A high performing blue QLED device has been developed synergizing high color gamut (yCIE<0.06) colloidal blue QDs and device optimization with balanced charge carriers. To realize high color gamut blue QLEDs, a novel blue QD structure has been designed with enlarged particle dimension. Such improvement could raise the valance band for 0.2 eV, which significantly lowered the hole injection.
