High Resolution Electrohydrodynamic Printing For Micro-LED Display (Printed Electronics USA 2020)

Dr Doyoung Byun, CEO
ENJET Inc.
Korea
 

Presentation Summary

This talk includes introduction to a high resolution (1μm) printing method for printed electronics, whose jetting mechanism is based on the electrohydrodynamics. The electrohydrodynamic (EHD) jet printing has been received much attention as an effective manufacturing method for high resolution patterning in sub-microscale. The EHD high resolution printing with bonding material has been actively applied in micro-LED display fabrication. eNanojet printer (www.enjet.co.kr) provides a unique printing solution and automatic printing function that ensure the precise quality for chip bonding and 3D electrode fabrication. The silver-based bonding materials developed by ENJET are also optimized for attaching micro LED chips. Our solution could realize 100 % lighting efficiency on micro LED display fabrication.
