First of all, you are partially right to be so clear that it's LED. However, the new LED tv's Samsung is making are LED LCD tv's. That's right. conventional LCD tv's are backlit with a CCFL (basically fluorescent lighting). The LED ones use LED's for the light source. Liquid Crystal Displays (LCD's) do not create light, they adjust it (as in color or blocking it altogether). Now, samsung has two kinds of LED-lit tv's. There are backlit and edgelit versions. The edgelit seem to be a little less expensive and much thinner (1.2 inches!) but don't get as black. One of the big keys that plasma has always had over LCD is the deep, inky blacks. This is because in a plasma, the gases are excited to cause the color and the light, or not, causing an actual absence of light. in conventional LCD displays, the light is always on and the liquid crystals are adjusted to block it in dark spots of the screen. with LED BACK-LIT (not edge-lit) displays, the led's can be locally dimmed to help achieve those deep blacks, much like plasma displays are so famous for. So far as I can tell, either type of LED-lit tv should perform at least as well as plasma in any topic with the exception of black levels. Many might say that edge-lit displays don't have as deep of blacks as led-back-lit or plasma displays.
I wouldn't be surprised if over time, most every LCD display drops the fluorescent lamps and goes the way of LED-lighting (some back, some edge).
