TFT LCD

1. What is TFT meaning?   What role does TFT play in the LCD screen?

TFT (Thin Film Transistor) is the abbreviation of Thin Film Transistor. Thin-film transistors, also known as TFT components, or TFT switching tubes, are based on the principle of field-effect tubes, that is, TFT components are tubes that use electric field effects to control current. In actual use, TFT, as a switching device, only plays an on or off role in determining whether the liquid crystal is charged or not. When the thin film transistor is on, the voltage output from its source electrode is used to charge the liquid crystal and memory capacitor. The charging voltage is determined by the driving circuit of the liquid crystal screen. TFT can be used with LCD to better control its rendering image and color to improve image quality and display more realistic.

2. What is  TFT-LCD?

Thin film transistor liquid crystal display (often referred to as TFT-LCD) is one of the most liquid crystal displays,  Each liquid crystal pixel on this type of display is driven by a thin film transistor integrated behind the pixel, each pixel has four (one black, three RGB colors) independent thin-film transistors to switch four transistors according to the color signal sent by the driver IC. It is precisely because each pixel can be precisely controlled, so TFT-LCD display is more realistic. The 8bit TFT panel is equivalent to having 2 to the power of 24(8*3) 16.7m colors, that is, 24-bit true color.
