To enhance the efficiency and stability of quantum dot light-emitting diodes (QLEDs), we meticulously adjusted the energy levels, charge balance, adjacent interfaces, and electronic leakage mitigation. The refined blue QLED demonstrated a T95 lifetime exceeding 80 hours at 1000 nits and achieved a peak EQE of 18.7%.
