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 characteristics of the TFT liquid crystal display are good brightness, high contrast, strong sense of hierarchy, and bright colors, but there are also disadvantages of relatively high power consumption and high cost. TFT LCD technology has accelerated the development of mobile color screens. Many of the new generation of color screen mobile phones support 65536 color display, and some even support 160,000 color display. At this time, TFT's high contrast and rich color advantages are very important.
The main components of the TFT-type liquid crystal display include fluorescent tubes, light guide plates, polarizing plates, filter plates, glass substrates, alignment films, liquid crystal materials, thin mode transistors, and the like.
