What is an active-matrix liquid crystal display? Also known as TFT Display, or Thin Film Transistor Display. An active matrix liquid crystal display is the display industry’s term for the type of flat panel display that is currently the overwhelming choice of notebook computer manufacturers, due to light weight, very good image quality, wide color gamut, and response time. With active matrix displays, each pixel is controlled by a switch-device which actively maintains the pixel state while other pixels are being addressed. This generally makes the screens faster, brighter, and more colorful then passive matrix control of each pixel, while preventing crosstalk from inadvertently changing the state of an unaddressed pixel.
