P-145: A Three-Spectrum White Organic Light Emitting Diode Base on a New Red Organometallic Iridium Complexes

We develop a three‐spectrum white OLED (WOLED) made by a new red phosphorescent dopant material. The red dopant material is phenyl‐qoinazoline framework organo‐iridium complexes. The RGB peaks of WOLED are at a wavelength of 450nm, 512nm, and 633nm, respectively. However, The RGB peaks of WOLED are at a wavelength of 450nm, 512nm, and 572nm, respectively, when the red dopant material is replace by DCJTB. Therefore, The former WOLED of RGB spectra are the most distinct than the later one. The former WOLED has efficiencies of 10.62Cd/A, 6.07lm/W at 100 Cd/m2, and CIE coordinates of (0.28, 0.38). It is good suitability to use in OLED displays based on RGB color filters and full‐color LCD backlights.
