TFT (ThinFilmTransistor) refers to thin film transistors, which means that each liquid crystal pixel is driven by a thin film transistor integrated behind the pixel, so that it can display screen information at high speed, high brightness, and high contrast, which is currently the best One of the LCD color display devices, its effect is close to CRT monitors, and it is now the mainstream display device on notebook computers and desktop computers. Each pixel of the TFT is controlled by the TFT integrated on itself, which is an active pixel. Therefore, not only the speed can be greatly improved, but the contrast and brightness are also greatly improved, and the resolution has also reached a very high level.
The TFT-LCD liquid crystal display is a thin film transistor type liquid crystal display, also known as "true color" (TFT). TFT liquid crystal is equipped with a semiconductor switch for each pixel, and each pixel can be directly controlled by dot pulses, so each node is relatively independent and can be continuously controlled, which not only improves the response speed of the display screen, but also allows precise control Display color gradation, so the color of TFT liquid crystal is more real.
TFT is a thin film transistor active matrix liquid crystal display device. The TFT liquid crystal display designs a field effect switch tube on each pixel, so that it is easy to realize a true-color, high-resolution liquid crystal display device. The current TFT-type liquid crystals generally achieve 18-bit or more color (218 colors), even up to 24bit color; in terms of resolution, it achieves VGA (640480), SVGA (800600), XGA (1024768), SXGA (12801024) and even UXGA (16001200) have become a reality.
