Ultra-wide Color Gamut OLED Display using a Deep-red Phosphorescent Device with High Efficiency, Long Life, Thermal Stability, and Absolute BT.2020 Red Chromaticity

摘要

We developed a deep-red phosphorescent organic light-emitting diode (OLED) with (x, y) chromaticity coordinates of (0.709, 0.290), high external quantum efficiency of 27.4%, and higher stability than a conventional red OLED. This device realizes an OLED display with a color-gamut ratio of 101% to the BT.2020 standard.
