Paper Abstract

In this paper, two approaches are demonstrated to narrow phosphorescent OLED (PHOLED) emission lineshapes to increase color saturation while keeping device high efficiency performance, which is critical for large area flat panel displays. One approach uses bottom-emissive microcavity structure in green and blue devices to achieve 22 nm full width half maximum (FWHM) emissions. The other approach is to reduce the natural width of the emission as exemplifying in a red device. A new NTSC red with 64 nm FWHM emission is reported. In a standard device, it has a luminous efficiency of 18.3 cd/A at 10 mA/cm2.
