A Thin Film Transistor (TFT) is a specialized type of field-effect transistor fabricated by depositing thin layers of semiconductor, dielectric, and conductive materials onto a substrate such as glass or flexible plastic. TFTs serve as individual switches for each pixel in a display, making them a fundamental component in modern flat-panel technologies. Their ability to provide precise control over pixel brightness and color has made them indispensable in consumer electronics, industrial equipment, automotive displays, and medical imaging systems.
