N2 - Low driving voltage, high luminance, and high efficiency are the important parameters of organic light-emitting diodes (OLEDs) for their application of display and lighting. Usually, synthesis of new materials, doping technique and designing suitable device structures were the main methods to use for realizing the aim of the wide application of OLEDs. In this paper, we try to obtain a high efficiency and low driving voltage tandem OLED with ultrathin films through optimizing the thickness of hole transporting layer (HTL), electron transport layer (ETL), emission layer (EML), and charge generation layer (CGL). As a result, we got the ultrathin tandem OLED with a very low driving voltage of 7.44 V, the luminance of 16,080 cd/m2, the current efficiency of 16.08 cd/A, and power efficiency of 6.28 lm/W, respectively. This research not only saves the cost and improves the power efficiency, which may supply a theoretical basis for the development of OLEDs in the lighting field.
