What is the difference between TFT and LCD screens?
TFT stands for thin-film transistor. These transistors are used in high-quality liquid-crystal displays (LCDs) for flat panel screens. A TFT screen is a kind of LCD screen, as opposed to a different type of screen.Pixels and TransistorsEach pixel of a TFT screen has its own transistor, which allows the electrical current that illuminates the screen to be turned on and off faster than in other types of LCD screens. Essentially, each pixel has its own on-off switch.EffectsTurning the electrical current on and off more quickly creates a brighter display and shows motion more smoothly, both important features in televisions and computer monitors.Active vs. Passive MatrixA TFT display is an active-matrix LCD screen. It is a higher quality screen than a passive-matrix LCD screen.MaterialsThe film in a TFT screen is usually made of silicon.
