Researchers from Science Tokyo developed the world's lowest operating voltage white OLED device

Researchers from the Institute of Science Tokyo (Science Tokyo) led by Associate Professor Seiichiro Izawa have developed a white OLED device that operates at the lowest voltage ever, at under 1.5 V. The research is built upon previous endeavors in creating low-voltage blue OLEDs using an upconversion process based on triplet–triplet annihilation (TTA). The OLED device emits blue light through the TTA. The researchers doped the device with a sky…
