- P‐76: Optimization of Inkjet Jetting for Ultra‐Fine Droplets Eunbyuel Lee Wooree Ko Euna Ko Jeongho Yi Myung soo Huh SID Symposium Digest of Technical Papers Inkjet printing technology is used in many fields including display industry, due to its advantages such as high productivity, high quality, flexibility in patterning and scalability from a small to a large substrate. In particular, the conventional evaporation method for producing pixel displays has been becoming replaced by inkjet printing due to its less consumption of expensive materials and inclusion of particles for better efficiency and quality of display. As display resolution increases, it is essential to have a printhead with ultra‐fine droplets, and to operate it in highly reproducible and stable conditions with optimal jetting quality plays a critical role in succeeding mass production. In this study, we investigated the jetting conditions such as jetting viscosity, circulation rate, meniscus pressure, printing speed, and incoming ink temperature, and their effects on jetting quality as well as facility for maintaining the printhead. We expect that such an optimizing process for jetting ultra‐fine drops will contribute to the reliable printing process for high resolution displays. 10.1002/sdtp.18539 http://onlinelibrary.wiley.com/termsAndConditions#vor
