Patent Summary

Organic light-emitting diode (OLED) that achieves enhanced efficiency through optimized host material design. The OLED comprises an organic material layer featuring a host material with a specific dopant that enables efficient exciton transport between the host and dopant. The host material's dopant is specifically engineered to balance the energy levels between the host and dopant, ensuring efficient charge balance and maximizing device performance. The OLED's performance is further enhanced by incorporating an auxiliary layer that incorporates the dopant, which serves as an emission pathway. The OLED's design enables improved light efficiency, stability, and lifetime compared to conventional OLEDs.
