LED televisions are currently LCD televisions with LEDs used as back lighting. They use the same display technology as other LCD televisions but have replaced the CCFL lighting.
There is a new breed of LED television about to be launched. Organic LEDs known as OLED are being developed for a true LED display. Unlike LCD which uses a light behind liquid crystal shutters, OLED televisions use red, green and blue LEDs at each pixel location to generate the color and intensity of the pixel.
OLED televisions are promising to be slimmer than ever before and are likely to reduce build costs in the future. For the immediate future in 2012, expect to be paying a premium for the new LED technology.
LED televisions use light emitting diodes whereas LCD televisions use a liquid crystal display. The majority of people prefer the look of LED televisions because of the application of higher technology in the LED television. The picture quality of an LED television tends to be better and their are more options available when purchasing an LED television.
Both Televisions have liquid crystal display but an LED has a backlight also. That is really the only major difference that I know of at this point in time.
lcd having more life then led.
There's not much of a difference, the quality really depends on the brand. The biggest difference between LED and LCD is that LCD has fluorescent lamps in it and LED has LED lights in the back of the screen.
They dpon't make LED screens yet just LCD and plasma screens.
The difference between a LED and a LCD is that the LED uses back lighting that some say give it a higher quality picture then the LCD TV. Other benefits of the LED is that it is a thinner panel and uses less power to run then the LCD.

They are actually quite similar. LED televisions are actually just LCD televisions that use LED lighting for the back light instead of the traditional fluorescent CFL lighting. http://lcdtvbuyingguide.com/HDTV/led-vs-lcd.html
Same thing except LCD TVs are televisions by themselves while LCD monitors can serve as either a television OR a computer monitor.
Basically ,LED stands for Light Emitting Diode and LCD stands for Liquid Crystal Display. LCD TV use fluorescent lights while LED TV use those light emitting diodes. The fluorescent lights in an LCD TV are always behind the screen. On an LED TV, the light emitting diodes can be placed either behind the screen or around its edges. In my opinion ,LED TV is more efficient than LCD TV
An LCD TV is exactly an LCD screen with fluorescent lighting shining through it. Without the light, you could see very little on the screen. An LED TV is exactly an LCD screen with LEDs behind the LCD screen shining through it. The LED lighting gives more even color and brightness on all pixels, and results in a sharper image with more 'pop'.
Televisions can be compared on the Samsung website. There is a page describing the difference between LCD, LED, and Plasma so that you can determine what you need or want.
LED televisions are lit wit LED and LCD televisions are lit wit fluorescent lighting. The biggest difference is the picture appearance. LED televisions have a slightly better picture quality but there are pros and cons to both types. You can read reviews at CNET in order to decide which would be best for you. As far as purchasing an LED television goes, you can find them almost anywhere that and LCD television is sold. Best Buy or Amazon.com are just two of the many choices you have in making a purchase of an LED television.
LCD are little lights for each and every pixel, while plasma has two pieces of glass with plasma between the two.
