TFT is the abbreviation of thin film transistor, which means that each liquid crystal pixel on the liquid crystal display is driven by a thin film transistor integrated behind it, so that screen information can be displayed at high speed, high brightness and high contrast. , TFT-LCD is a type of most liquid crystal displays.

#TFT is the abbreviation of thin film transistor.

TFT means that each liquid crystal pixel on the liquid crystal display is driven by a thin film transistor integrated behind it. This allows high-speed, high-brightness, and high-contrast display of screen information. TFT-LCD (Thin Film Transistor Liquid Crystal Display) is a type of most liquid crystal displays.

TFT display is a mainstream display device on various laptops and desktops. Each liquid crystal pixel on this type of display is driven by a thin film transistor integrated behind the pixel, so TFT The LCD display is also a type of active matrix liquid crystal display device. Is one of the best LCD color monitors.

TFT display has the advantages of high responsiveness, high brightness, high contrast, etc., and its display effect is close to that of CRT display.

Extended information

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

Different from TN technology, TFT display uses a "back-transmission" 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 shines upward through the lower polarizing plate.

Since the upper and lower interlayer electrodes 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. The purpose of display can be achieved by shading and transmitting light, and the response time will be greatly improved. Increase to about 80ms. Because it has higher contrast and richer colors than TN-LCD, and the screen update frequency is faster, TFT is commonly known as "true color".
