LCD TV

What technology is the TV based on?

Tube- The tube TV has almost disappeared from the market giving room for the more slim plasma and lcd. The main disadvantage with tube technology is that most tubes are fairly cumbersome, so these types of TVs generally take up quite a bit of space.

Plasma tvs are thin and lightweight and capable of being mounted on a wall like a painting. Their main advantage toward LCD is that they are capable of showing a more intense black.

LCD stands for Liquid Crystal Displays. It is a flat panel technology which uses liquid crystals sandwiched between two glass plates. These TVs can be even thinner than plasma screens and they normally use less energy. LCD-technology is the most common technique today.

LED-tvs are newer versions of LCD-tvs that use light-emitting diodes as backlight. This allows them to show black and dark colors more intensively.

Projection-TV use three picture tubes instead of one. A red, a blue and a green cathode ray tube. The advantage is that you can easily project to a large surface area without too much loss of quality. One disadvantage is that it is still very expensive to buy.
