Contrast and brightness are also greatly improved

The TFT liquid crystal screen is provided with a semiconductor switch for each pixel, and its processing process is similar to a large-scale integrated circuit. Since each pixel can be directly controlled by a point pulse, each node is relatively independent and can be continuously controlled. Such a design not only improves the response speed of the display screen, but also can precisely control the display gray scale, so TFT liquid crystals The color is more realistic.

TFT (ThinFilmTransistor) refers to a thin film transistor, meaning that each liquid crystal pixel is driven by a thin film transistor integrated behind a pixel, so that high-speed, high-brightness, high-contrast display screen information can be achieved, and it is currently the best. One of the LCD color display devices, whose effect is close to that of a CRT monitor, is now the mainstream display device for notebooks and desktops. Each pixel of the TFT is controlled by a TFT integrated on itself and is an active pixel. Therefore, not only the speed can be greatly improved, but also the contrast and brightness are greatly improved, while the resolution also reaches a very high level.

The TFT-LCD liquid crystal display is a thin film transistor type liquid crystal display, which is also referred to as "true color" (TFT). The TFT liquid crystal has a semiconductor switch for each pixel. Each pixel can be directly controlled by a point pulse. Therefore, each node is relatively independent and can be continuously controlled, which not only improves the response speed of the display screen, but also can accurately control the display screen. Display color scale, so the color of the TFT LCD is more true.
