Optimizing transparent quantum-dot LEDs on plastic substrates: enhancing performance through dielectric/metal/dielectric electrode design

초록

This study explores the optimization of transparent quantum-dot LEDs (TQLEDs) on polyethylene naphthalate substrates, focusing on dielectric/metal/dielectric electrode structures. By employing MoOx/Ag/MoOx and WOx/Ag/WOx as the cathode and anode, respectively, we demonstrated enhanced device performance through precise control of the WOx layer thickness, significantly improving luminance and efficiency. These TQLEDs exhibit superior light emission comparable to opaque quantum-dot LEDs while ensuring transparency, which is crucial for automotive and architectural applications. Our findings highlight TQLEDs' potential as a next-generation technology for flexible, transparent displays.
