What is the internal structure of a TFT LCD display? part one

TFT-LCD liquid crystal display is a thin film transistor type liquid crystal display, also known as "true color" (TFT). TFT liquid crystal is equipped with a semiconductor switch for each pixel. Each pixel can be directly controlled through point pulses. Therefore, each node is relatively independent and can be controlled continuously. This not only improves the response speed of the display screen, but also allows precise control. Display color gradation, so the colors of TFT LCD are more realistic.

In the fierce competition among many flat-panel displays, why TFT-LCD can stand out and become a new generation of mainstream displays is by no means accidental. It is an inevitable result of the development of human science and technology and thinking patterns. Liquid crystals have successively avoided the difficult problem of luminescence, and used the excellent characteristics of liquid crystals as light valves to decompose the luminescent display device into two parts, namely the light source and the control of the light source. As a light source, brilliant results have been achieved in terms of luminous efficiency, full color, and lifespan, and they are still being deepened.
