A newly developed white organic light-emitting diode operates at under 1.5 volts, report researchers from Institute of Japan. By using triplet–triplet annihilation to generate blue light at low voltage and adding in yellow and sky-blue dopants, the research team achieved efficient white emission. This breakthrough could contribute to reducing energy consumption in the future in state-of-the-art displays, including television backlights and lighting devices, advancing portable electronics and sustainable technologies.
