December 3, 2024 — Sanan Optoelectronics launched its official WeChat account for Aimaipu Optoelectronics, a subsidiary brand, offering an in-depth look at the Aimaipu brand and its current MiP technology production capacity.
According to the official WeChat announcement, Aimaipu is an independent brand under Sanan Optoelectronics’ wholly-owned subsidiary Hubei Aimaipu Optoelectronics Technology Co., Ltd.. The brand is committed to developing high-end components for Micro LED display technology and is backed by a professional R&D team with a global perspective. As of October 2024, Aimaipu holds a total of 360 patents related to Micro LED technology, including 332 invention patents.

Moreover, by October 2024, Aimaipu successfully developed and began mass production of several Micro LED devices, including MiP0404, MiP0202, and MiP0.78, MiP0.9 display panels. The company currently has a MiP (Micro LED in PKG) production capacity of 2,000K units per month, with plans to expand this to 5,000K units per month by the end of 2025.
In addition to these accomplishments, Aimaipu is also working on a new product: AMIP (AM IC & Micro LED in PKG), which will enable a transition from PM-driven to AM-driven LED displays, further improving display quality.
On November 21, 2024, during the MiP Production Progress and Development Strategy keynote speech, Sanan Optoelectronics Vice President Xu Chenke stated that the company plans to reduce costs through economies of scale while enhancing competitiveness through technological innovation to further advance MiP technology.

From an industry perspective, MiP technology plays a key role in facilitating the application and promotion of Micro LED technology in large screens. The development of MiP devices addresses several key challenges in Micro LED mass production for large screens. Without the use of MiP-based discrete devices in Micro LED large screens, the integrated packaging process faces the following major difficulties:
- Micro LED chip mass transfer is difficult to balance in terms of precision and yield.
- The optoelectronic testing of Micro LED chips is challenging, and the cost of sorting tests is high.
- The precision requirements for the main display board circuits that support Micro LED chips are high, with small line widths and spacings, which are difficult to achieve.
- The integration of Micro LED packages leads to contrast and wide-angle consistency challenges.
- If defects appear in the integrated packaging solution, the repair costs are high.
To address these issues, MiP adopts a modular approach, dividing the panel into smaller packaged units. By controlling the yield of smaller areas, it can overcome the challenge of achieving yield consistency in large-area displays.
