If we're talking new TVs, then there's really only really two technologies. It's either OLED or LCD.
OLED is the spiritual successor to plasma. In both technologies, the light source is the pixel itself.
For LCD, the light source is a separate element. In older LCD TVs with a thicker back, the light source was miniature fluorescent tubes. When LED lighting got good enough to be used, that's when you started to see the change to TVs being marketed as LED.
The most striking difference was the thickness of the TV. They no longer needed to be 7-10cm thick to accommodate the florescent tubes, so we started to see screens reduce their depth down to a couple of centimetres. Your Samsung LED TV is - like most TVs sold today - an LCD set with an LED backlighting system.
There are differing types of LCD panel. Quantum dot is a bit of a marketing term to make the acronym QLED which looks very much like the acronym OLED. The actual tech though is genuine. It does perform better than a common VA or IPS LCD panel.
