Thin-film transistors (TFTs)

Thin-film transistors (TFTs) are a type of electronic switch used primarily in displays like LCD screens. They consist of a very thin layer of semiconductor material, such as amorphous silicon or organic compounds, placed on a flat surface. When an electric voltage is applied, the TFT controls the flow of electrical current to individual pixels, enabling precise control over brightness and color. This technology allows for high-resolution, flat-panel displays used in TVs, smartphones, and monitors. TFTs are valued for their speed, stability, and ability to produce sharp, clear images.
