I think the confusion comes from the impression that quantum dots can be individually controlled like pixels in OLED/plasma. But quantum dots are are actually a "dumb" film which converts blue backlight into a RGB components similarly to how phosphor works in LED light bulbs. Of course QD can improve color gamut and brightness but it is still just an improved LED panel. The name QLED tries to confuse people into thinking that it is somehow similar to OLED but they are completely different technology.
