transfer stations employ semi-automatic/fully automated operations, reducing labor costs while improving operational accuracy, thereby enhancing the overall yield of produced products.
Highly Automated Production Line: BOE's Huacan Micro LED factory is reportedly the industry's first Micro LED chip manufacturing plant to achieve full production line automation. Through the full integration of automated systems such as MCS, RTD, and EAP with equipment like automated material handling, electronic shelving, and Lifters, the factory effectively improves productivity and product quality stability, reduces operating costs, and enhances the safety of its workers.
High degree of equipment localization: To efficiently build its Micro LED production line, BOE's Huacan Micro LED factory boasts a domestic equipment localization rate exceeding 80%, significantly reducing costs in both the initial and later stages of the project. Furthermore, through the large-scale application of domestically produced equipment, the factory ensures the confidentiality of key process technologies and information related to Micro LED products, promotes collaborative development across the upstream and downstream of the domestic Micro LED chip industry, and will help propel China's Micro LED industry to a leading position in the global market in the future.
Summary <br /> The product delivery from BOE's Huacan Micro LED factory marks a new stage in the large-scale production of Micro LED technology.
Leveraging its technological advantages in MPD packaging, mass transfer, production line automation, and equipment localization, BOE HC SemiTek has successfully solved the challenges of Micro LED mass production, driving industry chain integration and collaborative development. In the future, BOE HC SemiTek will continue to deepen its expertise in Micro LED technology, injecting new momentum into the global upgrade of display technology. (Text: Irving)
