A highly efficient OLED lighting product using all‐phosphorescent technology, for the first time in the world, is presented. Using proprietary blue phosphorescent emitter, 45 lm/W white emission is achieved at 2800K color temperature. The produced panel has very low driving voltage and small color shift regarding the viewing angle. The successful commercialization of all‐phosphorescent technology would bring great power saving feature for OLED to compete with other technologies.
