Q.
A. LED TV is a marketing term, and really just causes confusion in the marketplace. The display technology is *still* the same LCD as the LCD TV you could have bought previously.
The difference is in the backlighting. LED TVs use LEDs (light emitting diodes) to light up the screen, compared with "standard" LCD TVs, which use CCFLs (Cold Cathode Flourescent Lamps) to light up the screen. LEDs produce better whites and lights than CCFLs. They're also much more compact, which accounts for the difference in thickness between the two styles of LCD.
Plasma TVs are a completely different technology, using electricity to create plasma from noble gases between 2 glass plates, which in turn create UV light that excites various phosphors which in turn produce light in the visible spectrum. Yes, it's that complicated. Many claim plasma produces truer colors than lcd, though I can't really tell the difference, personally speaking.

what is the differences between a LCD HDTV AND A LED HDTV?
Q. I was told that the shiny screen would not be good if I have lots of windows as it causes more reflections, is this true?
A. The LED that are out now such as the Samsung 6000 series television are still LCD tvs. The panel is an LCD panel and is almost exactly the same as the Samsung 650 series lcd. The major difference is that the backlight is different. The backlight in a standard lcd is a flourescant type of backlight while in a LED it uses Light Emitted Diodes to enhance the picture. An LED will have a higher contrast ratio (black to white level in turn effects colors) than a standard LCD.
