What is the difference between an LED LCD HDTV and an LCD HDTV?

Q. The reason I'm asking this, is because I'm going to buy one. But, I don't know the differences between them. Can you guys please tell me the advantages and disadvantages of each one? Also which type of these HDTVs lasts more time and which is more reliable? Last, which of these HDTVs do you guys recommend? Thanks, in advance.

A. The display technology in both types is the same - a Liquid Crystal Display panel. The difference is in the backlight. "Plain old" LCDs use a CCFL (Cold Cathode Fluorescent Light) backlight, while the LED models use LED (Light Emitting Diode) backlights.

LED backlighting typically looks nicer than CCFL backlighting, giving better color range, and in many cases offers a sharper picture.

At this point, I'd go for an LED backlit model if it was available.


Can someone explain the difference between LCD, LED, and Plasma TVs? Also, if 3D TV worth it?
Q. As far as I know, the LED technology was designed to be better than LCDs. 3 years ago, LCD seems to be the top dog in all HDTVs due to the technology and power savings, but as of recently I see people really favor Plasma. From what I understand, the flaws that Plasma TVs used to have have been improved significantly and it's currently the best selection for heavy video gaming as it has much more Hz.

And then there's 3D TVs. To me, 3D is nothing more than a gimmick or fad that will die out pretty soon, but it's been 2 years and almost every major video game support it today. I've never had an experience with a 3D TV besides trying it out for a couple seconds, so I don't know if I should go for it.

I will be shopping for a new TV this Black Friday and am looking through various deals. Right now, I am looking through many deals but can't decide what are the drawbacks from each. My budget is $500 max (without tax and warranty). All things considered (brand, price, size, type, etc.), which is the best pick out of these four?

[1] $299.99 (Reg $899.99) | Toshiba 50" LED-backlit LCD TV 1080p (FullHD) 50L2200U

[2] $479.99 (Reg $679.99) | TCL 48" 1080p 240Hz LED HDTV

[3] $499.99 (Reg $799.99) Samsung 40" 1080p 120Hz LED HDTV with 3D

[4] $497.99 (Current $899.99) | Samsung 40" LED 1080p 120Hz 3D HDTV (UN40EH6030FXZA), with 2 pairs of 3D glasses

Thanks.

A. LED TV's are LED backlit LCD screens that are brighter and arguably sharper than their LCD counterparts. Plasmas have deeper blacks than LCD's and are more for movie watching but if you are into sports then LED/LCD is superior.

I agree with you that 3D is a fad and personally I get sick and develop headaches when looking at the 3D imagery. There have not been enough studies done to determine what long term health effects 3D screens have on the eyes and that alone would be enough to turn me off.
