Abstract:
Embodiments relate to a delayed fluorescence compound of Formula 1: or Formula 2: The excitons in the triplet state are engaged in emission such that the emitting efficiency of the delayed fluorescent compound is increased. Embodiments also relate to a display device with an organic light emitting diode (OLED) that includes the delayed fluorescence compound.
