| contents | Top-emission quantum dot light-emitting diodes (QLEDs) have been extensively studied due to their potential application in augmented/virtual reality. Particularly, the impact of Fabry-Pérot resonance on top-emission QLEDs has been investigated through both experimental and theoretical studies. Additionally, multi-beam interference effects in QLED emission layers have been explored theoretically. However, previous studies predominantly rely on simplified simulations or governing equations with minor numerical corrections, often resulting in discrepancies between theoretical predictions and experimental results. Notably, a comprehensive investigation of multi-beam interference effects remains insufficient.
This study aims to perform a theoretical analysis of multi-beam interference, substantiated with numerical simulations. Specifically, we examine Fabry-Pérot resonance effects and compare them with interference between upward and downward emission components in QLED layers. The findings are expected to provide insights into designing more efficient QLED architectures. |
