TFT refers to thin film transistor, 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. It is currently the best LCD color. One of the display devices.
The TFT-LCD liquid crystal display is a thin film transistor type liquid crystal display, also known as "true color" (TFT). TFT liquid crystal has a semiconductor switch for each pixel, and each pixel can be directly controlled by dot pulse, so each node is relatively independent and can be controlled continuously, which not only improves the response speed of the display screen, but also can be precisely controlled Display color gradation, so the color of TFT liquid crystal is more true.
TFT is a thin film transistor active matrix liquid crystal display device. TFT liquid crystal display designs a field effect switch tube on each pixel point, so that it is easy to realize the liquid crystal display device of true color and high resolution. The current TFT-type liquid crystal generally realizes more than 18bit color (218 colors), and even reaches 24bit color; SXGA (1280×1024) and even UXGA (1600×1200) have become a reality.
TFT has good brightness, high contrast, strong sense of hierarchy, and bright colors. The disadvantage is that it consumes more power and costs more. The main components of TFT-type liquid crystal displays include: fluorescent tubes, light guide plates, polarizers, filter plates, glass substrates, alignment films, liquid crystal materials, thin-mode transistors, and the like.
