The Lurks And Perks Of Led tvs

Plasma is a very well-known, although fortunately little-bought, television technology. There are some wonderful models out there, that have drool-worthy resolution, colour saturation and contrast ratio stats. If you also enjoy owning expensive items for the sake of it, plasma televisions have a much higher ‘friend-envy' factor. However, unless you buy top-of-the-line models, there are quite a lot of technological issues to be found in plasma televisions. We look at when the model is preferable to LCD televisions, like favourite Samsung TVs and other big brands, and when LCD wins out.

How do plasma televisions work?

Plasma televisions have thousands of tiny cells in the screen – each pixel is divided into three cells, one coated with red phosphors, one with green and one with blue. These cells are filled with a plasma gas, and spanned by electrodes. When electricity is applied, the plasma gas gives off electrons that excite the phosphors, making them glow. The technology is inherently different to LCD televisions, and has vastly different benefits and drawbacks.

The Perks of Plasma Technology

If you are willing to spend the necessary dollars to make the potential of plasma a reality, the reward is amazing picture quality, in terms of colour saturation and contrast ratio. Unlike LCD televisions, light cannot ‘leak through switched-off pixels, so blacks are inherently ‘blacker' than in LCD Samsung TVs, Sony TVs or Sharp TVs – the phenomenon of leakage in LCDs is model-independent. However, there are some big drawbacks to buying televisions that use plasma technology.

The Lurks of Plasma Technology

If picture quality is high on your list of must-haves for buying televisions, plasma will be a major contender in the race for your TV dollar. There are plenty of other considerations to be made before buying, though:

* The technology is not inherently perfect. Lower-priced sets are almost invariably much lower quality.
* Plasmas are subject to screen burn-in, so if you watch one channel consistently you might get a ghosted version of their watermark while watching other channels.
* The brightness starts to diminish from the moment you turn the screen on. The half-life of the screen is around 10,000 hours, so after three years of average viewing the plasma screen will be down to half its original brightness.
* Early models of cheap plasmas have a screen resolution around 30% lower than cathode ray tube sets
* If you consistently watch television in a brightly lit room, the display resolution drops enormously – to a level where an old cathode ray tube set would be classed as irreparably faulty.
* The power consumption compared to a similarly sized LCD screen is huge – around double the figures for LCD in most cases. This quirk of plasma technology has led the EU to consider banning the technology, and Australia is said to be considering it also. While early indications are that the market will be left to its own devices to sort out what consumers want, the fact that legislative action is being considered should act as, at least, a warning to potential purchasers!

LCD televisions are cheaper, more reliable and durable, more future-ready, and take less energy both to run and to manufacture than plasmas do – although contrast ratio and colour saturation shows definite improvements in plasma televisions. If you are buying a television and looking for a good all-rounder, go for an LCD; if you are willing to sacrifice long-term quality and quite a few dollars for better colour and contrast, plasma should be your choice.

Plasma vs. LED vs. LCD TV's?

I'm trying to decide which is best for me to purchase. I'm in the market for a mid-50" Flat Screen Tv and have been reading over some articles comparing these three types. Seems Plasma has the advantage in contrast ratio, viewing angle, etc. but doesn't have much life span. Give me some opinions, which is best?

Plasma all the way-I have the 50" Viera and love it
Plasmas do not suffer from Burn in and more-the Viera has a pixal orbiter and other anti image retention things-this thing has been on every day for 2 years and during the day the tv basically stays on nick or nick jr- no logo burn in yet- also when Gears of war 2 came out it was on Gears with out being turned off for a week straight.
No other tv type give you a better picture[ just research consumer reports and other audio visual mags no other type can match plasma black levels
No motion blur-plasma refresh rate is 600Hz while most lcds are 60hz and the top of the line ones go up to 240Hz
Plasma do use more power but its not like your power bill is going to go up

LED tv are just LED back lit LCD tv
