Abstract

Coffee ring Inkjet printing OLED Computer Vision and Pattern Recognition Human-Computer Interaction Electrical and Electronic Engineering Electronic Optical and Magnetic Materials Radiology Nuclear Medicine and Imaging
Dry-film uniformity issue from wet-processed OLED because of the coffee-ring effect was improved by compensating the first inkjet-printed PEDOT: PSS with a second inkjet-printed one. Compensation volume, drop anangement, and printing sequence were studied for optimized and improved film uniformity in this work.
