| Summary: | 碩士 === 國立高雄應用科技大學 === 電子工程系碩士班 === 102 === We demonstrate the electroluminescence (EL) properties of a low power consumption, high efficiency and stability of tandem organic light emitting diode (OLED). Its EL properties were improved by using a charge generation unit (CGU) combining a doped hole transporting layer (HTL) with bipolar transport ability. In addition, the design of a mechanism to align the energy level between the HTL and CGU shows effectively decreasing the operating voltage of the devices.The deposition of a LiF/Al/NPB:HAT-CN CGU in tandem OLED achieves in more than twofold improvement in the current efficiency. Our findings show that bipolar transport ability is a promising approach for easy-fabrication as well as high color rendering index and chromatic-stable tandem white OLED for future display and lighting application.
