LED and QLED TVs are similar to each other as they each use LCD panels with LED backlights; the only difference is that QLED TVs use a quantum dot layer that allows them to produce a wider range of colors. OLED panels are completely different, as the pixels are self-lit and can turn themselves off when needed, allowing the TV to produce perfect blacks.
QLED is just a marketing term to signify that the TV uses a quantum dot layer. A few companies, like Samsung and TCL, officially label their TVs as QLED. Other manufacturers like Vizio and Hisense use quantum dot technology, but don't use QLED in their marketing. To make things even more confusing, LG is releasing quantum dot TVs, marketed as QNED. Whatever these TVs are called, they all fall into the same quantum dot category. LED TVs use the same backlight as QLEDs, but they don't have the quantum dot layer.
