Though both LCD and plasma displays are available in the form of thin flat panel displays, but from the technological point of view, these two flat panel displays process the image differently.
Plasma uses a matrix of tiny gas plasma cells charged by precise electrical voltages to emit light, thus creating the image image. Liquid Crystal Display (LCD) - the job of capturing a liquid crystal solution between two sheets of polarized glass. When an electricCurrent passes through the liquid crystal changes the polarization of light through them, in response to voltage - as a result, more or less light can pass through the polarized glass on the face of the display.

It should not be beyond the scope of this article, the actual details, how do these different display technologies process the image - after all, what matters is not what is happening behind the screen, but rather how these differentdisplay technologies work as a TV screen. At the same time, it's worth it is these differences that give each of these display technologies, their strengths and weaknesses, and that makes them suitable than others in certain circumstances.
The following list shows the main differences between these two flat-screen technologies:
Size: At the time of the collision between the plasmaLCD TVs and TV into an experience of 40 to 50-inch screen. In fact, most LCD TVs up to 50 inches, larger screens are also available, although the choice is still very limited. This means that for anything bigger than 50 inches, a plasma display is the only real option if what you are after a direct-view TV system. On the other hand, the smaller end of the spectrum, namely 15 "to 36" LCD TV to go away, what if you want something stylish and slim (less than 4 inchesin depth).
Price: This field is leveling at a fast pace. Until very recently, plasma was the obvious choice for all screen sizes where collision occurs between these two technologies, it is no longer the case. In general, plasma still leads by a good margin only on the largest screen size - 50 inches and up. In order for small (up to 44-inches), starts the price advantage when it comes to plasma vs LCD TVs, LCD shift more towardsTV.
General statement of power: Both plasma and LCD flat-screen TFT last is able to superb image quality - with bright, sharp images. However, plasma screens are best suited for a basic use of LCD home theater. The cell structure of gas inside a plasma display is such that it does not lose light between adjacent cells (or pixels). This renders plasma displays capable of displaying deeper blacks - and therefore moresuitable for television and film where the scenes showed a lot of dark and light content simultaneously.
In comparison, the nature of LCD technology - means that it is difficult for him the true blacks (ie true absence of light) to get as there are always some light leakage from neighboring pixels - where a backlight shines through the LCD layer.
This does not mean that LCD panel s are not suitable as TV screens, LCD panels today use very high contrast, which are ableDisplay blacks are very deep, yet the latest plasma TV series still have a slight advantage.
Viewing angle: what a clear advantage for plasma displays, more and more of a problem especially with the latest generation of LCD TVs, but ...
Do not always assume that the angle of vision is no longer an issue when comparing plasma vs LCD. The tendency - especially with the cheaper LCD TV - is the degradation of image qualityDisplay Off-Axis is accentuated with LCD than with plasma displays.
Image retention and burn-in LCD TV has a technological advantage, are not susceptible to burn-in and image retention on LCD TV - known as "ghosting", is often completely reversible.
It 'important to realize that here during burn-in plasma screens and LCD panels for ghosting is to take burn-in, but these are two completely different phenomena.
Burn-inThere is not much of a concern, as used with plasma TVs in the recent past, especially for people with normal requirements of TV operation. Similarly, the ghost of LCD TV is hard to take under normal home entertainment experience.
Viewing distance: It seems that the pixel size and shape of an LCD panel enables a fluid to a plasma of large panels for the same number of pixels.
This means that even if the viewing distancefalls within the recommended distance of about twice the width of the screen of an HDTV, if these feet less than at least nine, probably you are better off with an LCD TV.
Life time: this is a non-issue with both technologies. In reality, sets both plasma and LCD TVs are equipped with a cited half-life of 60,000 hours. Even if that only 30,000 hours, would be to use more than 14 years to 6 hours per day. And this, when the average household sizeU.S. TV replaced every 7 years!
In other words, sets both plasma and LCD TV display technologies using extremely stable and reliable. As such, life is more dependent on the quality of the manufacturer, rather than the display technology.
Answer: Plasma TVs have an advantage here, because even if the LCD technology has improved so much that this is less of a problem, but LCD has more to do to achieve the same level of the pixelsThe reaction times compared to the fluorescent screen.
Power: The advantage is LCD panels as these consume less power. Estimates show that the use of LCD panels, of which about 30% energy savings with the same screen size plasma displays.
So the choice
suffer plasma offers a larger screen for your dollar, deeper blacks, but then the LCD burn-in and - there's a market for plasma and LCD displaysmaller end of the market (less than screen size 40-inch) LCD is the only way, if you want something subtle and elegant.
It 's all a matter of knowing what are the advantages and disadvantages of each in relation to their specific needs.
