51‐1: Distinguished Paper: High Precision and High Stability Inkjet Printing Technology for QD Color Converter‐type Micro LEDs Display

Abstract

This paper proposed the inkjet head and the equipment. To realize high resolution printing with QD ink, we had to overcome the problem of robust inkjet head for QD particles. We proposed the inkjet head to eject high viscosity ink and the ink circulation system to avoid aggregation. Also, we proposed the DPN technology for high resolution printing. By combining the inkjet head technology and the equipment technology, we demonstrated QD color converter‐type Micro LEDs display panels.
