The study presents a novel approach to enhance blue MR-TADF OLEDs' efficiency and color purity using tandem device structures. By employing TBN-TPA as the blue MR-TADF material in tandem OLED devices, narrow-band emission and high color purity were achieved through optical interference and microcavity effects, aligning with BT 2020 standards. This advancement underscores the potential of tandem architectures and MR-TADF emitters in developing high-performance OLEDs with both high efficiency and wide color gamut, suggesting further research in optimizing tandem structures and MR-TADF materials.

How Setfos was used

Setfos software was utilized to simulate optical and electrical characteristics of OLED devices, particularly analyzing spectral enhancements, microcavity effects, and interference within the tandem OLED structures, to predict and understand device performance improvements, including color purity and efficiency.
