There appears to be a lot of confusion over the new so called "LED TVs" made by Samsung and others. First of all, these are NOT really LED TVs! They really are standard LCD (Liquid Crystal Display) TVs but they use LEDs (Light Emitting Diodes) to back light the LCD screen. Up until now, most LCD TVs use Cold Cathode Fluorescent Lamps (CCFLs) to back light the LCD screen. There are many potential problems with CCFLs with the biggest ones being Black Levels and Power Consumption. Since you can't really dim a CCFL, you never get very good black levels so dark scenes tend to lack detail. Manufacturers have learned some tricks to make this better over the years, but LCD is still lacking as compared to Plasma Displays. So LCD TVs that use LEDs use less power and have the POTENTIAL to have better black levels since LEDs can be dimmed or turned off very quickly. But as always, make sure you view any TV before you buy it to verify the picture quality. So why wouldn't you buy an LED  backlit LCD TV? They are thinner, use less power and have better black levels.. Well they are much more expensive than a standard LCD TV so you have to decide if it is worth the extra money. Of course over time, as the volume goes up and competition increases, prices will come down on these models. Comments?
