Capillary Flow Control in Vacuum Drying for Uniform Pixel Thin Films in Inkjet-Printed OLEDs: Effects of Pumping Speed and Binary Solvent Ratios
Eliminating the coffee-ring effect caused by capillary flow is crucial for achieving uniform thin films in inkjet-printed display pixels. This study investigates methods to suppress capillary flow influence during the vacuum drying process to form uniform inkjet-printed OLED thin films. A drying mod...
