Augmentation of OLEDs by Interpolating Electrode in the Hole Injection Layer

Abstract

In this technological era, Organic Light Emitting Diodes (OLEDs) have been attracting considerable attention day by day in the field of display devices. OLEDs have become the most prominent display technology because of its light weight, low fabrication cost, small thickness, wide viewing angle, flexibility, and long life span than other available conventional display devices (CRT, LCD etc.). Numerous techniques have been reported in recent literatures in order to enhance the performance of OLED based displays. In this paper, an interpolating electrode technique has been examined in the hole injection layer (m_MTDATA) of the proposed device. This interpolation accelerates the recombination rate of electrons and holes present in the active layer. Further, this will lead to considerable increment in the current density and luminescent power of the device by 28.86% and 26.91%, respectively in compared to the conventional OLED structure. Thus, making the proposed device suitable for low driving voltage display applications.
