Abstract

In this paper, we describe a novel color patterning method for the fabrication of large area full-color AMOLEDs. Laser Induced Thermal Imaging (LITI) is a laser addressed thermal patterning technology with unique advantages such as excellent uniformity of transfer film thickness, capability of multilayer stack transfer, high resolution and scalability to large-size mother glass. We developed and optimized transfer films, structure of OLED layers, and laser scanning conditions for the patterning of evaporated small molecules. As a result, we achieved excellent LITI device stability which yielded the device life time more than 25,000 hrs at 250 cd/m2 white brightness.
