Abstract
A quantum-dot (QD) light-emitting diode (QLED) device has a multiple-layer active emission region. The multiple-layer active emission region has n QD layers interleaved with (n−1) quantum-barrier (QB) layers where n is a positive integer greater than one, such that each QB layer is sandwiched between two adjacent QD layers.
