Novel Organic Light-Emitting Diode with Ultralow Turn-on Voltage for Blue Emission
Tags: Tokyo Institute of Technology, Japan, Consumer Goods & Services, Electronics & Robotics
Researchers from Tokyo Tech have developed an upconversion organic light-emitting diode (OLED) that achieves blue emission at an ultralow turn-on voltage of 1.47 V, circumventing the traditionally high voltage requirements. This advancement has significant implications for commercial smartphone and large screen displays, which typically rely on higher voltages. The OLED utilizes a novel mechanism involving triplet-triplet annihilation (TTA) to efficiently produce blue light. The device employs specific materials to enhance charge transfer and reduce the voltage needed for operation. This technology paves the way for more energy-efficient displays and could also benefit other organic electronic devices.
