LED, LCD and Plasma Televisions.

LCD, LED and plasma televisions sets have largely overtaken the original CRT displays, and the main difference is how the light and images seen on the screen are captured and generated. 
LCD televisions replaced the old style and were a vast improvement on the way that the picture was displayed. LCD actually stands for Liquid Crystal Display, and it is the molecules of the crystals that are used to create a sharper, higher definition picture. The LCD televisions tend to be flatter, lighter in weight and have far more screen size due to the slenderness of the frame surround. LCD televisions have excellent colours; 256 in fact for each of the red, green and blue pixels. The more recent models actually last around 60,000 hours, which for the average television viewer is approximately 20 years. However, LCD’s struggle to achieve pure black or white picture quality and may not be as good as they actually should be. 
The pictures shown on Plasma television sets are actually created using gases which contain xenon and neon atoms. Due to the technology used plasma sets will show a massive variety of colour and unlike LED or LCD they are able to show true to form black image quality. A plasma television may be the best for you if your seating is situated around the sides of the room and not only directly in front of the set. This is because LCD sets have narrower viewing angles when compared to the plasma sets, and your viewing pleasure is not affected when watching a plasma TV from the side or at an angle. Due to the gas used in plasma however, the life of the television set may only be around eight years, and these gas particles that are used are not as yet refillable, although with technology advancing ever onward, this is no doubt set to change in the coming years. One slight disadvantage of plasma televisions can be a "burning" screen. This means you can still see the previous image even though it is no longer on the screen. To help prevent this, always switch your television set off when it is not in use and don't leave it on for long periods of time.
An LED television - which stands for Light Emitting Diode - is a very popular choice. LED televisions are lit with the LED's at the back or edge and the fast time that it takes to switch it on or off makes for a high resolution. These advances in the technology have made LED televisions very slim and very powerful, which turns out to be not only a space saver in your home but also very energy efficient. Unlike plasma, LED televisions are available in an extremely wide range of sizes, from portable 19 inch right up to spectacular 60 inch sets. Many of the LED sets come complete with ports for USB's or HDMI cards, meaning that you can use your television for gaming or viewing photographs with an excellent image quality.
