What is the TFT monitor?

The

TFT monitor uses thin -layer transistor technology on the LCD display. LCD monitors, also called flat panel displays, replace old cathode tubes (CRT) on television and computer displays. Almost all LCD monitors today use TFT technology. Because each transistor is so small, there is also a small amount of charge needed to control. This allows the screen to refresh very quickly because the image is painted again or updated several times per second.

Before TFT, passive matrix LCD displays could not keep up with fast moving images. The mouse dragged over the screen, for example from point A to point B, would disappear between two points. The TFT monitor can watch the mouse, resulting in a display that can be used for video, games and all forms of multimedia.

17 -inch TFT monitor has about 1.3 million pixels and 1.3 million transistors. This leaves a significant chance for a non -functional transistor or two on the panel and "dead pixels" are not uncommon. The dead pixel is piXel, whose transistor has failed, and thus did not create any imaging image so on a solid black background, for example dead pixels protrude as small dots red, white or blue. Most manufacturers do not replace a monitor that has less than 11 dead pixels. Many have no dead pixels, even though even those who do it are not really evident if they are in a critical position on the screen.

There is only a handful of TFT factories that show panels for all monitors brands. Because there is a measure of failure - given how many transistors are in each panel - only so many displays that carry no dead pixels come out. A certain percentage has some, but not a disproportionate number and other panels are reusable. Panels that have some dead pixels are often sold to use in discount models. Consumers should therefore read online feedback from buyers to get an idea of ​​the quality of specific brands. By scanning reviews for several brands it is easy to getThe feeling that models have permanently good panels that rarely carry dead pixels.

A good TFT monitor provides sharp text, live color and improved response time for multimedia applications. People who are interested in playing games, video editing or other multimedia applications should look for a monitor with a rate of 16 ms response or less.
