According to Synovate research participants: (UK, France and Germany)

65% favour Plasma over LCD for best Colour Quality

61% say Plasma delivers the best Sharpness Quality

62% indicate that Plasma has the best Response Time

72% deem Plasma to have the best Black Quality performance

facts and myths:

Response time (Motion)

Myth
Flat TVs have trouble retaining resolution when displaying fast moving images.

Fact
Plasma TVs can present moving objects without loss of crispness or detail.Plasma technology needs only one impulse per pixel to produce an image therefore its response time is almost instantaneous.

LCD technology requires pixels to go from active ? to inactive -and back to active again, to achieve a single response cycle; their response time can measure anywhere between 4 milliseconds to and 25 milliseconds. Even the fastest LCD screens can suffer with some degree of movement blurring.

Viewing angle

Myth
Flat TVs have poor viewing angles, meaning pictures lose much of their quality unless you?re sat directly in front of the screen.

Fact
Plasma TVs can actually be watched from very wide viewing angles without any significant loss in colour or contrast, thanks to the fact that they emit light directly from each of their screen cells or pixels.

However, LCD pixels merely ?pass on? a light originating from a single point behind them, therefore LCD screens can lose contrast and colour if watched from angles as small as 45 degrees.

Screen burn

Myth
Plasma TVs are seriously prone to burn in.

Fact
In the early days, plasma TVs were susceptible to screen burn. However, this issue has been largely eliminated thanks to greater use of built-in screen-saving systems and major phosphors improvements.

Example
You can now play computer games or watch logo-heavy channels (e.g. CNN) on a plasma TV without worrying about various static image elements being on the screen for a long period of time.

Energy use

Myth
Plasma TVs use more power than their LCD rivals.

Fact
The reality is that plasma TVs don?t necessarily use any more power than LCDs ? a fact which makes perfect sense if you think about how each technology works.

Plasma TVs, for instance, require just a single ignition of a plasma cell to cause a pixel to illuminate. Since darkness is achieved in plasma pixels by stopping electrical current getting into them, it follows that plasma TVs need relatively little power to reproduce dark scenes.

LCDs by comparison run at a constant power regardless of whether a scene is dark or light, due to their use of an always-on backlight.

Results from an independent research conducted by the AVT.O.P. Messetechnik laboratory in Germany, showed that plasmas tend to use the same ? and sometimes less ? amounts of power than LCD screens.

Lifespan

Myth
Plasma screens have a shorter lifespan than LCD screens.

Fact
Plasma TVs actually have a lifespan that?s at least equal to that of LCD TVs. TVs using either technology will provide at least 60,000 hours of life under normal viewing conditions before they lose more than half their original brightness. This translates to 27 years of continuous viewing for six hours a day.

Plasma screens can actually be made to last even longer depending on the picture settings you use. For instance, keeping the contrast low could potentially extend a plasma screen?s life.

End to end production

Myth
Plasma and LCD TVs alike are built using bits and pieces sourced from a variety of different manufacturers.

Fact
Generally, Plasma TVs tend to be developed and built completely ?in-house?.

In the early days of plasma TV, most manufacturers tended to develop their own plasma research and technology, leading to a situation where many companies now have plasma production as an integrated business model. This means that from the panels to processing, plasma screens are generally made entirely within each particular company, giving them total control over the quality of their products.

LCD TVs, on the other hand, are generally built by using a variety of third-party components, with all the quality assurance issues that entails. And even more confusingly, LCD TVs are traditionally ?OEM?d? ?some companies buy them from another manufacturer and simply put their own brand logo on them. So with LCD, the name on the front of the TV screen you buy may not necessarily be the name of the company that built the main part of the product.
