Abstract
Stacked organic light-emitting diode (OLED) devices with two terminals have been fabricated by successive application of solution coating and vacuum deposition. We seamlessly engineered the two processing steps by optimizing the semi-transparent metal electrode and the carrier transport buffer layer, and investigated the electrical and optical properties of the thus-prepared devices. The top and bottom OLEDs can be independently addressed by switching the polarity of the voltage applied to the two terminals. The emission color from the stacked OLED devices is easily tuned between green and blue or red and blue, by adjusting the offset of the alternating current applied to the stacked OLED devices. Thus, a simple approach is presented towards printable and color-tunable organic lighting for the future. © 2016 Optical Society of America.
