LCD or Plasma, Which Way To Go - By: Thomas Pretty

With so many different types of TV on the market, the Sony Bravia, Panasonic Viera, the Sharp Aquos. Unfortunately for the consumer deciding which is ultimately difficult, and that is even before the decision over LCD or plasma has been made. The following article intends to highlight the difference between LCD and plasma TV models, how they operate and which can be considered the best option.

Both plasma and LCD TV models look similar, both are stylishly flat and elegant. Both technologies deliver a better viewing experience than the cathode ray tube televisions of old and due to their flat and lightweight nature will save a great deal of space in the home. In addition the majority of plasma and LCD TV varieties offer the viewer a true widescreen experience. This is however where the similarities end; within the technologies at work are markedly different.

The LCD TV, as the name gives an indication of utilises LCD or Liquid Crystal Display technology. Today the Sony Bravia range is made up almost entirely of LCD models, as are most Samsungs. The technology works by using hundreds of thousands of small pixels that change colour as electric current is passed through them. It is only when all of the pixels are taken as one image, and a backlight is used that a picture is formed. It is through the use of numerous voltage changes that the picture changes rapidly.

Plasma TV technology on the other hand uses an entirely different system. Instead of liquid crystals small cells filled with gas, usually plasma or neon are used. These gases alter in brightness and shade when voltage is passed through them, these black and white images are then filtered through different coloured phosphorus gases in order to create a colour image.

These two types of technology have certain benefits and downsides; the following hopes to compare each.

Both LCD and plasma TV models are similar in size and weight. In terms of screen size plasma televisions typically come in larger sizes, even up to around seventy inches. In contrast LCD TV models are available in smaller sizes, although usually they are the lighter of the two types.

Picture quality varies depending upon the environment in which television is being watched. It is generally understood that LCD TVs have problems with black levels, meaning that the shades of black can be limited. However in bright environments LCD televisions perform better whilst plasmas will be better in darkened rooms. In the majority of cases those who watch a lot of films will be better served using a plasma, while regular TV viewer will most likely want an LCD.

Lifespan of the two technologies is probably the largest differing factor. Most experts agree that while some plasmas will estimate a lifespan of sixty thousand hours it is more likely that the television will lose half of its brightness after twenty thousand. On the other LCD TVs can guarantee around sixty thousand hours.

It is hoped this article has helped to clear up some of the issues surrounding LCD and plasma TV models. Whether you choose to buy a Sony Bravia, a Panasonic Aquos, an LG or a Samsung, with a careful approach it should be possible to have years of viewing pleasure.
