Abstract: ?In this work, we proposed that ITO-free semitransparent Ni/Ag/Ni tri-metal conductor could be applied in flexible blue phosphorescent OLEDs, which have sensitive light response of blue range with high energy. Although the highest electrical and optical characteristics values, such as luminance efficiency and external quantum efficiency, using ITO electrode were better than that of devices using tri-metal conductor, roll-off efficiency and device stability were suitable for blue phosphorescnet OLEDs. This work, consequently, could be proposed on additional flexible OLEDs and light applications for ITO-free process.
