The biggest difference between an LCD and LED television is in the lighting. Both televisions have a liquid crystal display, however, with the LCD the lighting comes from fluorescent lamps behind the screen and with the LED the lighting comes from light emitting diodes behind the screen.
Currently, LED televisions are in fact, LCD televisions. LCD technology uses a light behind the liquid crystal layer and the image is formed when the crystal shutters open to allow the light to pass through. Until now, most LCD television used cold cathode lighting (a form of fluorescent lighting). An increasing number are now using LEDs as the illumination. The light source is more efficient than cold cathode but the LCD technology remains the same.
True LED televisions use the LEDs in groups of three, red, green and blue for every pixel. The LEDs turn on and off to generate the color and brightness for the pixel. This avoids the need for separate control ad illumination layers and allows the screen to me even more efficient and even thinner. Thicknesses of less than 5mm or 1/4 inch are possible.
The use of organic LEDs (OLEDs) is allowing manufacturers to produce high densities of LEDs to deliver full resolution screens. Currently, in 2012, there are only a handful on the market and they are breathtakingly expensive. Expect availability to improve dramatically in the next year or two and for the prices to fall as well.
lcd tv's are the ones made of liquid crystals when an electric or magnetic impulse falls on them they reflect light. while the led's are light emitting diodes
Nothing. All led TV's are just lcd back lit by led's
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'.
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.
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.
LCD are little lights for each and every pixel, while plasma has two pieces of glass with plasma between the two.
