TFT screen is currently the most commonly used and most common material on mobile phone screens. TFT full-process TFT–ThinFilmTransistor thin film transistor is one of the active matrix type liquid crystal displays AM-LCD. phone display TFT is equipped with a special light tube on the back of the LCD. , Can actively control each independent pixel on the screen, which can greatly improve the response time.
Since the TFT is an active matrix LCD, the arrangement of the liquid crystal can be memorized and will not return to the original state immediately after the current disappears. TFT also improves the STN flicker (water ripple)-blur phenomenon, effectively improving the ability to play dynamic pictures.
TFT liquid crystal has 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 can be accurately controlled Display color gradation, so the color of TFT liquid crystal is more real. The TFT liquid crystal display is characterized by good brightness, strong layering, and bright colors, but it also has the disadvantage of relatively power consumption.
