TFT (Thin-Film Transistor)

A Thin-Film Transistor (TFT) is a type of transistor used mainly in displays like TVs and smartphones. It controls tiny pixels by acting as an electronic switch, turning each pixel on or off to create images. The TFT is made of very thin layers of semiconductor material, which are placed on a glass or plastic substrate. When voltage is applied, it allows electric current to flow or stop, enabling precise control of color and brightness in each pixel. This technology produces sharp, high-quality images with vibrant colors and fast response times, making screens more clear and reliable.
