How does a TFT module operate? First, TFT stands for “Thin Film Transistor,” and it describes the control elements that actively control the pixels. Because of that, you hear a lot said about active matrix TFTs. How do the images get produced? It operates on a basic principle. You have the TFT LCD display, which has many pixels, and each pixel has the ability to reveal differing colors.

TFT displays also use a backlight that comprises fluorescent tubes to light a single pixel. When a small shutter gets opened, the light passes through. Of course, this technology is more detailed than what can fit in this article, but a simple explanation can give you an idea of how it works.
