What you need to know about LCD, LED, and Plasma TVs

Q: What is the difference between an LED, LCD, and Plasma TV?

A: The first thing we need to discuss is the LED. LED stands for Light-Emitting Diode. They are very energy efficient and small so this is why you can have those ultra think LED TVs. The key here is that an LED TV is still an LCD TV though. The key here is that this particular type of LCD uses the LEDs as a light source. This will make sense once we get into what an LCD is.

An LCD, which stands for Liquid crystal display, is a device that, more or less, can change color and show images thanks to a light source. I would highly suggest reading LCD to get a more specific definition but the key here is that it does not use much electricity and it is light. So when combined with the LED light source you can end up with ultra thin TVs.

A Plasma display is made up of two panels of glass that have pixels which hold gases. The gas in the cells or pixels are turned into plasma and that plasma is used to display the images. This is why they are called plasma displays but again I would highly suggest reading Plasma display to get more detailed information.

The key here is that LCDs have come a long way. Plasmas were once the best displays you could get because they could be made bigger than LCDs. Now that LCDs come in any size they have started to take over the market. With the advent of LED LCD displays, which means ultra thin and stylish displays, we now see the LED LCD displays taking over.

The thing to keep in mind when looking at these TVs/displays is that the older style (ie thicker) LCD TVs are going to be about 1/2 the price of the newer LED LCD TVs. So if you want the best bang for your buck then you want to stay away from LED LCDs. If you want the most updated technology then you will want to go with LED LCD TVs.

Hopefully this gives you a good overview of the different technologies and a good place to start off your research.
