Perspective: OLED Displays Singing with the Blues
Advanced Materials, EarlyView.While blue pixels consume approximately 50% of the energy of OLED display front planes, in the 25 years since their invention, 100% internal efficiency triplet‐controlled phosphorescent OLEDs have not met the stability standards necessary for their adoption.

Effect of Host Anisotropy on Phosphorescent Emitter Orientation and Light Outcoupling in OLEDs
Advanced Optical Materials, EarlyView.The orientation of the emissive transition dipole moment of a cage‐type Iridium complex can be tuned by the anisotropic alignment of the cohost material, which is expressed as the S$S$ parameter of the film. Thus, the external quantum efficiency of OLEDs can be further enhanced to reach values above 30%.
