Abstract

AbstractWe present the light‐on results of our 65‐inch organic ***light‐emitting diode (OLED) panel fabricated by the inkjet printing (IJP) process. The panel uses solution‐processable OLED material for the hole injection layer (HIL), the hole transporting layer (HTL) and the emitting layers (EML) for the red, green and blue colors. It is found that fine‐tuning the vacuum dry speed after the inkjet printing process can improve the uniformity of the pixels. The results show that we can successfully fabricate a 65‐inch OLED panel with a high degree of pixel uniformity.
