Though both LCD and plasma are available in the form of thin flat panel displays, but from a technological point of view, these two flat panel displays process the image differently.
Plasma uses a matrix of small gas plasma cells charged by precise electrical voltages to emit light and create the image by image. Liquid Crystal Display (LCD) - work by trapping a liquid crystal solution between two sheets of polarized glass. When an electricalCurrent is passed 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 is not the scope of this article for details about the issue in terms of how these different display technologies vision - after all, what really counts is not what happens behind the screen, but Rather how thesedifferent display technologies work as a TV screen. At the same time, it is worth noting that it is these differences that each technology will give this, their strengths and weaknesses, and therefore makes a better choice than others under certain circumstances.
The following list shows the main differences between these two flat-screen technologies:
Format: For the momentConflict between plasma and LCD-TV area occur in 40-50 inches. In fact, most LCD TVs up to 50 inches, larger screen sizes are also available, although the selection is still very limited. This means that anything larger than 50 inches, a plasma display is your only real option if what you are after is a system-view satellite television. On the other hand, the smaller end of the spectrum, namely 15 "to 36" TV, LCD is the way to go if what you wantis something elegant and thin (less than 4 cm deep).
Value: This field is leveling at a fast rate. Until very recently, plasma is the obvious choice for all screen sizes where collision between these two technologies occurs, that is no longer the case. In general, plasma still leads by a good margin only in larger screen sizes - 50 inches and up. To small (up to 44-inches), the price advantage when it comes to plasma vsLCD TV, LCD TV shift begins more.
Total Video Performance: Both the latest plasma and LCD flat panel TFT display capable of excellent image quality - with bright and crisp. However, plasma flat panel monitors are more suitable to use basic home theater screen. The cell structure of gas inside a plasma display is such that the light is not lost between adjacent cells (or pixels). This plasma display makes it suitableDisplay deeper blacks - and therefore more suitable for television and film scenes in which dark and light content is shown more than once.
In comparison, the nature of LCD technology - where a backlight passes through the layer of liquid crystal - which is hard for him to reach the "real" blacks (ie true absence of light), because more light loss adjacent pixels.
This does not mean that LCD panel s are not suitable for use as TV screens, LCD TV todayextremely high contrast panels able to display very deep blacks, but the latest plasma TV still have a slight advantage.
Viewing angle: what was a clear advantage for plasma displays is more and more of a non-issue especially with the latest generation of LCD televisions, but ...
Do not always assume that viewing angle is no longer an issue when comparing plasma vs. LCD TV. The tendency - especially with the cheaper LCD TVs - isthat the deterioration of image quality with off-axis viewing more than with LCD plasma, with emphasis.
persistence and burn-in LCD TVs has a technological advantage, they are not susceptible to burn-in and image in the LCD - retention named as "stick image" is often completely reversible.
It 'important to recognize here that during the burn-in stick in plasma displays and LCD panels is in bringing an image to burn, but thesetwo completely different phenomena.
Burn-in is not so important, as it uses a plasma TV in the recent past, particularly for people with normal television standards. Similarly, attack with LCD TV image can not intervene in the normal home entertainment experience.
Viewing distance: It seems that the pixel size and shape of an LCD panel enables a softer image quality as equivalent to a large plasma panel for the same pixelcount.
This means that even if your viewing distance falls within the recommended distance of about twice the width of the screen of an HDTV, if lower than at least nine feet, you'll probably be better with an LCD TV.
Lifespan: this is not a problem with both technologies. In fact requires both plasma and LCD TVs have a cited half-life of 60,000 hours. Although only 30,000 hours, which would mean that more than 14 years when used6 hours per day. So, if the average size of households in the U.S. TV replaced every seven years!
In other words, use both plasma and LCD extremely stable and reliable display technologies. As such, duration more dependent on quality rather than the manufacturer's display technology.
Answer: Plasma TVs take an advantage here, because even though LCD technology has improved in some extent this is becoming less and less, yet LCDstill a long way to go to reach the same level of pixel response time, such as listings of phosphorous.
Power: The advantage here goes to power as LCD panels consume them less. Estimates indicate that the use of LCD panels can result in% energy savings, around 30 for the same screen size plasma.
For Decision
Is there a market for plasma and LCD - Plasma provides a larger screen for yourDollar, deeper blacks, but the LCD does not suffer burn-in and the bottom end of the market (less than 40 inches diagonal), LCD is your only way forward if you want something slim and elegant.
It's all a matter of knowing what are the advantages and disadvantages of each in relation to your specific needs.
