the difference is not to major between an led an a lcd the screens are almost identical the major difference is the lcd uses stripe lighting to illuminate the picture but the led uses led bulbs thousands so the picture is brighter an more graphic. the down side is the screens only last bout 40000 hours as the blues pigment goes. but tbh thats bout 8yrs of on every single days every hours. an as for led vs plasma led all day an samsung is the best choice in my opinion

hope that helps alil
