Organic light-emitting diodes (OLEDs) are considered promising devices for next-generation displays and lighting. However, the inhomogeneous surface morphology or residues of transparent tin-doped indium oxide (ITO) on the substrate usually induce defects in the subsequently deposited organic layers, leading to the formation of shunt paths between the anode and cathode, thus deteriorating device performance and stability. Pengfei Wang and Ying Wang of the CAS Institute of Physical and Chemical Technology have achieved highly efficient and stable red, green and blue OLEDs with thickness over 1 μm and low operating voltage which pave the way for high yields in large-area display and lighting devices based on OLEDs.
