LED TVs: 10 things you need to know | Fully Equipped - CNET ... Editors' note: Updated June 3, 2010 I've written articles in the past explaining various TV technologies, including the differences between 720p and 1080p and 120Hz and 240Hz LCD TVs. But with Samsung, LG, Sony, and other manufacturers pushing so-called LED TVs these days, it's high time that I--with an assist from our resident video guru, David Katzmaier--sort through all the marketing mumbo jumbo and provide some insight into just what an LED TV is. Here goes. 1. An LED TV is not a new kind of TV. I appreciate a good marketing ploy as much as the next guy, but an LED TV is just an LCD TV that's backlit with light-emitting diodes (LEDs) instead of standard cold-cathode fluorescent lights (or CCFLs).

By Robert Wiley, Senior Editor LED TV is a bit of a misnomer but as manufacturers and retailers continue to use the term, it makes it's way into the public conscience and is worth deliberating on the differences. LED televisions are really just LCD televisions that use LED lights for back lighting instead of the flourescent CFL lighting traditionally used for LCDs. Both employ the liquid crystal diode (LCD) technology front panel containing the “twisting crystals” which define LCD technology. LED TVs feature two main forms of back lighting, edge lighting and local dimming.
Edge lighting has LEDs around the edge of the panel and this allows for extremely thin construction. Lately, through advancements in LED (light emitting diode) technology these lights can be manufactured in very small sizes so even local dimming back lighting LED TVs can have a very thin depth. The Samsung UN55F7100 has excellent color rendition and picture clarity.
