The National Intellectual Property Administration has announced that XuXian Future (Beijing) Technology Co., Ltd. has been granted a patent titled “A Device for Mass Transfer of Micro LED Chips,” with the authorization number CN221885132U and an application date of February 2024. This innovative patent utilizes a recessed area at the pad location combined with magnetic attraction principles to achieve rapid positioning and installation of Micro LED chips, ensuring high reliability.

Patent Summary
The patent details a device specifically designed for the mass transfer of Micro LED chips within the display technology sector. The mass transfer device comprises Micro LED chips, a transfer substrate, and a shaking unit. The transfer substrate features designated pad locations with recessed areas. One of the electrodes at the pad location possesses magnetic properties, while both electrodes of the Micro LED chips are also magnetic. The magnetic properties of the electrodes on the Micro LED chips oppose those at the pad location. The shaking unit is connected to the transfer substrate and facilitates the movement necessary for the Micro LED chips to settle into the recessed areas.
Company Overview
XuXian Future specializes in the research and development of Mini/Micro LED display production technologies, software development, technical services, and system integration. The company operates five major production bases across Shandong, Hunan, Jiangxi, Anhui, and Zhejiang.

The factory in Hunan successfully lit its first batch of inverted COB Mini LED display cases in July this year. This facility is projected to produce 66,000 square meters of Mini LED display modules annually. With the Hunan factory ramping up production and ongoing developments in the Anhui and Zhejiang factories, XuXian Future anticipates achieving an annual production capacity of 350,000 square meters of LED modules by 2025.

Innovations in Micro LED Technology
In April this year, XuXian Future showcased the world’s first true Micro LED thin-film chip, known as the MiP Direct View 4K Large Screen, which features the removal of the native substrate. This product incorporates advanced technologies such as chip miniaturization, substrate removal, wafer-level mass transfer, and semiconductor fan-out packaging.
To further advance Mini/Micro LED technology development, the Southern Display Technology Research Institute of XuXian Future was officially established in Shenzhen in August this year. This institute focuses on foundational research in the new display field, building a multidisciplinary structure encompassing materials, processes, optics, and electronics. It aims to establish a comprehensive technical and talent reserve, boasting a complete R&D team from technological development and process manufacturing to production components and small-pitch modules, along with a full LED industry layout.
