TFT (Thin Film Transistor) LCD is a thin film transistor LCD, which is one of the active matrix type liquid crystal displays (AM-LCD).

Different from the TN technology, the TFT display adopts a "back-through" illumination method - the imaginary light source path is not from top to bottom like TN liquid crystal, but from bottom to top. This method is to set up a special light pipe on the back of the liquid crystal, and when the light source is illuminated, it is transmitted upward through the lower polarizer. Since the electrodes of the upper and lower interlayers are changed to FET electrodes and common electrodes, when the FET electrodes are turned on, the performance of the liquid crystal molecules will also change, which can achieve the purpose of display by shading and transmitting light, and the response time is greatly improved to about 80ms. Because of its higher contrast ratio and richer colors than TN-LCD, and the screen update frequency is faster, TFT is commonly known as "true color".
