Abstract:
Provided is an OLED that includes in its emissive region a first compound, a second compound, and a third compound, where the first compound is capable of functioning as a phosphorescent emitter in an OLED at room temperature, the second compound meets at least one of the following conditions:
(1) the second compound is capable of functioning as a TADF emitter in an OLED at room temperature; and
(2) the second compound is capable of forming an exciplex with the first compound in an OLED at room temperature, and the third compound is a fluorescent compound that functions as an emitter in the OLED of the present disclosure at room temperature.
(1) the second compound is capable of functioning as a TADF emitter in an OLED at room temperature; and
(2) the second compound is capable of forming an exciplex with the first compound in an OLED at room temperature, and the third compound is a fluorescent compound that functions as an emitter in the OLED of the present disclosure at room temperature.
