A TFT (Thin Film Transistor) is a thin film field effect transistor and is one of active matrix liquid crystal displays. It can "actively" control individual pixels on the screen, which can greatly improve the reaction time.
Generally, the reaction time of TFT is relatively fast, about 80 milliseconds, and the viewing angle is large, generally reaching about 130 degrees, mainly used in high-end products. The so-called thin film field effect transistor means that each liquid crystal pixel on the liquid crystal display is driven by a thin film transistor integrated therein.
Thereby, high-speed, high-brightness, high-contrast display screen information can be achieved. TFT is an active matrix liquid crystal display, which is driven by an "active matrix" method. The method is a transistor electrode made by thin film technology. The scanning method is used to "actively pull" to control the opening of any one display point. When the light source is irradiated, it is firstly permeable through the lower polarizing plate, and the light is transmitted by the liquid crystal molecules, and the display is achieved by shading and light transmission.
