What Is the TFT LCD Display?

1. What is the TFT LCD display?


The TFT LCD display refers to a thin-film transistor. Each LCD pixel is driven by a thin film transistor integrated behind the pixel so that it can display screen information at high speed, high brightness, and high contrast. It is one of the best LCD color display devices currently with a similar effect as the CRT monitor. And it is the mainstream display device now.


Each pixel of the TFT LCD display is controlled by the TFT integrated on itself, which is an active pixel. Therefore, not only the speed can be greatly improved, but the contrast and brightness are also greatly improved, and the resolution can also reach a very high level.


2. The composition of the TFT LCD display


The TFT LCD display is a thin film transistor LCD display. Each pixel is equipped with a semiconductor switch, and each pixel can be directly controlled by an electrical pulse. Therefore, each node is relatively independent and can be continuously controlled. It not only improves the response speed of the display screen, but also accurately controls the display color level. Therefore, the degree of color reduction of the TFT LCD is higher.


TFT is a thin film transistor active-matrix LCD display device. In the TFT LCD display, each pixel has a field-effect switch tube so that it is easy to realize a true-color, high-resolution LCD display device. Currently, TFT LCD generally has colors above 18bit (218 colors), and even up to 24bit colors.
