Publication number: 20240090326Abstract: The present disclosure relates to an organic compound having the following structure, and an organic light emitting diode (OLED) and an organic light emitting device including the organic compound. The organic compound can be a bipolar compound having a p-type moiety and an n-type moiety and has high energy level and proper energy bandgap for an emissive layer of the OLED. As the organic compound is applied into the emissive layer, the OLED can maximize its luminous properties as holes and electrons are recombined uniformly over the whole area in an emitting material layer (EML).Type: ApplicationFiled: September 26, 2023Publication date: March 14, 2024Applicants: LG DISPLAY CO., LTD, KOREA UNIVERSITY RESEARCH AND BUSINESS FOUNDATIONInventors: Kyung-Jin YOON, Dae-Wi YOON, Ji-Ae LEE, Su-Na CHOI, Dong-Hoon CHOI, Min-Ju CHO, JiWon YOON
