Abstract

The preparation of organic electroluminescent diodes (OLEDs) by printing with the potential advantages of high material utilization, low equipment cost, simple process flow, and favorable for large-area device preparation, is expected to be the next generation of OLED fabrication method. In this paper, PEDOT: PSS and CDBP: Ir(bt)2acac functional layers were prepared by spin coating/printing and characterized, respectively. The results show that the double layer printing device achieved the best performance, the maximum brightness and external quantum efficiency reach 4357cd/m2 and 2.45%, even better than that of the spin coated reference. It indicates that the ink-jet printing process has a potential to overwhelm the spin-coating one for constructing high performance OLED.
