P‐12.1: Inkjet Printed Quantum Dots for Full Color Active Matrix Micro‐LED Display

Inkjet Printed Quantum dots (QDs) display has attracted much attention due to their excellent optical properties and solution process. Especially, QDs can act as effective color conversion for light emitting diodes (LED). In this work, we fabricated 4‐inch QD‐microLED display panel by inkjet printing technology, using a simple quantum dots ink with cross‐linkable organic small molecule additive for binding QDs with film together. Finally, an active matrix full‐color QDs‐MicroLED display prototype was demonstrated with a high color gamut of 122% NTSC (94%BT.2020).
