We present a ligand-exchange-free photo-patternable quantum-dot photoresist (QDPR) with high photolithographic uniformity. The dispersion mechanism between the QD’s surface ligands and the functional groups of photoresist polymers are studied. Results show that the dispersibility and photoluminescent intensity of this QDPR can be both improved by controlling dispersant and antioxidant. For device demonstration, multi-colored quantum dot color conversion films (QDCCF) were prepared and patterned by a photolithography process. High QD dispersibility and film-forming uniformity were both achieved with this QDCCF. It is believed that the proposed QDPR has the potential to be extensively used in lighting or display applications.

Quantum dot (QD)-based RGB micro-LED technology is seen as one of the most promising approaches towards full color micro-LED displays. In this work, we present a novel nanoporous GaN (NP-GaN) structure that can scatter light and host QDs, as well as a new type of micro-LED array based on an NP-GaN embedded with QDs. Compared to typical QD films, this structure can significantly enhance the light absorption and stability of QDs. As a result, the green and red QDs exhibited light conversion efficiencies of 90.3% and 96.1% respectively, leading to improvements to the luminous uniformity of the green and red subpixels by 90.7% and 91.2% respectively. This study provides a viable pathway to develop high-uniform and high-efficient color conversion micro-LED displays.
