SDK) has made remarkable progress in its development of organic electroluminescent (organic EL) device technology based on an innovative singlelayer organic electroluminescent devices based on phosphorescent polymer materials, achieving the world's highest external quantum efficiency of 17% for green light and 16% for blue light, respectively, with durability of 350,000 hours (initial luminance: 100 cd/m2). The responsivity measurements from HACR are simply scaled to external quantum efficiency [n. The device also exhibits a high luminous efficiency of 65 candela per ampere (cd/A) and an external quantum efficiency of 18%, at 1,000 cd/m2, both characteristic features and benefits of phosphorescent OLED technology. |
