87‐2: <i>Invited Paper:</i> Recent Progress in Phosphorescent Green Emitters

The fast expansion of AMOLED displays calls for higher brightness, lower power consumption, longer operating lifetime, and wider color gamut. As one of the essential materials in the OLED stack, green phosphorescent emitter plays a key roll in the device performance advancement. Since the first adoption of green phosphorescence in an AMOLED display, great strides have been made on improving the efficiency, lifetime, and line shape. However, further advancement of AMOLED displays require better materials. In this paper, we report on a series of new green emitters recently developed by us to address the issues currently associated with the material. Green emitters developed for P3, Adobe, and BT2020 color gamut will be discussed. We have demonstrated that by employing innovative molecular design, we are able to address the key challenges such as narrow spectra, wide color gamut, and low capacitance, providing a comprehensive solution for the next†generation OLED applications, ranging from mobile devices to augmented and virtual reality systems.
