LED TV vs LCD TV

What is the difference between a LED TV vs LCD TV? This will be the big question in 2011-2012 and most likely for years to come when shopping for a new tv is often the simplest to answer.

Shockingly enough you would think the big brand name stores would have a little something for you to read in the tv section to explain such things, but they don’t. Your often required to track down a sales person who explains things so fast and then moves on to trying to sell a TV to you.

Your other option is the turn to the internet. And it’s here that you’ll find the best answer to the “LED TV vs LCD TV” question. And you’re here now, so let me get it.

First there is no such thing a pure LED TV. LED stands for Light emitting diode. and LCD stands for Liquid Crystal Display. LCD is referencing the screen of the tv, and LED is referencing the lighting of the TV. Every flat screen tv made today (excluding plasma tvs) are LCD TVs. Simply meaning the HDTVs you see today are tvs that use a liquid crystal display for the screen. That’s all.

Led tv vs Lcd tv – backlighting

The old technology of the LCD tvs is to use a fluorescent lamp in the back of the TV to give the light. Usually this light is pure white. When you tv is hooked up and receiving channel information (lets say you’re watching NCIS), then that show is sending voltage information over the cable line or antennae to your liquid crystal display (LCD screen), that information is telling the LCD screen to use certain colored filters, and it does it fast.

LED TV vs LCD TV put in a different way

Another words. You have three pieces of colored glass. Red, blue, and green. You can’t see this glass no matter what color it is without light. Right. So backlighting is needed. Now if you look through each piece of colored glass you will see the color of the glass using the light around it. Look at a string of Christmas lights. The actual bulb is giving off white light, but it’s the glass or plastic around it that is colored that is making it appear different colors.

LED TV vs LCD TV – color filtering

So you have the principle of it all. The voltage comes in the TV, the tv can read the different color filters it will need for each pixel of the LCD screen. In a time that you can barely blink, the LCD tv is filtering and filtering giving you the different colors. When dealing with the LED TV vs LCD TV debate, is the only difference between the old LCD technology that uses a fluorescent backlight to give light to the filters of the TV, is that now they are using LED lights for the back lighting. That is all it is!

So the big questions between LED vs LCD TVs is just about backlighting?
YES. The reasons are a few, and you’ll see it makes sense.

Using LED backlighting you can make the hdtv slimmer, smaller for that matter if you want as well.
LCD/LED tvs use less energy to run over your standard LCD/fluorescent TV. Which saves you money, A lot of money actually. The LCD/LCD tvs can use as much as 2 times the energy than the LCD/LED TVs. This is a big difference in the LED vs LCD battle.

LED TV vs. LCD TV – Led Backlighting

To take advantage of the new led backlighting new and improved LCD screens are coming out to accompany it. These screens recognize the voltage and wavelength much faster and can change color much much faster resulting in a picture perfect image on your screen. Another words when talking about LED TV vs LCD TV the LCD with LED backlighting is the new player on the block that offers faster picture so the action never gets blurry.
