TFT (ThinFilmTransistor)  refers to a thin film transistor, meaning that each liquid crystal pixel is driven by a thin film transistor integrated behind a pixel, so that high-speed, high-brightness, high-contrast display screen information can be achieved. One of the best LCD color display devices at present, whose effect is close to that of a CRT monitor, is a mainstream display device on notebooks and desktops. Each pixel of the TFT is controlled by a TFT integrated on itself and is an active pixel. Therefore, not only the speed can be greatly improved, but also the contrast and brightness are greatly improved, while the resolution also reaches a very high level.
The TFT-LCD liquid crystal display is a thin film transistor type liquid crystal display, which is also referred to as "true color" (TFT). The TFT liquid crystal has a semiconductor switch for each pixel. Each pixel can be directly controlled by a point pulse, so each node is relatively independent and can be continuously controlled, which not only improves the response speed of the display screen, but also can accurately control the display screen. Display color scale, so the color of the TFT LCD is more true.
The TFT is a thin film transistor active matrix liquid crystal display device. The TFT liquid crystal display design a field effect switch tube at each pixel point, so that it is easy to realize a true color, high resolution liquid crystal display device. Today's TFT-type liquid crystals generally achieve 18-bit or more color (218 colors), or even 24 bit color; in terms of resolution, VGA (640×480), SVGA
