What is the difference between an LED and LCD TV?

LED TV is just an LCD TV that uses a LED backlight instead of a fluorescent one. This helps alleviate the problem of poor color fidelity that LCD's suffer from, but does little to help poor black levels, response time, and viewing angles.

At around 20 inches, I would recommend a CRT for best picture quality. Resolution is NOT everything. Most people think resolution is a lot more important than it really is. So as long as space isn't a major constraint and you're not going to be using as a computer monitor, I'd recommend a CRT at 20 inches: where it lacks in resolution it more than makes up in response time, color fidelity, and contrast. Plus it costs up to 50% less than a comparable LCD.

http://www.memorex.com/products/product_details.ph... This is one of the better 20 inch CRT's currently on the market. $160 at Target. I own one and am very satisfied with it. It's got 10 watts of power output, which is not only excellent for a TV of that size, but respectable for ANY sized TV.

LED is a type of LCD. "Regular" LCDs use CCFL (flourescent) light source as their backlight. LED LCDs uses LED light source as their backlight. This provides the LED LCD set better blacks, colors, contrast, and more even image across the panel. So in theory it is definitely a better picture. Also it consumes less energy. But at the current time, you pay a huge price premium for these features. Frankly you're better off, financially, going Plasma over LED LCD in the current landscape.

As for lasting over time, both CCFL and LED are equally reliable in that sense. You need to dig in to the tech specs and look at how many hours the TV is rated for, not what kind of backlight it has. 60,000 hours equates to 20+ years at 8 hours a day, 365 days a year.

Also, TV size matters. You don't really need to worry about the kinds of things LED LCDs improve until you break 40" and maybe moreso 50". You just don't get to see/enjoy many, if any, of the advantages of the more advanced technology on smaller screens. I'm sure it would be better than a CCFL, but just not enough to warrant the price increase you would have to pay. Right now I'm not sure you could even find anyone manufacturing a 20" LED set anyway.

If you went LED LCD I would go with either Samsung or Sony right now. Its still fairly new and those are the two top dog manufacturers, so I'd put more faith in their products. I wouldn't both going LED LCD if you couldn't get a set from one of them.

In the 20" inch sort of range I would look at Samsung primarily. They are the world leader in LCD technology. They make the best panels and compete neck and neck with Sony for the best image processors. If you got up to 26" or higher, I would then throw Panasonic into the mix. For 26" - 37" I personally prefer the Panasonic LCDs over any other brand. I think they deliver the best image. They don't make sets under 26", but Samsung does.

The difference lies in the backlighting. Normal LCD's use a different backlight than LED's. This artical is really usefull: http://www.audioscreens.com/?p=37

LED is the lastest technology,It come excellent picture quality with more mega dynamic contrast ratio,thinner set only 1.2 inch and 40% less power consumption than LCD.But the smallest size of LED TV is 40 inch and Samsung or Sony are great brand.However I would recommend Samsung over Sony,it come with better features and cheaper price.

for around 20 inch you should go with lcd tv.Samsung LN22B460 22-Inch 720p LCD HDTV is a good choice

LED's are light emitting diodes. LCD is a liquid crystal display. LED's take a whole lot of power and the physical size is large compared to LCD. This means that HDTV is probably only in the realm of LCD tv.

The war at the moment is between LCD and plasma. I've never heard of an LED tv.
