You're probably refering to LED-backlit tv's. These tv's have back lights that are made up of either an "edge-lit" design (Samsung luxia 6,7,8 series) a "full array" design (sharp LE700 series) or a "full array w/local dimming" design (LG LH90 series, samsung 8500, SONY XBR8). The edge-lit design are exactly what they sound like, led's arranged around the perimeter of the screen with a light diffuser sheet to carry the light towards the center. These designs have major flaws when it comes PQ but the design allows for incredibly thin panels. The full array led back light panels operate exactly like ccfl lcd's that we've had for some time now, but power consumption is greatly reduced and there is no Mercury contained in the light source. The full-array back lights with local dimming sets are leaps ahead of even the best LCD's that use ccfl. They can dim and shut off sections of their back light depending on what is being shown on their screen at the time. For example; you're watching a sunset beach scene with a darkened cave systems off to the left, the back light behind the darkened cave system will shut off while the rest of the screen stays lit to give you incredible inky blacks and vivid colors that were just not possible on the last generation of LCD's.
The half-life(time till you are receiving half of the output of the bulb rated) of these back lights is probably around twice that of a standard ccfl back light, around 100,000-120,000 hours. You will probably end up with a new set WELL before your back light fails on these!
