Abstract We demonstrate a three‐component RGB phosphorescent white OLED with efficiencies of 38 cd/A, 18.4 lm/W, and 16% EQE at 1000 cd/m2 and CIE coordinates of (0.39, 0.39). The CRI is 79, indicating good suitability for use in full‐color LCD backlights and OLED displays based on RGB color filters. High performance is attributed to use of all phosphorescent dopants (red, green and blue). To the best of the authors' knowledge, this device is the highest efficiency white OLED reported to date in the literature.
