Researchers at Kookmin University have created an integrated micro-LED assembly technology, crucial for commercial production of micro-light emitting diode (micro-LED) displays. This technology allows for precise assembly of micro-LEDs at specific positions and orientations. The method, led by chemistry professor Do Young-rak, combines several manufacturing processes necessary for micro-LED commercialization, such as mass assembly, chip orientation control, defective-pixel repair, and mass transfer, onto a single alignment platform.
The research, published in the international journal Advanced Functional Materials under the title "Dielectrophoretic Assembly, Repair, and Transfer Technology for Micro-LED Display Boosted by Injection-Suction Printing," was also chosen for the Front Cover of an upcoming print issue. Eo Yoon-jae of the university's chemistry department was the first author, with Do Young-rak serving as the corresponding author.
