    Bonjour

    TFT stands for "thin-film transistor" and it is a type of technology used by LCD (liquid crystal display) screens. Older LCD screens used a type of display called "passive" and they were plagued with ghosting and slow refresh rates. "Active" technology using thin-film transistors makes for brighter and faster screens, so all current color LCD displays use TFT technology.

    Plasma is another display technology that competes with LCD. Plasma technology works by exciting pixels with a plasma discharge between two glass plates. It is fairly exotic technology and it can produce exceptionally pleasing pictures. That's why plasma screens are generally more expensive than LCD.

    Its quiet confusing as well, at first, but really simple if you look into it, i found it teh same.

    good luck my friend

    TFT monitor uses thin-film transistor technology for the ultimate LCD display. LCD monitors, also called flat panel displays, are replacing the old style cathode ray tubes (CRTs) as the displays of choice. Nearly all LCD monitors today use TFTTFTTFT technology. The benefit of aaa TFT monitor is a separate, tiny transistor for each pixel on the display. Because each transistor is so small, the amount of charge needed to control it is also small. This allows for very fast re-drawing of the display, as the image is re-painted or refreshed several times per second. Prior to TFTTFTTFT, passive matrix LCD displays could not keep up with fast moving images. AAA mouse dragged across the screen, for example, from point A to point B, would disappear between the two points. A TFT monitor can track the mouse, resulting in a display that can be used for video, gaming and all forms of multimedia. AAA typical 17-inch TFT monitor has about 1.3 million pixels and 1.3 million transistors. That leaves aaa significant chance for a malfunctioning transistor or two on the panel. Upon delivery, a TFT monitor can have "dead pixels" for this reason. A dead pixel is a pixel whose transistor has failed, thereby creating no display image. On a solid black background, dead pixels will stand out as tiny dots of red, white or blue. Most manufacturers will not replace a TFT monitor that has less than 11 dead pixels. Often, a TFT monitor won't have any dead pixels —- always the hope for any buyer, though dead pixels are not noticeable unless located in a critical position on the screen. There are only aaa handful of TFT factories that turn out panels for all brands of TFT monitors. Since there is a given failure rate -- considering how many transistors are on each panel -- only so many of the displays come out bearing no dead pixels, while a certain percentage bear an acceptable number of dead pixels and other panels are unusable. The panels that bear some dead pixels are often sold to be used in discount models. If looking for a TFT monitor, it is a good idea to read feedback provided by buyers at popular online retail sites. By scanning the reviews for several brands, it is easy to get a feel for which models have consistently good panels that rarely bear dead pixels. AAA TFT monitor delivers crisp text, vibrant color and an improved response time for multimedia applications. If interested in gaming, video editing or other multimedia applications, look for a TFT monitor with a response rate of 16ms or less. .

    LCD TVs are the most common, and have good quality. TFT is a type of LCD screen.

    Plasma TVs are more expensive, but can provide higher quality and better colours.

    When purchasing a screen over 50", it is preferrable to use Plasma. Anything less and you go for LCD.

    I know that a plasma is different from the rest because it uses water(plasma) to make an image and I thing the others are just different quality of TV with no water in the.the plasma is so much nice and bigger and has hd(high definition) so really the best TV is plasma and if you want to put it in you bedroom then your should look up ways to put it on your wall with no stand =^0

    All of this HDTV stuff can be confusing. Plasma produces the best color rendition. LCD would be your next choice. TFT would be last choice. You can find out about all these different types and all the options for HDTV in a guide called HDTV Simplified. You can get it at http://www.HDTV-Simplified.com . This $7 guide can acutally save you hundreds of dollars on your next HDTV purchase. It shows you have to get the best HDTV for you personal style.

    Merry Christmas

    Plasma - gas under pressure inside glass structure which emits light and generates the colored pixels making up the TV picture

    LCD - liquid or moving crystaline structure which determines how white light passes through it and hence colors its pixels in accordance with the TV picture

    plasma screen is made of gas

    lcd speaks for itself and is loads of little dots

    and tft is similar to lcd

    Plasma is gas in tubes that are excited by tiny current.

    LCD is crystals that are excited by tiny current and they turn depending on amount of current.

    TFT .... i dk.

    Go to http://www.tigerdirect.ca and look at the simple explanation they have on their website about all these technologies.

    It gets larger and larger. From a 1 ruler size in square to a very large TV now.
