What is TFT LCD Screen

The main structures of TFT LCD screens include fluorescent tubes, light guide plates, polarizing plates, filters, glass substrates, alignment films, liquid crystal materials, transistors, etc.

TFT is a thin film field effect transistor, which is a type of active matrix liquid crystal display. It "actively" controls every pixel on the screen, which can greatly improve response times.

Generally, the response time of TFT is relatively fast, about 80 milliseconds, and the visual amplitude increases, generally close to 130 degrees. It is mainly used in high-end products. The so-called transistor transistor means that each liquid crystal pixel on the liquid crystal display is driven by the integrated transistor behind it.

Therefore, high-speed, high-brightness, and high-power consumption display screen information can be achieved. The TFT screen is an active matrix liquid crystal display and is technically driven by the "active matrix" method. The method is to use thin film technology to make transistor electrodes, and when the scanning method is used to "actively" switch, the light source is first upwardly exposed to the lower polarizer when irradiated, and the light is transmitted through the liquid crystal molecules, and the purpose of display is achieved through light shielding and light transmission.
