Over 1500 PPI quantum dot color conversion array by lift-off
This study explores the application of lift-off process for the patterning of quantum dot (QD) pixels using CdSe/ZnS core-shell colloidal QDs. The evaluation of the influence of different solvent and binder systems on the effectiveness of the pixelation is detaily discussed. By optimizing the solvent and binder combination, the fabrication of multi-color QD patterns with pixel sizes ranging from 5 to 200 μm were demonstrated, achieving blue light conversion efficiencies exceeding 18% and 25% for red and green pixels. It is also improved pixel uniformity, stability, and resolution, lying the foundation for the development of ultra-high-resolution, QD Micro-LED display. However, challenges remain in maximizing the utilization of blue light and packaging of QD layers. Future research will aim to develop high-quality QD inks suitable for photoresist lift-off and optimize the QD Micro-LED system to further enhance the performance and stability of QD-based displays.
期刊介绍：
The Journal of the Society for Information Display publishes original works dealing with the theory and practice of information display. Coverage includes materials, devices and systems; the underlying chemistry, physics, physiology and psychology; measurement techniques, manufacturing technologies; and all aspects of the interaction between equipment and its users. Review articles are also published in all of these areas. Occasional special issues or sections consist of collections of papers on specific topical areas or collections of full length papers based in part on oral or poster presentations given at SID sponsored conferences.
