Abstract
Significant progress has been achieved in the area of full-color organic light-emitting diodes (OLEDs) in terms of their high performances for evaporated (RGB side-by-side patterning or multi-stack (tandem) high efficiency white technology for the large area TV). In case of printable material for RGB, it is still a valuable candidate as an alternative of evaporable emitter. However, despite intense efforts, the formation of uniform pattern RGB line in a large scale for commercial application, with sub-50-nm thin film of organic emitter pixels by inkjet printing, remains challenging. It requires an ink that complies with certain specifications and environment in terms of viscosity, surface tension, and vapor pressure. In this chapter, fundamentals of inkjet printing as well as specific technical issues such as ink formulation, jetting processes, development of printable materials, and uniform scale-up are briefly illustrated.
