40.1L: Late-News Paper: A Novel RGB Color Patterning Method for Organic Light‐Emitting‐Diodes: Joule‐heating Induced Color Patterning (JICP)

A novel RGB color patterning method for the fabrication of AMOLEDs was demonstrated on a lab scale in this work. Jouleheating Induced Color Patterning (JICP) is a high resolution patterning process where sublimation of small organic molecules is induced by applying electric pulse to a pre-patterned conductive layer on a donor glass. It was found that the JICP process has a potential for high resolution patterning of >700 ppi and for patterning large-sized panels such as Gen. 8 glass substrate.
