There is an awful lot of misinformation here. I have the best TV ever made the Pioneer Elite Kuro and have yet to see any LCD that's remotely watchable. LCD suffers from poor viewing angles, cartoonish inaccurate colours and motion lag. LED sets are simply backlit with LEDs rather than CCFLs and may some have local dimming which will drive you crazy and some don't they also come in all white or RGB but regardless they are all LCD TVs. OLEDs will be a true LED set but the tech isn't ready yet as even a 20" is many thousands of dollars. For good information read up at avsforums.com. Just to clarify a 600hz plasma is a totally different specification than a 120/480 refresh rate on an LCD and one has nothing to do with the other. When Pioneer announced they were getting out of plasmas, they lost $500 on every set due to their advanced tech, I bought 4 of them and have turned down $12,000 offers for what was a $7K set.
