What is a TFT LCD Monitor? by Gostop

A TFT LCD monitor is a type of flat-panel display that works as either a computer monitor or as a television. TFT LCD is short for thin film transistor liquid crystal display. Most of the time, manufacturers shorten the term for such displays , dropping the TFT from the name. TFT simply refers to the type of LCD monitor, and TFT is easily the most popular type of LCD.

The thin film transistor in a TFT LCD monitor consists of a thin film of a semiconductor material applied over a glass substrate. Each pixel in a TFT has its own transistor along with the liquid crystal material. The liquid crystal material exhibits properties of both a liquid, because of its ability to change quickly, and a crystal, because of its ability to remain in an arranged position. The transistor applies a voltage to the pixel, determining the color and intensity of the pixel. A pixel is short for picture element, and the tiny pixels blend together to create the image on a display.

Another name for a TFT is an active-matrix LCD. Although TFT is not the only active-matrix LCD technology, it is overwhelmingly the most common type, causing some people use the two terms interchangeably. However, a TFT is only a small part of an active-matrix LCD. Active-matrix refers to the ability of a TFT LCD monitor to control individual pixels and switch them quickly.

Active-matrix LCDs differ from passive-matrix LCDs in several ways. A TFT LCD monitor has a high refresh rate, high contrast, and high response times, at least when compared to passive-matrix displays. A passive-matrix is commonly found in a calculator display or a digital wristwatch, where the display contains a limited number of segments and does not require full color. Active-matrix displays usually are high-resolution, full-color LCDs, and they include LCDs found in computer displays, cell phones, and TVs.
