What is the difference between TFT Monitor and LCD Moniter? Which is the best? and Why?

Question

There are many different types of Moniters in the market-CRT, TFT, LCD etc. I would like to know is there any difference in display,? Which is the best for the eye to view without much strain ?

Answer 1

A TFT monitor uses thin-film transistor technology for the ultimate LCD or liquid crystal display. LCD monitors, also called flat panel displays, are replacing the old style cathode ray tubes (CRTs) as the display of choice. Nearly all LCD monitors today use TFT technology.

The benefit of a 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 TFT, passive matrix LCD displays could not keep up with fast moving images. A 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.

A typical 17-inch TFT monitor has about 1.3 million pixels and 1.3 million transistors. That leaves a 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 a 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.

A 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. The DVI (digital visual/video interface) is also a good feature to get, as it will make the monitor more future-proof.

It is pretty easy Guru, A liquid crystal display (commonly abbreviated LCD) is a thin, flat display device made up of any number of color or monochrome pixels arrayed in front of a light source or reflector. It is prized by engineers because it uses very small amounts of electric power, and is therefore suitable for use in battery-powered electronic devices. TFT-LCD (Thin Film Transistor-Liquid Crystal Display) is a variant of Liquid Crystal Display (LCD) which uses Thin-Film Transistor (TFT) technology to improve image quality. TFT LCD is one type of active matrix LCD, though it is usually synonymous with LCD. It is used in both flat panel displays and projectors. In computing, TFT monitors are rapidly displacing competing CRT technology, and are commonly available in sizes from 12 to 30 inches. As of 2006, they have also made inroads on the television market. This is only my personal view, and for more information you can visit the above links..and i think this answer was elaborate and hoping this would help you better. WAS THIS INFORMATION HELPFUL?

The CRT is the original type of display used with computers, they started out in Black and White, Green on Black, Amber on Black, etc. Now a days, they are color, your pricing on them starts out very inexpensive and can be quite expensive depending features, size, manufacturer's name reputation, etc. Most of the time when you deal with CRTs, you pick your size, select a brand name you like, and then look at the Dot Pitch, usually trying to get the lowest number you can. Dot Pitch is the spacing between the pixels of the screen, so in this case, a CRT monitor rated at .24 is going to give you a nicer picture than a CRT at .27. Another example of a CRT would be your typical Television before LCD or Plasma. CRT monitors are the bulkiest in design.

TFT is a variation of LCD. TFT-LCD (Thin Film Transistor-Liquid Crystal Display) is a variant of Liquid Crystal Display (LCD) which uses Thin-Film Transistor (TFT) technology to improve image quality. TFT LCD is one type of active matrix LCD, though it is usually synonymous with LCD. It is used in televisions, flat panel displays and projectors. Just like CRTs, LCDs come from many manufacturers, though they have not been on the market any where as long as the CRT. Older LCDs had a shorter lifespan versus a CRT, but most LCDs produced today can last as long as a color CRT with proper care. All laptop computers are equipped with an LCD display. Desktop LCDs generally start around 14inch and can go all the way up to 60+ inches diagonally measured. When choosing an LCD display, pick your size, normal or wide screen format, find a brand you like in your price range, then look at the response time. Just like the CRT Dot Pitch, you really want the smallest number in milliseconds you can get. Fluid motion picture replays of movies and video streaming will look most life like on an LCD with a 2ms response time. I generally use Samsung or Viewsonic for big name brands, but I have also used smaller brand names depending on my clients needs and price range.

LCDs are today's technology, CRTs while still a strong seller, are yesterdays technology. Either can be the best depending on whether you sit at an appropriate distance from the screen, though I believe LCDs will cause less overall strain because of their new technology.

Answer 4

tft is lcd. lcd's are called tft lcds. tfts are not there own type of display.
