Abstract: An OLED includes a suppression mechanism and multiple dopants in its organic emissive layer. The organic emissive layer includes a host, a first compound capable of phosphorescent emission at room temperature, and a second compound capable of phosphorescent emission at room temperature. The suppression mechanism is capable of preferentially reducing the emission of light emitted by the second compound. The organic emissive layer may also contain a third compound capable of phosphorescent emission at room temperature.
