Solution-processed OLEDs for printing displays

Abstract

Low-cost and large-scale fabrication technologies are highly desirable for fabricating organic light-emitting diodes (OLEDs) for applications in full-color displays and solid-state lighting. Particularly, printed OLEDs have attracted extensive attention and have great application potential in the fields of commerce, medicine, education and so on. Compared with the vacuum evaporation technique, the printing method has a high material utilization rate and does not need harsh preparation conditions. This review will introduce the development background and advantages of solution-processed OLEDs for printing displays, summarize research progress of light-emitting materials and basic theories of solution-processed OLEDs, and expound on the characteristics of the printing preparation process and the related challenges. Finally, a brief perspective on the future development trend and infinite potential of printed OLEDs will be presented for the commercialization of printing displays.
