الإثنان يدلان على مفهوم واحد وهي الشاشة ال LCD
LCD= Liquid Crystal Display
أي شاشة عرض تعمل بالكريستال السائل
أما TFT فهو :
TFT - Thin film transistor
A type of LCD that is sometimes called an active matrix. TFT is actually a component of a an LCD to improve the quality and control of the LCD display. It is basically a tiny transistor linked to each individual pixel on the screen.
These transistors are used in high-quality flat panel liquid-crystal displays (LCDs). TFT-based displays have a transistor for each pixel on the screen. This allows the electrical current that illuminates the display to be turned on and off at a faster rate, which makes the display brighter and shows motion smoother. LCDs that use TFT technology are called "active-matrix" displays, which are higher-quality than older "passive-matrix" displays. So if you ever see a TFTAMLCD monitor at your local computer store, it is a "thin-film transistor active-matrix liquid crystal display." Basically, it is a high-quality flat screen monitor.
