5.1: Fluorescent RGB OLEDs with High Performance

Abstract

Abstract We developed highly efficient fluorescent dopants for full‐color OLEDs. For blue, green and red OLEDs, current efficiencies of 8.7cd/A, 20.5 cd/A and 11.4 cd/A at 10mA/cm 2 were achieved, respectively. Lifetime of the blue device was estimated to be 23,000hours at an initial luminance of 1,000 cd/m 2 . Moreover, long lifetime of 100,000 hours was estimated in the green and red devices. By the use of these dopants, we expect that a full‐color OLED display with the lifetime of 18,000 hours at a white luminance of 300 cd/m 2 can be achieved.
