Abstract: In this study, we report the thermally activated delayed fluorescence (TADF) organic light‐emitting diodes (OLEDs) having enhanced efficiency. We optimized TADF OLED by HTL, ETL materials and thickness. An enhanced power efficiency, current efficiency and external quantum efficiency were achieved in optimized TADF OLED.

Abstract: In this study, an organic light‐emitting diode with improved light extraction was fabricated by embedding nanoscale vacuum line layer (nVLL). The nVLL increases the optical efficiency both by the perspective of inserting extremely low refractive index materials between the substrate and the anode, and also by the photonic crystal effect from a nano‐periodic structure.

Abstract: We demonstrated light extraction in flexible OLEDs(FOLEDs) by using nano‐sized random pattern(nRP). Simply fabricated nRP on flexible substrate reduced optical loss through scattering effect. Compared to conventional device, FOLEDs with nRP showed improved power(+36.36%), current(+25.64%) efficiency at luminance of 4000cd/cm2, and improved external quantum efficiency(+22.26%) at current density of 100mA/cm2.

Abstract: A hybrid buffer layer with superior plasma protection ability and high injection efficiency was developed. The hybrid buffer layer composed by dual‐layered structure of HATCN/MoO3 enhances hole‐injection efficiency and protects organic layers under the top electrode. This hybrid buffer layers improve the electric characteristics of inverted top‐emitting organic light‐emitting diodes.

Abstract: We fabricated the organic light‐emitting diodes (OLEDs) having enhanced optical efficiency with nano‐sized stripe auxiliary electrode. It could supplement the shortcomings of micro‐sized that while maintaining the high optical advantages. We can simply deal with the parameters of nano‐sized auxiliary electrode by conjugating the conditions of laser interference lithography (LIL). The demonstrated process can be also easily acceptable to mass production of the large area OLEDs applications.

Abstract: In this study, we demonstrate high‐efficiency distortion‐free spectrum Organic Light‐Emitting Diodes (OLEDs) using photonic crystal (PC) and micro lens array (MLA). The PC structure is fabricated by laser interference lithography (LIL), which enables simple and cost‐intensive manufacturing for mask less and largely scalable process. Finally, we obtain a significant results that external quantum efficiency (EQE) and the power efficiency (PE) were enhanced by up to 150% and 250%, as compared reference.
