Kookmin University researchers have developed integrated assembly technology for micro-LED displays, the school said Wednesday in Seoul. The method combines mass assembly, chip orientation control, defective-pixel repair and mass transfer on a single alignment platform. The team said the technology could support commercial production of next-generation displays. The study was published in Advanced Functional Materials and selected for an upcoming Front Cover.

A Kookmin University research team has developed an integrated assembly technology critical to the commercial production of micro-light emitting diode (micro-LED) displays.
The university said Wednesday that the technology enables micro-LEDs, key components of next-generation displays, to be precisely assembled at desired positions and in desired orientations.
Led by chemistry professor Do Young-rak, the team has developed a method that integrates several manufacturing processes considered critical to the commercialization of micro-LEDs — including mass assembly, chip orientation control, defective-pixel repair and mass transfer — on a single alignment platform.
